Super tiny touch switch module with LED indicator

These little modules measure 14.7 x 11mm and have a TTP223-BA6 touch switch controller and LED indicator.

Just touch the back of the PCB and the output goes high or low (you can set it active high or active low) and the LED comes on.

You can set the output to be momentary (default) or toggled (bridge the solder pads marked "B"). You can also set it active high (default) or active low by bridging the "A" solder pads.

Power supply is 2 to 5.5V DC.

Maximum sensitivity is 5mm.

Datasheet for the TTP223 IC is here (this uses the BA6 six pin variant).
