Overview
Mirror controller is an open-source printed circuit board by VikramR3, from the VikramR3/Mirror_controller repository on GitHub, published under the MIT licence. It is a 2-layer board of 71.9 × 43.8 mm with 16 parts on 13 nets, routed with 85 tracks and 1 via.
It is built around the IRF9540NS and SMBJ15A. Its parts include 5 connectors, 3 diodes, 2 capacitors, 2 resistors and 2 fuses. It belongs with the robots and motor control and lEDs and displays boards of this library.
Main components
2README
README.mdMirror Controller
A 2-layer 12 V board that touch-switches an LED strip and drives a linear actuator in both directions: a latching touch module energises a DPDT relay wired as a polarity reverser, so one touch extends the actuator and the next retracts it. Mains is kept off-board deliberately, so nothing on the PCB exceeds 12 V. Designed in KiCad.

Questions
How big is the Mirror controller PCB?
It measures 71.9 × 43.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mirror controller use?
16 parts, built around the IRF9540NS and SMBJ15A. 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 Mirror controller KiCad files?
From the VikramR3/Mirror_controller repository on GitHub, at the commit this page was made from: the board is Mirror_controller.kicad_pcb and its schematic Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mirror controller design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
