Overview
Relay driver shield is an open-source printed circuit board by njh, from the njh/relay-driver-shield repository on GitHub, published under the CC-BY-SA-4.0 licence. It is a 2-layer board with 21 parts on 14 nets, routed with 77 tracks and 0 vias.
Its parts include 8 resistors, 4 diodes, 4 transistors and 4 connectors. It belongs with the home automation and IoT and microcontroller boards boards and the AVR (ATmega, ATtiny) boards of this library.
README
README.mdRelay Driver Shield
An Arduino shield for controlling four 12v relays. The schematic and PCB layout were created using KiCad.
While it is designed for relays, it can be used for powering anything that requires a bit more current or voltage.
| Arduino Pin | Function |
|---|---|
D5 | Relay 1 |
D6 | Relay 2 |
D7 | Relay 3 |
D8 | Relay 4 |
The output voltage is determined by the input voltage on the Arduino Board - the VIN pin.

Questions
What parts does the Relay driver shield use?
21 parts. 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.
Where can I download the Relay driver shield KiCad files?
From the njh/relay-driver-shield repository on GitHub, at the commit this page was made from: the board is relay-driver-shield.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Relay driver shield design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
