GPS Tracker with GSM connection, logging to SDcard, sending data to mqtt server

Secure USB DFU1.1 bootloader for STM32 with STM32F4x1xE target fully compatible to STM32duino and PlatformIO

Example code of USB Host, USB Hub for STM32F401 with PlatformIO, STM Cube framework

Playing streaming video (motion jpeg). The server (computer) continuously takes screenshots of the desktop, encodes them in jpeg and transmits via VCP them to the client (microcontroller). The microcontroller decodes the image and displays it on the display.

This one is a full open design (electronics, pcb and firmware) of a PS/2 Keyboard adapter with USB console for use in MSX and other legacy computers - 15x8 matrix(BCD input - 8 bits "Low active" output).
