README
README.mdKeebDeck Basic
An affordable handheld QWERTY USB keyboard with a silicone keypad.
This is our first product using our KeebDeck Keyboard, meant to be a cost-effective way to demonstrate the capabilities of the Keyboard. It exposes the key presses as a USB HID over USB Type-C. The board also includes an unpopulated Qwiic connector footprint on the back, and test points with an I2C interface compatible with our previous BBQ10/BBQ20 boards.

What parts does the Keebdeck basic use?
120 parts, built around the AP3032KTR-G1, AP2112K-3.3 and LTW-010DCG-SR-G. 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 Keebdeck basic KiCad files?
From the solderparty/keebdeck_basic_hw repository on GitHub, at the commit this page was made from: the board is keebdeck_basic.kicad_pcb and its schematic keebdeck_basic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keebdeck basic design in my own project?
Its repository states no licence, so its author keeps all rights: ask solderparty before reusing the design.
