Nyam Flash Loader is a simple Windows program that allows you to flash STM32 microcontrollers through the UART port.
You only need a USB-UART adapter to download programs via the built-in bootloader.
Nyam Flash Loader uses DTR and RTS pins of COM-port. The DTR pin is used to set the level at the Boot0 pin of the microcontroller. The RTS pin is used to reset the microcontroller.
Nyam Flash Loader works at baudrate 115200. It is very slow. If you need more speed, you should buy an ST-Link programmer.
The connection schematic to the programmer is very simple.
