Revision 2 of the board that's a tribute to one of the greatest players ever, the BDN9 is a fun little 3x3 macropad that lets you try out a few rotary encoders as well. What can you do with rotary encoders? That's for you to figure out! Use it as up/down, page up/down, volume control, or whatever, get creative. Go win a Super Bowl with it or something.
With Rev. 2, the microcontroller and other components are already soldered on.
Note: PCB is sold separately from the plates/cases. You will either need to purchase the FR4 Plate kit or one of the Acrylic cases to go along with the PCB.
Features:
- 3x3 grid of keys
- Ability to add up 3 rotary encoders on the top row of the board
- In-switch RGB LEDs and two underglow RGB LEDs
- STM32F072 microcontroller
- Mid-mount USB-C port for lower profile build
- MX/Alps/Choc switch support
PCB Includes:
FR4 Plate Kit:
- 1 FR4 Switch plate
- 1 FR4 Bottom plate
- 8 4mm M2 screws and 4 6mm M2 standoffs
Acrylic Cases (requires PCB):
For use with MX-compatible switches only.
Not compatible with Rev. 1 PCBs, unless all pins poking through top side of PCBs are flush and don’t stick out.
Includes:
- 5mm thick black acrylic switch plate
- 5mm thick black acrylic bottom plate
- 8mm thick clear acrylic middle layer
- 8 8mm M2 screws
- 4 7mm M2 standoffs
Optional Acrylic Mid Layer (requires plates):
Just the middle layer from the Acrylic Case kit above that can be used with the FR4 plates. Goes between the switch plate and bottom plate. Only compatible with Rev. 2 BDN9.
Includes:
- 4 7mm standoffs (needed to replace ones that are longer than the thickness of the mid layer)
- 8mm thick clear acrylic middle layer
