Your network · what to buy

The devices

Before you tap any button: in the United States the only legal band is 915 MHz, and the frequency is BOUGHT, not configured. Why, and what happens if you get it wrong

As an Amazon Associate I earn from qualifying purchases. Put plainly: if you buy, I earn a commission and it costs you nothing extra. How it works

Build yours

One question, and it changes how many devices you need. Answer nothing and you still see everything.

Who are you going to talk to?

One by one

Filter by what matters to you

Assembled: out of the box and done 7

They arrive with their case and their battery already in, both stated by the maker or by the listing. Charge them, open the app, and they work. The only thing separating them here is whether you can type without pulling out your phone.

No keyboard: the phone types for you 3

Just as ready to use, but writing needs the phone over Bluetooth. In exchange they are smaller, cheaper and last longer.

SenseCAP T1000-E

SenseCAP T1000-E

nRF52840

On its battery: days, depending on how often it reports

The easiest of the lot, and the only one you cannot get the band wrong on.

The size of a credit card and sealed shut: nothing to solder, no case to buy, no cell to source. Charge it, open the Meshtastic app and it is talking. If this is your first node, or a present for someone who does not want to learn any of this, it is this one.

This is the only one on the list you do not have to get the frequency right on: it is a single part covering 863 to 928 MHz and the region is chosen in the app, not at checkout. Seeed's own wiki says so and its bullet points repeat it in all three stores. Its listing states no band, and here that is not a gap: there is no fixed band to state.

Built-in antenna: it comes fitted and cannot be swapped.

Comes with its battery: it turns on the moment you open the box.

LILYGO T-Echo

LILYGO T-Echo

nRF52840

On its battery: days to more than a week

The pocket one, with an e-paper screen.

It draws the least power of all of them. E-paper only spends when it changes, so you can leave it on in your bag all weekend without thinking about the battery. It has GPS.

Its listing does not say whether an antenna is included. That is not a no: it simply does not say, and we do not make it up.

ThinkNode M5

ThinkNode M5

ESP32-S3

On its battery: over 48 hours, per its own listing

The one that arrives assembled, with a case, an e-paper screen and a battery in it.

It is the opposite of a bare board: it comes closed, with its 1200 mAh battery and an e-paper screen that reads in sunlight and spends nothing when it does not change. Of the ones you can use the day they arrive, this is the most complete.

It comes with an antenna. You can swap it: its connector is RP-SMA.

With a keyboard: you type without the phone 4

They bring their own keyboard and screen. They are the only ones you can send a message from with your phone switched off, or left at home.

M5Stack Cardputer Adv

M5Stack Cardputer Adv

ESP32-S3

On its battery: a few hours

The pocket one with a keyboard, for people who already know their way around.

It is the only one with a keyboard that still fits in a pocket, and it arrives built, with its case and its battery. But it is NOT the device to start on, and that has to be said before anyone orders it: its radio is sold separately — without it this is a little computer, not a node — it gives no coverage to the neighbourhood, which is what a fixed node with an outdoor antenna does, and apps for the old Cardputer do not run on the Adv, which reads its keyboard a different way.

The antenna comes with its radio, sold separately: an RP-SMA 3 dBi, per the cap's listing.

And if you bought the Cardputer, it is missing the radio

And if you bought the Cardputer, it is missing the radio

M5Stack's official LoRa 1262 cap gives it the SX1262 — the same radio the other boards carry — and GPS. Without it the Cardputer is a little computer with a keyboard, not a node: it powers on, looks perfect, and finds nobody.

It is sold separately and comes in no Cardputer box. Check before you order: this is the mistake that leaves the device pretty and mute.

LILYGO T-Deck Plus

LILYGO T-Deck Plus

ESP32-S3

On its battery: tens of hours

The one that needs no phone: it brings its own keyboard and screen.

Every other one is driven from your phone over Bluetooth. Not this one: you type on it directly, so it works when the phone is out of battery or when you want a device that depends on nothing else.

Built-in antenna: it comes fitted and cannot be swapped.

