PCB is used to control 3 typical CPU fans with mounted high-power LED chips according to temperature and tach sensors
Relays are used to power-off LED drivers in case of fan failure or overtemperature condition

Simple STM32 SWD programmer. It is based on the original ST-Link, but has only a 2-wire SWD interface. Works fine with STM32 ST-Link Utility and using original ST-Link firmware.
-first flash attached bin
-then update firmware under ST-Link Utility
