Last updated 1 year ago

On the bottom side of the board are 2 micro SD card slots.

(Red) Is connected to the STM32F405 for flight data logging/LUA storage.

(Blue) Is used when a CM4 "Lite" model is used, and should be flashed with the desired OS. If using a CM4 with EMMC ensure there is no SD card fitted.
