Review with rating of 5 out of 5 stars
V3 crkbd in Europe!
Great PCB quality. I love the muted design, it's way calmer (not as noisy) visually than the previous crkbd versions. Not flippable.
Mini-E SMD LEDs make backlight soldering a breeze.
This PCB goes great with the Keycapsss FR4 corne case also sold in this shop.

This case is only compatible with the MX version of the pcb. The Choc switches are not heigh enough to go through the 3mm top plate.For Choc i recommend the carbon plate case. The switches snap into the plate and carbon is very stiff. This carbon case is compatible with MX and Choc version. Includes: 2x Acrylic 3mm top plates 2x Acrylic 3mm bottom plates 2x Acrylic 3mm clear Oled cover (has bluish protection film) Screws and spacer (stainless steel screws with T6 Torx) Self adhesive rubber feet (clear) Photos of the completed keyboard are for demonstration purposes only (only case included).

Sockets does not include the Pins. These can be ordered separately from the Drop-Down Menu. Sockets 1x QTY includes 2pcs socket headers (for a Split-Keyboard you need 2x QTY (4pcs socket headers)) Pitch: 0.100" (2.54mm) Contact Finish: Gold Instead of the pins, you can use legs from diodes/resistors, or these needle pins. Pins Length: 0.250" (6.35mm) Diameter: 0.020" (0.51mm) Example how to use the sockets.

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.