T-Lora Pager

T-Lora Pager

ESP32-S3

On its battery: depends on the cell you fit

The one that looks like a pager: colour screen, keyboard and NFC.

LilyGO's newest, and the closest thing here to a finished pocket device, with a 2.3-inch colour screen. It sits down here rather than up top because it needs a cell bought separately, and the 18650 is exactly what this guide cannot sell you.

It comes with an antenna. And it cannot be swapped: it is soldered on.

T-Deck Pro

T-Deck Pro

ESP32-S3

On its battery: on mains or on a LiPo

The keyboard one with an e-paper screen, for writing properly.

It is the T-Deck Plus's sibling with e-paper instead of LCD: readable in sunlight, far lower power draw, antenna built in. If what you want is to write long messages without pulling out your phone, this and the Plus are the only two on the list with a keyboard.

Boards: something is missing before it works 2

They fit in a backpack too, but you have to add something first — a cell, a case, or a check on which firmware they shipped with. Not worse: another purchase, with one more step.

No keyboard: the phone types for you 2

Just as ready to use, but writing needs the phone over Bluetooth. In exchange they are smaller, cheaper and last longer.

RAK WisBlock Starter Kit

RAK WisBlock Starter Kit

nRF52840

On its battery: days to over a week

The one that arrives assembled, with the software already on it.

It is the only one you do not have to set up: it ships with the Meshtastic firmware already installed, so you power it on, pair your phone and it is talking. It carries the same low-power chip as the T-Echo — days to over a week on one charge — and costs a little over half as much. It is also the maker Meshtastic lists first in its supported-hardware documentation.

It comes with an antenna. You can swap it: its connector is IPEX.

The battery is NOT included. You add: A LiPo battery with a JST connector.

LILYGO T-Beam

LILYGO T-Beam

ESP32-S3

On its battery: tens of hours

The one with GPS and a swappable 18650 cell, to carry and to leave running.

It is the cheapest with GPS and a replaceable battery: when it runs out you swap the cell up a mountain instead of hunting for a socket. In exchange, the ESP32 chip draws about ten times what the T-Echo does.

It comes with an antenna. You can swap it: its connector is IPEX.

The battery is NOT included. You add: A FLAT-TOP, UNPROTECTED 18650 cell. Button-top and protected ones run close to 70 mm and will not fit the holder.

The repeater: mount it once, it reaches for everyone 2

A rooftop, a pole, a hill: you mount it once and forget it. What decides here is power and a weatherproof case, not the screen. Mind the word: «repeater» is what it DOES, not the setting you tap — that one is CLIENT_BASE, and the guide says why.

Heltec LoRa 32 V3

Heltec LoRa 32 V3

ESP32-S3

On its battery: runs on mains

The cheap one that stays plugged into the wall.

It is the most common device on the whole network and the cheapest of all. With the ESP32 chip the battery lasts little, which is why this is the one that stays plugged in: there the power draw stops mattering and price takes over.

Same as the T114: Heltec's listing does not state the band, and the one that works here is this store's. Check it on the board before powering it on. This is the cheapest of the list, which is exactly why the warning matters more here than anywhere.

It comes with an antenna. You can swap it: its connector is IPEX.

The battery is NOT included. You add: A LiPo battery with a JST connector. The board carries the charging circuit, not the cell.

Heltec Mesh Node T114

Heltec Mesh Node T114

nRF52840

On its battery: days to more than a week

The one you leave on a rooftop and forget about.

Same low-power chip as the T-Echo but built to stay outside, and it is the one people set up as a repeater. It is also the model that carries half the world's mesh.

Its listing does NOT state the band — none of Heltec's eight listings do — and the one that works here is this store's. The band is printed on the board: check it BEFORE powering it on, which is step 2 of this guide, and if the 868 one arrived, send it back. The listings that do write «915 MHz» in the title are resellers, not the maker.

It comes with an antenna. You can swap it: its connector is IPEX.

The battery is NOT included. You add: A LiPo battery with a JST connector, or just run it off USB-C.

