EwoudVV/arpeggiator
12-note analog arpeggiator with a 1/2/3 octave range, custom pcb and printed case




It measures 90 × 90 mm and has 2 copper layers, 1.6 mm thick.
80 parts, built around the UCC27321P, UCC27322P, 74HC14 and 74HC74D. 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 MrSimranjitSingh/AcMains_TC repository on GitHub, at the commit this page was made from: the board is kiCAD_files/sstc_drsstc_driver/sstc_drsstc_driver.kicad_pcb and its schematic kiCAD_files/sstc_drsstc_driver/power.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
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).
