L0005-Valve Controller
SunDevilRocketry/Valve-Controller
Controller for managing the liquid engine's solenoid valves and servo-actuated ball valves.

The solenoid driver uses solid state relays to allow an Arduino Mega to control AC powered solenoids with a 5V control signal. The board is used by the SDR Hybrid Propulsion team to control their Pancake engine's pressurization and main oxidizer valves.
H0001-Solenoid Driver is an open-source printed circuit board by SunDevilRocketry, from the SunDevilRocketry/Solenoid-Driver repository on GitHub. It is a 2-layer board of 75.2 × 35.4 mm with 19 parts on 20 nets, routed with 92 tracks and 2 vias.
It is built around the AQH0223AX and 0678L9100-02. Its parts include 4 resistors, 4 connectors, 2 capacitors, 2 switches and 1 fuse.

19 parts, built around the AQH0223AX and 0678L9100-02. 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 SunDevilRocketry/Solenoid-Driver repository on GitHub, at the commit this page was made from: the board is src/H0001-Solenoid-Driver/H0001-Solenoid-Driver.kicad_pcb and its schematic src/H0001-Solenoid-Driver/H0001-Solenoid-Driver.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 SunDevilRocketry before reusing the design.
