Boards in 5 GitHub repositories, designed in KiCad, that use the TPL7407LD by Texas Instruments (-40℃~+150℃ 1.4V 10nA 10uA 30V 500mA 500nA 5pF MOS Seven channels SOIC-16 Relay / Coil Drivers ROHS). See how each wires it, with its parts, size, README and files; the TPL7407LD’s symbol, footprint and pinout are on its own page.
kieraneglin/hexagon-art
A passive breakout board: two lever-terminal inputs, three JST XH outputs, all six conductors (RX bus, two spares, +12V, GND, +5V) paralleled straight across. No active components, no regulation, nothing to configure.
Stab-Rabbit-coding/Open-Secure-ESC
Governed by AGENTS.md. Build spec: ../README.md. Plan: Serenity-UAV docs/plans/2026-09-17-001-feat-tilt-controller-open-secure-esc-build-plan.md (U4).
Twistiee/rcm
A CAN-controlled relay driver for a car. 21 universal channels, each of which is simultaneously a low-side output and an input — so the same board builds as a relay controller or as a switch panel, decided in firmware…
drandyhaas/KiCadRoutingTools
A set of Python/Rust tools to aid routing in KiCad
