A pro micro alternative with a durable USB-C port and a DFU bootlaoder!

Features:

• Compatible with all Pro Micro-based PCBs

• Mid mount USB-C port that can’t be ripped off

• ATmega32u4 controller

• DFU bootloader

• 6 additional ATmega32u4 pins and USB pins broken out

• On-board reset button (you can still use the reset button on the keyboard PCB if it has one)

• 1.0mm thick PCB for slimmer profile (don’t worry, it’s still very solid and doesn’t flex)

• Comes with two 12-pin headers and one 5-pin header

• Total of 24 I/O pins to work with (6 more than the Pro Micro)

Changes in v4:

• Mid-mount USB-C port (lower profile overall)

• broken-out VBUS pin (above the existing 'PB0' pin) allows the easier use of an external USB port if desired

• Low-profile Reset Switch (shorter than the current one so it lies below the profile of the USB-C port)

This board can be used for just the master half of a split keyboard (corne, lily, helix, etc…) and then a cheaper pro micro on the slave side to save some money!
