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
(still work in progress, not fully tested)
A smart MIDI box based on a STM32 "blue pill" microcontroller (STM32F103C8T6).
Software is hosted on Github: https://github.com/retro16/MidiBox
Uses a HD44780 16x2 LCD screen with the usual I2C converter.
The interface is made of 4 push buttons arranged in a directional pad (up, down, left, right).
A SD card can be attached for more features.
Schematic to test CAN bus (Controller area network) between Jetson TX2 and STM32.
