Puchi-C - Pro Micro replacement with USB-C and ATmega32U4
Please check the news board.
- Order number: KC10106
The Puchi-C is discontinued, due to it's old chip (Atmega32U) and better alternatives.
I recommend the Helios. It's a 1:1 replacement for Pro-Micro, or Puchi-C, with more memory and ESD protection.
The new Puchi-C Rev2 has castellated holes and is even lower (3.3mm). To make the Puchi-C low as possible, the reset button has been removed.
Incorrect silkscreen labeling with this batch: Short edge connector D7 is B7
Due to the chip shortage, the price for the Atmega32u4 chip has tripled. That is why I had to raise the price.
- Compatible with all Pro Micro based PCB's
- Works with USB-A to USB-C and USB-C to USB-C cable
- ATmega32u4 controller
- Running at 16MHz and 5V
- USB-C connector (mid-mounted)
- DFU bootloader
- 5 additional ATmega32u4 pins and USB pins broken out
- Blue power led
- 24 IO pins, +5 pins (see pinout diagram for front and back view)
The Puchi-C comes without header pins, to keep the price low as possible.
I highly reccommend to use the "Single Row Sockets" from Mill-Max, the cheaper alternative, or the "Spring-loaded pin headers".
You can find the standard pin header here.

Stylish Elite-C alternative
I'm not too versed with MCUs, but this one has it all. Great design, mid-mounted USB-C port for low profile and you can use it anywhere you could have used Pro Micro or Elite-C, at a very competitive price.
Also works in conjunction with Pro Micros (on split keyboards) effortlessly, as expected.
