Voron v0 Hartk Simple Display Rev2

Designed and open-sourced by Hartk, the Voron V0 simple display uses a single ribbon cable to connect the display to the skr mini e3 v2 board. You don’t need anything else. No USB cables, no breakout boards, nothing! It’s plug and play.

Our display has the RGB Led included that can be configured to light up different colors according to different actions and status. Encoder rotates and clicks to allow navigation through the menu. Reset button on the right.

Recommend for voron v0.1 with SKR Mini. This product won’t work with SKR Pico.

This item is fully soldered and in ready condition to be used.

Includes 50cm 10pin ribbon cable.

We suggest printing these printed parts edited by us to fit this product properly instead of the original. Please super glue the spacer.stl between the bottom of the display and the PCB

Example how to change to red color:

SET_LED LED=display_led RED=1.0 GREEN=0.0 BLUE=0.0 INDEX=1 TRANSMIT=1 SYNC=1

If your display is VCC GND SCL SDA and your display is getting too hot, its becaused vin and ground is switched and you need to cut trace and solder the pads on the back of the PCB. Cut the trace in green color and solder the two other pads in red color. Make a continuity test before connecting it to the mother board.
