Future Technology Devices International (FTDI) is a Scottish privately traded semiconductor device company, which specialized in Universal Serial Bus (USB) technology. FTDI provides application-specific integrated circuit (ASIC) design services. The consultancy services are also provided by this firm for product design, specifically in the realm of electronic devices. The firm is headquartered in Glasgow, Scotland, United Kingdom.

A touch control input/output application boards has been introduced by FTDI, which is for the Vinco development module. The Vinco Touch Key applications board is called shield which is in the line with Vinco motherboard. This board incorporates STMPE821 8-channel general purpose input/output (GPIO) capacitive touch key controller IC. 8 touch keys of the shield use a capacitive sensing technology, responding to physical input stimulus from the user. It also has a set of 4 push buttons and 5 GPIO-controlled LED indicators.

On the Vinco module via an I2C bus, the touch keys can pass input data to the Vinculum-II (VNC2) dual port USB host/device controller IC. Moreover, access to the Vinco pulse width modulation (PWM) interface is possible on the header pins. An external supply or the Vinco motherboard connections can feed to shield for it needs a 5V supply. Vinco platform use the Android Open Accessory initiative; therefore, the devices with Android system can control items of external hardware through a human machine interface.
