Overview
Starboard is an open-source printed circuit board by deveworld, from the deveworld/starboard repository on GitHub. It is a 2-layer board of 63 × 63 mm with 21 parts on 26 nets, routed with 126 tracks and 4 vias.
It is built around the SK6812MINI-E. Its parts include 12 diodes, 7 switches, 1 IC and 1 connector. It belongs with the keyboards and input and lEDs and displays boards and the RP2040 boards of this library.
Main components
1README
README.mdStarboard
Starboard is a compact Hackpad macropad using only kit parts: six MX-style switches, one EC11 encoder, one 0.91 inch OLED, six SK6812 MINI-E LEDs, and a Seeed XIAO RP2040.

Firmware
- QMK source:
Firmware/qmk/starboard/ - Production archive:
production/firmware-qmk.zip - Prebuilt UF2:
production/firmware.uf2 - Build command:
qmk compile -kb starboard -km default - Features: 6-key matrix, encoder rotation, encoder press, SSD1306 OLED, SK6812 RGB lighting
- Configurator: https://deveworld.github.io/starboard/configure/ remaps keys and the encoder, sets lighting, writes custom OLED text and records macros over WebHID (Chrome/Edge). The firmware speaks the VIA protocol, with OLED settings on VIA's custom channel.
- Flashing an assembled board: hold FN (bottom-right key) and press the top-left key to enter the bootloader, then copy the UF2 onto the
RPI-RP2drive. - Wireless note: the current XIAO RP2040 hardware has no BLE radio; ZMK wireless should be reserved for a future BLE-controller revision.

Verification
- ERC: 0 errors, 6 symbol-library mismatch warnings for SK6812 cache copies.
- DRC: 0 errors, 0 unconnected pads, 0 schematic parity issues; remaining warnings are silkscreen/cosmetic.
- Case V5 fit audit: all boolean clash and clearance checks pass.
- Firmware package:

Questions
How big is the Starboard PCB?
It measures 63 × 63 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Starboard use?
21 parts, built around the SK6812MINI-E. 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 Starboard KiCad files?
From the deveworld/starboard repository on GitHub, at the commit this page was made from: the board is PCB/starboard.kicad_pcb and its schematic PCB/starboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Starboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask deveworld before reusing the design.