These also hold up left in place, but their card lives above: that is where you buy them and where what they are missing is explained.

Remember it takes two. They can be two of the same or one of each kind: the one that stays plugged in can be the cheap one, the one you carry cannot.

What you add afterwards

Two different things, and they are worth not confusing. Solar kits DO extend the network — not because of their antenna, but because they are another node, and one more node is more coverage. Antennas do NOT take you further — height does that, it is free, and it is explained above: what they give you is margin, so the link survives the trees, the walls and the rain in the way.

La pila que les falta

La pila que les falta

Litio-polímero de 3,7 V con conector JST PHR-2 de 2 mm, que es el del RAK: trae el circuito de carga y no la celda. Es la única marca que aparece en las tres tiendas con su nombre y publica lo que una falsificación nunca publica — capacidad TÍPICA y MÍNIMA (2000 y 1900 mAh), peso, medidas al milímetro y certificación con número de archivo: UL MH20555, buscable en el directorio de UL, más IEC62133-2 y UN 38.3. Lleva protección PCM contra sobrecarga, sobredescarga, sobrecorriente y cortocircuito.

ES PARA EL RAK, Y NO PARA LAS HELTEC. Las placas Heltec —la V3 y la T114 de 868— llevan un conector SH1.25 de 1,25 mm y éste es de 2 mm: no entra, y forzarlo no es una opción. Además no cabría: la caja de las Heltec admite pilas de hasta 42 mm de largo y ésta mide 56. Para esas dos, la pila viene con la placa o se compra su celda aparte. · Y MIRA LA POLARIDAD ANTES DE ENCHUFARLA: el conector JST no tiene polaridad estandarizada y el propio anuncio lo avisa en su primera viñeta —«¡Polaridad del conector — esto no es universal!»—. Al revés hace cortocircuito, y es la única pieza de esta guía que mal puesta puede quemar el aparato. Mide 34,5 × 56 × 10,6 mm.

Cámbiale el látigo, sin adaptadores

Látigo de goma de 2,5 dBi con SMA MACHO, que es el que entra: la placa lleva la hembra. Su anuncio nombra el T-Beam y el T-Echo, y sirve en las de RAK, LilyGO, Heltec y Seeed con conector SMA.

Es de 915 MHz, la banda de esta tienda. Cuidado al comparar: las hay vendidas en «SMA hembra», que no enroscan en nada.

La de exterior, para el que se queda fijo

Omnidireccional de 6,5 dBi en kit, con un metro de cable SMA, soporte de mástil e IP66. Es la única antena de esta guía que vale en las tres tiendas: cubre de 824 a 960 MHz, o sea 868 y 915 con la misma pieza.

Pesa, va en un mástil y hay que subirla. Y su ganancia cuenta dentro del límite legal de potencia de esta tienda: puede tocar bajarle al aparato.

La caja solar sola, si ya tienes la placa

La caja solar sola, si ya tienes la placa

Panel de 5 W, carcasa IP67 con cara de vidrio templado y antena de 915 MHz. NO trae la placa: es para meterle una Heltec V3, V4 o T114.

Su título dice «only case» al final y en inglés, donde nadie lee: como repetidor completo es una trampa cara. Y le faltan las cuatro celdas 18650, que aquí no se venden.

El solar que llega listo y con pilas

El solar que llega listo y con pilas

Trae la placa, no es sólo la caja: su anuncio lo dice —«construido alrededor del Nordic nRF52840», con panel solar y batería recargable— y Meshtastic lo remata, «Pre-flashed with Meshtastic firmware», que a una caja vacía no se le instala. Y tres cosas más, de la documentación de Meshtastic y no del vendedor: cubre 862 a 930 MHz en UNA pieza, así que la banda no se puede equivocar; llega con el programa puesto; y la versión Pro viene con cuatro celdas 18650 de 3350 mAh.

Es el que recomiendo para dejar puesto: a una azotea se sube UNA vez, y ahí lo barato se paga en viajes. Para cambiarle la pila, su anuncio exige 18650 de BOTÓN — al revés que el T-Beam, que las pide planas.
