This cable allows writing firmware to an AVR microcontroller that uses UPDI, such as the new 0-series and 1-series ATtiny, or 0-series ATmega chips. It uses a USB-UART chip, using the one-wire scheme. This is compatible with
pyupdi python program, for example. It connects RX directly to the target UPDI, and TX via a 4.7k resistor.
I needed a cable like this for developing on the ATtiny814, using my new development board.
Besides this cable, there don't appear to be any maker-oriented UPDI programming products. This cable allows easy use of UPDI to write firmware onto AVR chips.
