jer-lil/tremolo-hardwareThis is the hardware (PCB, MCAD) design for a tremolo pedal for guitar (or bass, synth, tonewheel organ, whatever you like). The firmware is here: https://github.com/jer-lil/tremolo-firmware/tree/main
Digital Board Rev 1 is an open-source printed circuit board by jer-lil, from the jer-lil/tremolo-hardware repository on GitHub. It is a 4-layer board of 101.6 × 101.6 mm with 135 parts on 130 nets, routed with 1,364 tracks and 96 vias.
It is built around the FT230XS-R, CPC1017N and MCP42050-E/P, with the NCP1117LPST33T3G-MS among its other parts. Its parts include 24 capacitors, 23 resistors, 15 ICs, 14 connectors and 9 diodes. It belongs with the audio and music boards and the STM32 boards of this library.

This tremolo packs a lot of features into a very small (Hammond 125B, 65x120mm) enclosure. Features include:
Note that at the time of writing, this project is still in progress. As such, I have not been focusing on public documentation. If you have questions, please reach out.

darshp848/bldc-controller-60v
60 V, 20 A / 80 A peak BLDC motor controller that fits the MD80 v3.0 mounting. KiCad 10, 6 layers.
It measures 101.6 × 101.6 mm and has 4 copper layers, 1.6 mm thick.
135 parts, built around the FT230XS-R, CPC1017N, MCP42050-E/P and NCP1117LPST33T3G-MS. 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 jer-lil/tremolo-hardware repository on GitHub, at the commit this page was made from: the board is Rev_1/Digital_Board_Rev_1/Digital_Board_Rev_1.kicad_pcb and its schematic Rev_1/AnalogBoard_Rev0/AnalogBoard_Rev0.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 jer-lil before reusing the design.
