Product information "Puchi-C - Pro Micro replacement with USB-C and ATmega32U4"

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.

The SparkFun Pro Micro RP2040 is a low-cost, high performance board with flexible digital interfaces featuring the Raspberry Pi Foundation's RP2040 microcontroller. Besides the good 'ol Pro Micro footprint, the board also includes a WS2812B addressable LED, boot button, reset button, Qwiic connector, USB-C, resettable PTC fuse, and castellated pads. The RP2040 utilizes dual ARM Cortex-M0+ processors (up to 133MHz) and features: 264kB of embedded SRAM in six banks Six dedicated IO for SPI Flash (supporting XIP) 30 multifunction GPIO Dedicated hardware for commonly used peripherals Programmable IO for extended peripheral support Four channel ADC with internal temperature sensor, 0.5 MSa/s, 12-bit conversion USB 1.1 Host/Device The RP2040 is supported with both C/C++ and MicroPython cross-platform development environments, including easy access to runtime debugging. It has UF2 boot and floating-point routines baked into the chip. The built-in USB can act as both device and host. It has two symmetric cores and high internal bandwidth, making it useful for signal processing and video. While the chip has a large amount of internal RAM, the board includes an additional 16MB external QSPI flash chip to store program code.
