This thing is about to appear on Crowd Supply

Improved version of the original design.

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

With such "amazing" features as:

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.

Slots 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.
