Its parts include 35 switches and 2 ICs. It belongs with the keyboards and input boards and the RP2040 boards of this library.
README
README.mdOstrich
34 key keyboard based on RP2040 with canted MCU.
This keyboard was inspired by the Reviung34 keyboard.
You can find the qmk firmware here
If you are interested in using VIAL instead, (This is a GUI for qmk). Then please go here
It is important to note, the 0.9 version of this keyboard keyboard is built with an mcp23017-e/so MCP chip instead of using diodes.
This chip requires pull-up resistors. Since this was meant to use an OLED, it just borrows the one built into the SSD1306. If you decide you don't want an OLED, you will need to solder pull up resistors on GP0 and GP1. (4.7k have been sufficient in my testing)
If you are using the 1.0 or later versions of this keyboard, the keyboards will use diodes, and you won't have to worry about it.

Questions
How big is the Ostrich PCB?
It measures 217.1 × 130.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ostrich use?
40 parts. 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 Ostrich KiCad files?
From the doesntfazer/Ostrich repository on GitHub, at the commit this page was made from: the board is Ostrich PCB/rev0.9-mcp23017/Ostrich.kicad_pcb and its schematic Ostrich PCB/rev0.9-mcp23017/Ostrich.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ostrich design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
