Melody IC and Touch sensor

A google search for “fritzing part TTP223 Capacitive Touch Sensor Module” turns up

TTP223B module alternative design

There is a common variant of this module (sold on popular e-commerce web sites) which looks like this: [61AFRBLqzoL.AC_SL1200] I couldn’t find a part for it, so I made one (based on an existing TTP223B module which you have already). It’s attached [removed, superseded by microMerlin’s changes], with full details on my github: The wires are connected in a different order to the original part, it looks very different, and it is a lot smaller, so I thought it might be worth including. License…

There doesn’t appear to be a part for the um66 / bt66 but a to92 transistor would be a good start.

edit:

Here is a BT66 part created from a TO93 transistor
