Optotap is the Voron Tap PCB used in the Voron TAP probing assembly used by Voron 2 and Voron Trident 3D printers with the Stealthburner toolhead.

This PCB is the latest version 2.4 – changelog:

• added polyfuse to limit overcurrent and damp inrush current-induced voltage spike on hot-plugging
• added reverse polarity protection diode
• increased size of inductor to prevent coil saturation
• added a second output filter capacitor to reduce output voltage ripple
• hybrid footprint to permit use of EE-SX398 sensor in addition to Optek versions
• two-color LED to indicate status and assist with troubleshooting.
• ‘Dark Mode’ solder jumper to allow turning off indicator LEDs
• added 5V/24V selection solder jumper on rear of board to allow for easy bypassing of voltage regulator circuit
• increased thermal relief on solder pads to make through-holes easier to solder
