Features

Supports different MCU Boards to interact with Minicaps and a Radio Board.

BoM

Just female pin headers.

Errata

• GPIO texts on silk screen are missing GPIO 4-6.
• Radio TX/RX are swapped.
• [Solar harvester] Base Board pin GPIO7 should be also connected to Radio Board v2 pin 10 in CN2 connector.
• [Solar harvester] Base Board pin DAC1 should be also connected to Radio Board v2 pin 9 in CN1 connector.
