Title: Acer switch keyboard hack
Post by: Kirks3dprinting on Thu, 23 April 2020, 14:51:34: Just thought I would post this hack I figured out.
I happened to come across a large supply of Acer switch detachable keyboards. SW312-31 N17H1. It's a nice action small keyboard and I wanted to use it on a kitchen computer setup because its so small. However it has no USB connector just 6 gold pins with no markings. like this:

pins
1 2 3 4 5 6
[-------------------------------------------------]
| Q W E R T Y U I O P |

|____________|SPACE BAR|_____________|

|TOUCH PAD |

Pin# 1 Ground Black wire of USB
# 2 Nothing (not used) (no connection)
#3 White wire of USB , Data -
#4 Green wire of USB , Data +
#5 Red wire of USB +5V
#6 No connection (not used)

Does anybody have an idea this might happen? should I connect the unused pins to ground? and by ground I mean either the Black ground or the shielding of the usb cable. Any suggestions?
