In light of putting together the VIK specification, this is a nrf52840 pro micro footprint controller that has a built in VIK connector. This means wireless via bluetooth and VIK support.
Features:
- nRF52840
- 5V access on VIK connector, either via VBUS (wired only) or a DC-DC step up converter (wireless)
- Note that soldering the jumper for the step up will drain a significant amount more battery, so please only use it with a sufficiently large battery (1000+ mAh recommended)
- Also note that you don’t need 5v for most VIK modules. The only modules that currently use 5V are the haptic, pmw3360 modules, and any leds on the VIK modules
- Mid mount USB-C
- Pro Micro footprint
- VIK connector
- The rest of the features are documented in the mikoto repository
Firmware support:
- ZMK
- See readme at https://github.com/sadekbaroudi/zmk-fingerpunch-controllers
- Controller firmware: https://github.com/sadekbaroudi/zmk-fingerpunch-controllers/tree/main/boards/arm/vikoto
- Example usage: https://github.com/sadekbaroudi/zmk-fingerpunch-keyboards
- The pinout is defined in the controller firmware above
- The VIK pinout is in vik_connector.dtsi
- The through hole pinout is in arduino_pro_micro_pins.dtsi in the gpio-map
