MxLEDBit Single Switch PCB - MX Choc Hot Swap Socket
Description
Variant
| Variant | Single PCB Qty | Switch | Kailh Hot Swap Socket | Switch LED | Diode |
|---|---|---|---|---|---|
| Choc | 25 | Choc V1 (no V2) | No | SK6812 Mini-E | SOD-123 |
| MX | 25 | MX switches and clones | No | SK6812 Mini-E | Through-Hole, SOD-123* |
| MX (Hot Swap) | 25 | MX switches and clones | Yes | SK6812 Mini-E | Through-Hole, SOD-123* |
| Pro Micro | 1 | - | - | - | - |
* If you use a SOD-123 diode, one pad will be shared with the through-hole hole due to space limitations.
- Pro Micro PCB has pins for a reset switch, I2C oled display, TRRS jack (for split keyboards) and of course the pro micro or similiar MCUs like Helios
- Grid Spacing: 19.05mm
- LeadFree HASL PCB surface finish
Pinout
The example in the photo is the MX variant, but the others are similar.
- C: Horizontal line (Column)
- R: Vertical line (Row)
- DI: LED control signal input (Data In)
- DO: LED control signal output (Data Out)
- -: Ground (for LED)
- +: VCC (5V for LED)

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.
