Look no further, this is what you need if you work with ESP and similar MCU or the new attiny/atmega chips with UPDI programming.
Using USB-C to connect to your PC this is a USB to UART converter based on CH340 which doubles as SerialUPDI programmer. A switch selects function (ESP or UPDI programming) and second switch target voltage (1.8-3.3-5V 500mA max or Target self powered in the same range).
Only 50x15mm this is a small low cost and handy tool for everybody :)
