40 Pin GPIO
The full Raspberry Pi 40 pin GPIO is available through pads on the main board. Please note that there are some specific changes implemented that may cause issues with some hats. The UART is normally connected to the flight controller (if jumper fitted) and the I2C lines have been used for dual cameras. For more information see
Please orient using the silk screen. Designed for a 40 pin FPC 0.5mm pitch connector (not populated). Manufacturer: HDGC, Part Number: 0.5K-A-40PB, LCSC Part Number: C2914160.

If you are using a CBU-CM405-FC-ESC-**** Board it will cover the pads and make them not accessible. If you require use of the GPIO please use the CBU-CM405-BO which will leave them exposed.
