new revison available

If the cable that comes with your BLTouch has a fixed 1x3 wire block for attaching to the breakout pins, then you need to swap the 5V and GND around.

see this video: https://youtu.be/ocAeZRPVusw?t=341

otherwise if you have seperate du-pont style connectors then attach (or solder directly) the wires making sure 5V and GND goes to the correct marked Pins.

I have made a new revision of this board at https://www.pcbway.com/project/shareproject/BLTouch_ender3_minimal.html where the 5V and GND pins are swapped so you don't have to mod the cable or use individual dupont extenders .

Description

A minimal breakout Pin 27 for the Ender 3 3D printer to use the BLTouch auto leveler with just a stacking long pin female 2x5 2.54mm header block and a strip of 3 2.54mm header pins.

Components

Use a long pin 2x5 2.54" stackable female header block and a 1x3 strip of header pins (or right angle pins) to breakout Pin 27 for the Ender 3 3D printer to use the BLTouch auto leveler.

the stacking header pins insert through from the bottom (no silkscreen labels) so that the LCD plug attaches on the label side. it's a passthrough so you connect it exactly as if the board wasn't there at all

NOTE!

Use caution with this board as none of the parts are keyed!
