The Vinco Touch-Key is a shield that mates with the FTDI Vinco development module to allow touch pad operation. The shield includes an STMPE821 device, which is an 8-channel GPIO capacitive touch-key sensor. The sensor communicates to the Vinculum-II (VNC2) (on the Vinco module) via I²C protocol.

Vinco is a development module inspired by the Arduino concept and uses the Vinculum-II (VNC2) dual port USB Host/device IC. Vinco uses a VNC2-64Q package to facilitate 38 GPIO options on 0.1" pitch sockets. Vinco is designed as a prototyping platform for VNC2 based designs and applications.
