Kailh Low-Profile version: 2.5-KLP (does not have the staggered pads like 2.7)
Note on Iris Choc/Kailh Low-Profile PCBs:
Do not use the Peel-A-Way sockets with these PCBs to socket the Pro Micro, as there is not enough clearance between the PCB and top plate. Installing the sockets will cause the sockets to hit the underside of the top plate, causing shorts.
Note: PCB Kit no longer includes LED support components to reduce price, as not everyone used these. The MOSFET and resistors for the MOSFET are available separately via the LED Support Add-on Kit.
The PCB Kit includes the following:
2 Iris PCBs
2 Push buttons for reset
2 TRRS jacks (no need to buy separately)
56 1N4148 diodes
2 4.7kΩ resistors
Each half of the board is a 4x6 matrix with the same vertical stagger as the Ergodox and with 3-4 thumb keys. The 2u thumb key can be replaced with 2 1u keys. The spot for the 2u has holes for Cherry PCB mounted stabilizers.
There's also a spot on the PCB for a pushbutton switch to reset the Pro Micro for flashing. No more taking a wire/tweezers/screwdriver to jump the Reset and GND pins!
Many thanks to Lewis Ridden (/u/GAMING_FACE) for coming up with this design.
Named after Iris, the goddess of the rainbow and messenger of the gods. The curvature of the top row is something like a rainbow, and keyboards are used to send messages.
