Frood by piit79

The Frood is a high-performance and affordable Pro Micro drop-in replacement based on a Raspberry Pi RP2040. It is physically and electrically compatible with Elite-C/nice!nano as much as possible.

Features
* Powerful dual-core Raspberry Pi RP2040 MCU
* 2 MB on-board QSPI flash memory
* Only 3.2 mm thick thanks to a mid-mounted USB-C socket
* 500 mA linear regulator and resettable fuse
* Combined Pro Micro / Elite-C / nice!nano / SparkFun Pro Micro RP2040 compatible pinout
* 5 more I/O pins (GPIO12-GPIO16) added along the bottom edge
* 23 available digital pins for a maximum of 11x12 = 132 switches
* 4 pins configurable as analogue inputs
* USB D+/D- broken out for use with an external USB socket/daughterboard
* USB power sensing on GPIO19 for split keyboard side detection
* UF2 bootloader for drag & drop programming with no extra software required
* Orange indicator LED on pin GPIO17

AMBER CHOC Switch

We are (https://junkfoodarcades.com/) working with KailhSwitch to build a new low-profile switch with a new level of performance at just 1mm of pre-travel!

MUCH faster actuation than most other speed focused competitors in a CHOC form factor.

Currently in design so the color choices may change but we are calling it the AMBER switch and it will be exclusive to us! Look for it this summer!

CFX BoW Update

We wanted a cleaner and crisper appearance for our BoW keycaps. So we have decided to use a brighter white for BoW.

In comparison, the 1U White blanks are more yellowish-white. The difference is more noticeable on the actual product.

We will be adjusting the 1U white's color to match the BoW for the next batch.

Lapa by lemosbor

Lapa (Russian: Лапа, paw) - split keyboard-mouse with 36 keys (40%) for typing without moving the hands.

Features
* The wrist-rest is part of the keyboard and is located above the main row keys.
* The built-in mouse sensor allows you not to transfer your hand from the keyboard to the mouse.
* The thumb keys are located on a separate part of the case, much higher than other keys.
* The keys of each finger are located on several circles of different diameters, forming a "stairs". This solution provides maximum perpendicularity of the keystroke vectors to the key surfaces.
* Minimum height. The surface of the lowest key is at a distance of 2 cm from the table.
* The keycaps are flush with the body.
* Replaceable oak pad for resting the wrist.
* Reliable russian connector РШ2Н-1-6 for connecting two halves of the keyboard.
* Magnets to connect the two halves of the keyboard for transporting.

Epi 32U4 by rallekralle11

Named after the Epipactis genus or orchids. The flower of one appears on the board.

Features
* USB power and data line ESD protection as well as power filtration and a fuse.
* Crenellated pins.
* No integrated voltage converter, only runs at 4,5-5,5v (down to 2,7 if you make it with an 8mhz crystal, or use the internal oscillator).
* USB-C connector sunk into the board, and slighly portruding from the end for panel mounting.
* 1,27mm pin spacing.
* Extra pins broken out.
* Holes where M2 bolts can be used to hold it in place.
* No rx/tx/power LEDs. Only one on pin 13 for testing.
* Includes some custom footprints with 3D models.
