## Description

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 :)
