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.
- 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)
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.
