All of these are all-in-one — battery, case and antenna included, nothing to solder. All are nRF52840, which is what lets a dead radio be rescued in the desert with no internet.
Prime is effectively required
Free shipping runs about five days, so an order placed Wednesday without Prime lands around Monday 24 August — too late. With Prime, order by Wednesday 19 August. Without it, order today or tomorrow, or have Blake handle it.
The safest all-rounder, and on Burning Mesh's own recommended list. Ships ready to use. Its OLED washes out in direct sun, which is the one thing the e-ink units do better.
View on Amazon →E-ink and GPS in a finished package, no assembly questions. Smallest battery of the units with a screen, which tells over nine days.
View on Amazon →Cheapest on the page and the best dust sealing of anything here. No screen, so it only works with your phone in hand.
Read this first. The M3 ships in two radio versions and they are not interchangeable. Buy this exact listing. A cheaper 'LR1110' M3 listing exists with the same product name and may not work on the mesh at all.
View on Amazon →Credit-card sized, dust-sealed, and the fastest to arrive. But no screen, and upstream puts its playa battery life at 'right over a day'. Good second node, poor only node.
Read this first. This is the one model reported to have actually failed on playa in 2025. As a second radio that is fine. As your only radio you have no fallback when it goes.
View on Amazon →Also a Qi2 power bank, so it charges your phone too. No GPS — you can message camp but they can't see where you are.
View on Amazon →The big power bank version. Still no GPS. Tightest delivery date on the page, so order it early or not at all.
View on Amazon →Sips power when idle - the best standby draw here. Small battery though. Not related to the Heltec dev boards on the avoid list.
Read this first. The listing markets this for a different mesh network, so we could not confirm this exact unit works on the 2026 mesh. Bench-test it before you rely on it.
View on Amazon →Buying it yourself? Tell Blake anyway. He flashes and configures radios at camp, and the headcount is how he plans for it — being counted takes a few seconds and doesn't commit you to anything. Count me in.
Camp already has a solar node. A repeater mounted high on the shade structure extends range for everyone — Blake is running one from gear the camp already owns, so nobody needs to buy one.
Being in the flasher's device list is not an endorsement. Every radio below has a working 2026 build — the flasher only answers whether the firmware compiles, not whether the thing survives a week in the dust.
Burning Mesh: everyone who brought one to their meetup needed reflashing after dust and heat corrupted the firmware. General reviews rank it highly — playa experience wins.
ESP32, so recovery in the field needs a laptop rather than dragging a file onto a drive. Burning Mesh: eats battery, gets hot, and some versions corrupt their own firmware when the battery runs low.
Burning Mesh: old hardware, awkward to carry, eats battery.
ESP32 dev boards in a bundle. Avoid-list hardware wearing an all-in-one costume.
Never switch a radio on without its antenna attached. It can permanently damage the transmitter. And buy the 915 MHz US version — an 868 MHz European unit won't talk to anything on the playa.
