Sodar is a semester project exploring directional ultrasonic object detection using a custom 19-element phased array.
It measures 96.5 × 68.6 mm and has 2 copper layers, 4.69 mm thick.
44 parts, built around the TC78H621FNG,EL. 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 lucanatorvs/eZ-Green repository on GitHub, at the commit this page was made from: the board is eZ-Green-Driver/eZ-Green.kicad_pcb and its schematic eZ-E36-brakeout/eZ-E36-brakeout.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 lucanatorvs before reusing the design.
