Overview of how to design an STM32-based PCB including various peripherals (SD card, USB) and some sensors (IMU and barometric pressure sensor). Including information on how to order these PCBs fully-assembled from JLCPCB. This board will be used in future videos on signal processing, STM32 firmware, and more - and is an upgrade on the original ’LittleBrain’ PCB. Hardware designed using Altium Designer.
