The RAK WisBlock is a low power modular hardware system that can be used to build Meshtastic devices. Soldering is only required for the optional OLED screen.
You will need a base board, a core 4631 LPWAN module, and optionally a GPS Sensor to build a Meshtastic device.
Both available base boards (5005 & 19003) have a reset button, support an OLED screen, and have built in connectors for a 3.7V LIPO battery (max 4.3V) and 5V Solar panel (max 5.5V)
A user button is not possible with the 19003 base board. It may be possible to add a user button to the 5005 base board using the 13002 IO module.
To add a GPS to the 5005 base board, you need the 1910 GPS sensor. It is supported on slot A of the 5005 board via UART.
To add a GPS to the 19003 base board, you need the 12500 GPS sensor. It is supported via I2C on slot B for firmware versions 1.49 and above.
Flashing the firmware is a simple process. Connect your device via USB, click the reset button twice, and a drive will appear. On Windows, Linux, or Mac, drag the appropriate .uf2 firmware file onto the root of the drive and the firmware will be updated.
There is currently no pin required to pair RAK devices via BLE.
