This is an open source wireless controller for the Kinesis Advantage and Advantage 2 (see below) line of keyboards using the BlueMicro firmware.
Firmware can be found here. https://github.com/wizarddata/BlueMicro_BLE/tree/blue-wizard-working
For now, use the fork linked above to make any layout changes and utilize the adafruit nrf52832 BSP.
Gerbers and BOM are available if you'd like to build your own!
You will need some additional hardware to make your board functional. Links are provided below for guidance:
- Latching/Toggle/Rocker panel mount switch for power, or bridge J14 pins for always on.

Advantage 2 Troubleshooting
Some keyboards experience intermittent joined activations on function keys. Installing a jumper wire from the negative battery connection to the ground pin of the 3.3v regulator can help resolve this issue. The necessary wire is pictured here:
Some users have reported F1 simultateously triggering F2. A 10k resistor between the pins indicated here will resolve this.

Questions
How big is the Blue Wizard PCB?
It measures 108 × 95.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Blue Wizard use?
47 parts, built around the BMD-300-A-R, CP2104EK, MCP73831T-2ACI/OT-HXY and MIC5504-3.3YM5. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Blue Wizard KiCad files?
From the wizarddata/Blue-Wizard-Mod repository on GitHub, at the commit this page was made from: the board is Blue_Wizard/Blue_Wizard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Blue Wizard design in my own project?
Its repository states no licence, so its author keeps all rights: ask wizarddata before reusing the design.
