Introduction

The TTP229 is a chip used for touch pads. Typically the TTP229 is used with 8 or 16 keys. Power requirements are 2.4V - 5.5V which makes them ideal to use with ESP Easy, the communication protocol is I2C so essentially only 4 cables are needed for up to 16 keys.

Hardware

1st-GPIO -> SCL on the module 
2nd-GPIO -> SDA on the module (sometimes labeled SD0)
2.4-5.5V to module VCC
