About the Toolhead PCB
Toolhead is an open source PCB design by tanaes, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 17.5 × 17 mm, with 6 components from 6 distinct parts.
By type, the board carries 2 jumpers, 2 resistors, 1 connector and 1 diode.
From the project
Based on two legends: the Klicky Probe by JosAr and the Euclid Probe
Based on two legends: the Klicky Probe by JosAr and the Euclid Probe
This design attempts to replicate Klicky as closely as possible using a PCB-based design, to try and achieve the following aims:
1. Reduce the problem of magnets working lose or seating poorly in printed parts 2. Increase the current being switched, which might possibly result in a longer switch lifetime. 3. Add LEDs.
