## Description

#### What is it?

Pico Touch 2 - Raspberry Pi Pico Capacitive Touch Helper w/ SMD resistors assembled.

#### Why did you make it?

Helps with Raspberry Pi Pico capacitive sensing by taking care of 1M ohm resistors for you on pins 0 through 22. So 23 touch sensing inputs without the need for you to add resistors.

#### What makes it special?

AFAIK nothing else exists quite like this for the Raspberry Pi Pico. Makes capacitive touch easy. Also adds limited labels (at least some of which are unfortunately cut off) on top and duplicates most of the non-resistor pins.

Simply solder Pico or Pico W (not yet tested) to PCB, and you have a bunch of capacitive inputs ready for you to use. You can also use female headers to mount your Pico, allowing it to be easily swapped out as needed.

Current version shown in images, embedded video is an older version. Note that Raspberry Pi Pico and headers are not included. A demo of [this version is seen here](https://www.youtube.com/shorts/fh-4_6E3ol4), using cod featured in video [available here](https://github.com/JeremySCook/circuitpython-experiments/tree/main/capacitive-touch/pico-touch-2). So far that is the only testing I've done, but plan on more soon. Prototype version seen in the MIDI finger piano video below.

#### What about the Pico Touch 1?

As for the Pico Touch (original), check out [Todd Kurt's ruler-like MIDI pad design here](https://www.tindie.com/products/todbot/picotouch-capsense-midi-keyboard-for-raspi-pico/). It's a very cool device, though it's more of an all-in-one setup.

By coincidence (or subconscious memory) I came up with this name without thinking of Todd's design. The "2" was originally a reference to my [EZ Fan 2](https://www.tindie.com/products/jeremycook/ez-fan2-tiny-raspberry-pi-fan-controller/) and [JC Pro Macro 2](https://www.tindie.com/products/jeremycook/jc-pro-macro-2-rotarygpio-macro-keyboard-kit/) devices, but that ended up being quite fortuitous.

So I guess the lesson here is to add a number to the end of everything? Probably not...
