This Eurorack module is a hand-solderable 4hp version of Hagiwo's Clock Sync LFO. It is based on the schematics and design by mzuelch but adds a couple of buttons and an extra LED.
Sync is an open-source printed circuit board by jimmerricks, from the jimmerricks/synchroniser repository on GitHub. It is a 2-layer board of 19.2 × 106 mm with 54 parts on 52 nets, routed with 388 tracks and 42 vias.
It is built around the TL072 and BAV99,215-JSM. Its parts include 22 resistors, 13 capacitors, 9 connectors, 5 diodes and 2 ICs. It belongs with the AVR (ATmega, ATtiny) boards of this library.
This Eurorack module is a hand-solderable 4hp version of Hagiwo's Clock Sync LFO. It is based on the schematics and design by mzuelch but adds a couple of buttons and an extra LED. It is Arduino Nano based and compatible with firmware released by mzuelch, awonak and Modulove.
Use the ibom to assist with sourcing components, and as a placement guide when building the module.

It measures 19.2 × 106 mm and has 2 copper layers, 1.6 mm thick.
54 parts, built around the TL072 and BAV99,215-JSM. 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 jimmerricks/synchroniser repository on GitHub, at the commit this page was made from: the board is pcb/sync.kicad_pcb and its schematic pcb/sync.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 jimmerricks before reusing the design.
