Advanced dual BLDC driver based on the RP2350 and DRV8323S ICs, designed to be controlled from a trajectory controller over RS-485, RS-422 or TTL UART. Features a compact high power design with two stacked PCBs.
It measures 100 × 62 mm and has 2 copper layers, 1.6 mm thick.
141 parts, built around the RP2354B, 74AHCT245PW, 74AHCT541PW and SN74AHCT573PWRE4. 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 spaghetti-computer/lasagna repository on GitHub, at the commit this page was made from: the board is hardware/kicad/revc/LASAGNA2354_RevC.kicad_pcb and its schematic hardware/kicad/NESPICO_Interface.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 spaghetti-computer before reusing the design.
