Overview
Optical tachometer hardware is an open-source printed circuit board by jaylamb, from the jaylamb/optical_tachometer_hardware repository on GitHub, published under the Apache-2.0 licence. It is a 2-layer board of 21 × 24 mm with 11 parts on 7 nets, routed with 23 tracks and 3 vias.
It is built around the TCRT5000. Its parts include 4 resistors, 3 diodes, 1 capacitor, 1 transistor and 1 connector. It belongs with the sensors and measurement boards of this library.
Main components
1README
README.mdOptical Tachometer Hardware
The optical_tachometer_hardware project consists of a single printed circuit board (PCB)
which contains a TCRT5000 reflective sensor and its supporting circuitry. The device's
physical interface is a three position right-angle pin header.
Usage
Built-up hardware is a sensor module designed to be interfaced with a General Purpose Input/Output (GPIO) pin on a microcontroller. The sensor is active-high, and asserts its output when in close proximity to a reflective object.

Questions
How big is the Optical tachometer hardware PCB?
It measures 21 × 24 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Optical tachometer hardware use?
11 parts, built around the TCRT5000. 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 Optical tachometer hardware KiCad files?
From the jaylamb/optical_tachometer_hardware repository on GitHub, at the commit this page was made from: the board is optical_tachometer_hardware.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Optical tachometer hardware design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
