So, have you read about the v2.1 Rock On? Click here to read that first.
Now, let’s note the differences below:
- New features:
- Trackball support!
- 3 more keys at the bottom center
- 1 additional encoder at the bottom center
- Pimoroni Haptic Feedback (v3.1 only)
- Audio support (v3.1 only, pre-soldered on board)
- Removed features:
- Pimoroni trackball
- OLED
To make this a complete kit, remember to also add:
- One of the following cases:
- Rock On 3DP Case V2 (MX and cirque support)
- Rock On 3DP Case V2 low profile (MX or Choc, and cirque support)
- Rock On 3DP Case V3 (for trackball support)
- Note that these cases are available for printing yourself, found here in the fingerpunch github repo.
- hotswap sockets (7 sets)
Optional components:
- cirque trackpad kit
- trackball sensor kit
- per key leds (optional, 7 sets)
- rotary encoders (optional, EC11 only)
- rotary encoder caps (optional)
- Pimoroni Haptic Feedback (v3.1 only)
Controller support:
- Nothing AVR is supported! So, do not try to use this pcb with a Pro Mico or Elite-C
- STeMCell (tested, available as an add on)
- Splinky (untested, but should work)
- KB2040 (untested, but should work)
- Blok (untested, but should work)
- nice!nano for wireless
- untested, but by request, I’ll write the ZMK firmware for you. Note that this will not support the trackpad or trackball as they aren’t supported in ZMK as of this writing (2022-10-07)
Important notes:
- If you are using a nice!nano for this build, you cannot use the center rotary encoder. There is enough gpio on an elite-c equivalent, but not on the nice!nano
- If you use a controller with a Pro Micro compatible footprint (as opposed to an Elite-C compatible footprint), you cannot use any rotary encoders
- Examples of Pro Micro compatible footprints: KB2040, Blok
- Examples of Elite-C compatible footprints: STeMCell, Splinky
