Overview
Euklick is an open-source printed circuit board by jrlomas, from the jrlomas/euklick repository on GitHub. It is a 2-layer board of 27 × 17 mm with 9 parts on 6 nets, routed with 47 tracks and 1 via.
It is built around the B3B-XH-A(LF)(SN). Its parts include 3 resistors, 1 diode, 1 connector and 1 switch. It belongs with the sensors and measurement and robots and motor control boards of this library.
Main components
1README
README.mdEuklick BETA
Single PCB 5V optical probe for 3D printers. Euklick is meant to work with the new Omron optical microswitches of the D2FP series, specifically the D2FP-FN2. This switch is rated to a minimum of 70,000,000 operations, and much tighter tolerances at the time the switch is pressed.
The PCB, standing on the shoulder of giants
The PCB borrows, known euphemistically in the music industry as sampling, from the designs of the Euclid probe and PCBKlicky. Unlike PCBKlicky, however, to lower the cost and streamline ordering boards from manufacturers, it makes use of a single board that can be used for both the microswitch (probe), and toolhead side. Although not necessary, when the board is used in its toolhead holder, the wings / leaves at the end of the board can be snapped as to provide a tighter fit to the plastic parts. There are cutouts and mouse bites that make it possible to snap the ends, with some force. The board is mostly compatible with PCBKlicky; nonetheless, the switch is slightly offset from the centerline of the PCB since the pinout for the optical switch changed from the inline package of the older D2F physical switches. This change makes it possible for the mounted magnets to avoid the soldering pads of the optical switch, while re-using the original magnet positions. Unlike PCBKlicky, the board only supports 5V as its source of power, and power is not optional (since the optical switch requires active power).

Assembly
Two of the boards have to be used for assembly. For the upper board (board attach to the toolhead), only the JST 3 pin header is necessary, along with three countersunk magnets. Optionally, the wings on the board can be snapped along the provided mouse bites line.
For the lower board the switch should be attached from the side marked S1 as here, and the rear of the board should be populated

Questions
How big is the Euklick PCB?
It measures 27 × 17 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Euklick use?
9 parts, built around the B3B-XH-A(LF)(SN). 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 Euklick KiCad files?
From the jrlomas/euklick repository on GitHub, at the commit this page was made from: the board is euklick.kicad_pcb and its schematic euklick.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Euklick design in my own project?
Its repository states no licence, so its author keeps all rights: ask jrlomas before reusing the design.
