Overview

Keyboard is an open-source printed circuit board by NEOgHacking, from the NEOgHacking/Keyboadr repository on GitHub. It is a 2-layer board of 433.4 × 118.8 mm with 294 parts on 183 nets, routed with 1,233 tracks and 86 vias.

It is built around the RP2354B, AP7361C-33E and USBLC6-2SC6, with the ABM8-272-T3 and DSK24L among its other parts. Its parts include 107 switches, 105 diodes, 19 capacitors, 8 resistors and 4 connectors. It belongs with the keyboards and input boards and the RP2350 boards of this library.

Very quick made keyboadr for blueprint 3 days before!

So this keyboadr was made by me and it was decided this project would be made 3 days before the end date of blueprint. Its a 100% keyboard with 2 displays and a rotary encoder. It uses a custom rp2354B build in as the processor. This has been made in a very constrainged time with a custom rp2354B implementation as a controller. It uses simple 0.91 inch displays and a rotary encoder.

Questions

How big is the Keyboard PCB?

It measures 433.4 × 118.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Keyboard use?

294 parts, built around the RP2354B, AP7361C-33E, USBLC6-2SC6 and ABM8-272-T3. 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 Keyboard KiCad files?

From the NEOgHacking/Keyboadr repository on GitHub, at the commit this page was made from: the board is PCB/Keyboard.kicad_pcb and its schematic PCB/Keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Keyboard design in my own project?

Its repository states no licence, so its author keeps all rights: ask NEOgHacking before reusing the design.
