README
README.mdclops
clops is a qazlike unibody split sub40s keyboard. The KLE and firmware is by ha ha ha which itself is inspired by a KLE from Noelle. PCB is designed by Calvin0563. It sports a rp2040 and hotswap socket, and supports 1 center rotary encoder and 1 bottom row roller encoder.

Build Guide
When installing the Roller encoder be sure to remove the plastic clips where the encoder slots into the pcb cut out and make sure it is aligned to your satisfaction with the centre of the pcb before soldering!
Firmware
The firmware was written by ha ha ha and both the flash file and source code can be found in the firmware folder.
Case
protieusz has designed a 3d printable case for the clops. It can be found here:

Questions
How big is the Clops PCB?
It measures 234.5 × 96 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Clops use?
112 parts, built around the RP2040, W25Q16JVUXIQ and USBLC6-2SC6. 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 Clops KiCad files?
From the calvin-mcd/clops repository on GitHub, at the commit this page was made from: the board is Project/clops.kicad_pcb and its schematic Project/clops.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Clops 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).
