RunTheBot/NotAHackPadBasically a hack pad but with a lot more keys and a lot more LEDs.
Hack pad is an open-source printed circuit board by RunTheBot, from the RunTheBot/NotAHackPad repository on GitHub. It is a 2-layer board of 192 × 217 mm with 416 parts on 241 nets, routed with 1,694 tracks and 155 vias.
It is built around the SK6812MINI-E, IRF9540NS and IRLZ44N, with the BSS138 among its other parts. Its parts include 201 diodes, 100 capacitors, 100 switches, 5 transistors and 2 resistors. It belongs with the RP2040 boards of this library.
Basically a hack pad but with a lot more keys and a lot more LEDs.
Made because a hackpad was too easy and small. Also I wanted to make it more like a keyboard than a hackpad. I also wanted to use a full pico.

The 413 most common of 416 parts.
It measures 192 × 217 mm and has 2 copper layers, 1.6 mm thick.
416 parts, built around the SK6812MINI-E, IRF9540NS, IRLZ44N and BSS138. 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.
From the RunTheBot/NotAHackPad repository on GitHub, at the commit this page was made from: the board is pcb/hack_pad.kicad_pcb and its schematic pcb/hack_pad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask RunTheBot before reusing the design.
