I use the Glu-MCU as a better replacement for Arduino pro mini boards
The Atmega328 or Atmega32U4 boards nowadays are either hard to get or expensive. And the microcontroller is kinda old.
That's why I decided to make a nice and simple alternative board with the much more powerful AVR64DD32 microcontroller.
There is not much on this board, only the necessities. For programming the UPDI is broken out on the top of the PCB. There is a resistor on the PCB as well so you can connect it directly to any TTL USB serial converter. For programming connect VDD to 3,3V or 5V, GND to GND, OUT to the Rx and IN to the Tx of the serial converter. pymcuprog can program the device in a few seconds.
On the photo I already connected a 4 pin header to VDD, GND, A0 and A1, I use it for debugging via serial. The pin A0 is the standard Tx pin and A1 is the standard Rx pin of USART0.
