I am probbably blind, but I can´t find a answer.
I want install a original BLTouch v3.1 on my older CR-10s5 printer, with a board Creality v2.1 (12V).
I have Creality BLTouch kit with pin 27 board. I know how install it on ender 3 and Ender 5 boards, but here I am a little bit confused. Where I must connect pin 27 board? For display are two connectors/cables here (EXP1 and EXP2).
Which printer I need select in TH3D (TH3D_UFW_U1.R2.21a) with this board? Version for Arduino Mega 2560?
Thanks a sorry for probably stupid question.
