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.

this is an updated vwesion with the 5V and GND breakouts swapped to be in keeping with the order on the BLTouch cable set. 

PLEASE MAKE SURE YOU KNOW WHICH WAY ROUND THE 5V AND GND LINES ARE ON YOUR BLTOUCH and check it matches the pinout on the silkscreen. (See also the other listing with the 5V and GND reversed: https://www.pcbway.com/project/shareproject/W234400ASJ4_Gerber_NEW_PCB_minimal_20181025122144.html)

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!
