Microchip Qtouch Capacitive Touch Demonstration Kit for ATSAMD20-Q

QTouch SAM D20 Robustness Demo Kit

The QTouch SAM D20 Robustness Demo Kit allows designers to apply QTouch technology into their capacitive touch designs and to focus on innovation and ease of use . As a self-sufficient unit with it's own on-board microcontroller, the QTouch Demo Kit helps to achieve a high level of noise immunity and moisture tolerance - requirements that are key to any quality capacitance touch application.

The kit is comprised of two PCBs that run off the SAM D20 microcontroller and are connected to each other by way of a flex cable - the top PCB which features mutual capacitance sensors and LEDs and the bottom PCB which features self-capacitance sensors and any other electronics.

Features;
High noise tolerance levels
High moisture tolerance
Supports up to 256 channels
Low power consumption as low as 3μA
Touch response time of typically 30 ms with 10 V CI and moisture
6 self-capacitance buttons
4 mutual capacitance buttons
Individual LEDs for indicating button status
1 8-channel capacitance slider
Buzzer for audio feedback
On-board embedded debugger module
Connectivity with QTouch Analyzer
