cookiemonsternz/Eurorack-DIGI
DIGI utilises an ice40UP5K fpga chip, featuring 5280 luts and a 48Mhz clock. This is accompanied by a USB-SPI interface for easy programming.


It measures 120.5 × 46 mm and has 2 copper layers, 1.09 mm thick.
192 parts, built around the EFM32PG23B200F512IM40-C, AP63200WU, AT25XE321D-UUN-T and TPS62171DSG. 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 Alzymologist/Kampela repository on GitHub, at the commit this page was made from: the board is hardware/development/Kampela_E1/Kampela_E1.kicad_pcb and its schematic hardware/development/Kampela_A1/CoilDisp.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).
