Sea-Picro by joshajohnson
Sea-Picro is a RP2040 based board in the Arduino Pro Micro form factor.
Features
* Compatiable with most pro micro based keyboards
* RP2040 microcontroller, with dual M0+ processors at up to 133MHz
* Mid mount USB-C connector, which is low profile and can't be ripped off
* Optional Elite-C style pinout, adding an additional 5 IO for large keyboards
* Single button reset / bootloader circuit which changes behavior based on how long it's held (RP2040 usually requires two buttons to flash new firmware, making it challenging when installed upside down in a keyboard)
* ROM bootloader which prevents board from being bricked
* EXT version has a 5V level shifter and extra pin to drive strings of WS2812 LEDs.
* RST version has a WS2812 LED for use with CircuitPython or as a status indicator on the RST version.
* Onboard power LED.
* IO pinout identical to the Sparkfun RP2040 Pro Micro

0xCB-Helios by 0xCB-dev
The 0xCB Helios is an Elite-C compatible MicroController that is based on the RP2040
Helios has 16MB(128Mbit) of flash, Dual ARM Cortex-M0 @ 133MHz, and 264kB SRAM. It features a default off red power LED, a blue user LED, and a level-shifter to drive 5V components. Helios has an ESD protection chip onboard, supports VBUS detection for split keyboards, and you can select VBUS instead of raw for the 5V pin to hook up an external USB port with the included D+ and D- pads while maintaining ESD protection. Another huge advantage is the single button reset circuit which enables you to reset the board with a short click and enter the bootloader with a long (>500ms) click. This backwards compatiblility also enables you to use reset buttons on existing keyboards for both functions. The bootloader is unbrickable as its located in ROM on the rp2040 itself.

NINE by bsag (but she's a girl)
The Nine is a tiny 18-key split, wireless, ergonomic split keyboard, heavily inspired by Ben Vallack's Piano 2. I tried out his design and loved it, but wanted to tweak the physical layout a bit to fit my hands and my use case better. It uses Nice!Nano V2 BLE-equipped controllers, and (optionally) Nice!View displays to show information like the connected BLE profile, battery level and layer name. You can read more about this keyboard and the design decisions I made here: Introducing the Nine keyboard and Nine keyboard Part 2 - the case.

Alvaro v1.5 by Ariamelon
Pro Micro-compatible 32u4 Breakout Board. This board is a heavily-modified Goldfish Rev. C. While the schematic, basic layout, pinout (of course) etc is essentially the same, it uses 0603 components instead of 0402 and has some other changes.
Features
* Mid-mount USB-C connector using a low-profile USB C 2.0 connector.
* Pin-compatible with the original Pro Micro.
* 5 extra pins on the bottom like the Elite-C and Goldfish.
* Exposed USB data lines on 2.54mm grid.
* Easier to solder than the Goldfish.
* Has fuse unlike Goldfish.
* On-board power LED.
* Fully hand-solderable.

Probably one of the cheapest split keyboards you can build.
This is the result of really enjoying building keyboards, but not wanting to spend that much money on it. The pcb is reversible, connected using rj45, and utilizes a japanese duplex matrix, so only one mcu is needed (in fact it only uses 7 of the rj45 wires to support 18 switches and an encoder on the right side).
