Altium STM32 Hardware Design - An Overview in Under 20 Minutes - Phil's Lab #38

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.
