The disaster.radio hardware is as open-as-possible. Currently, we have the schematic, BOM, and circuit board design for a development board that you can, theoretically, print yourself or order from a circuit board manufacturer of your choice.

Features

ESP32-WROOM integrated WiFi + BLE microcontroller
Dual LoRa modules
Micro-SD card slot
Micro-USB port for serial debugging
Battery connection
Battery charging module (currently using TPS6216)

Developement

Our hardware was designed in KiCad, if you would like to edit the board deisgn or take a closer look at the schematics you can download and install KiCad for your system.

After installing, open KiCad, choose File > Open Project..., navigate to where you cloned this repo, and select the file hardware/board_esp32_v2/board_esp32_v2.pro. You can now open and view the schematic and pcb design.
