The mTouch Capacitive Evaluation Kit provides a simple platform for developing a variety of capacitive touch sense applications. Two motherboards are included in the kit, which connect to the 4 sensor boards.

This Capacitive Evaluation Kit is intended to be used to develop sensors and software using Microchip's mTouch technologies. It is used by first connecting a sensor board, and then supplying power to the board via USB, Pickit™ 2, or Pickit Serial Analyzer. The connector on the right side, with numbers 0 to 15, is the connector for sensing channels. The number, from 0 to 15, represents the microcontroller’' sensing channel. The vertical 2-row header is for debugging, to give easy access to some of the microcontroller pins. Debugging may also be done by Microchip Programmers, or by I2C™ or USB with the mTouch Diagnostic Tool.

When using the evaluation kit out of the box, the LEDs default function is to illuminate on a key press. All functionalities may be reprogrammed by using a Microchip programmer and reprogramming the firmware in the device. The firmware supplied with the evaluation kit has been written to use the four sensor boards supplied.

The USB connection supplies power to the board; No additional external power supply is needed. For independent operation, the evaluation board may be disconnected from the PC and powered at test points for independent functionality. For the PIC24F board,the USB also provides communications. The PIC16F board uses the PICkit Serial Analyzer to communicate via I2C to the PC. The PC side application that accompanies the evaluation kit allows users to monitor the performance of the touch sensors and calibrate their response. A separate, 6-wire programming interface allows users to replace the preprogrammed demo firmware with their own applications using Microchip's MPLAB Integrated Development Environment and In-Circuit Serial Programming™ (ICSP™). This allows the board to also be used as a test bed for capacitive touch sense solutions.
