{"product_id":"sparkfun-mikroe-touchkey-2-click","title":"SparkFun MIKROE TouchKey 2 Click","description":"\u003cp\u003eTouchKey 2 Click has four capacitive pads powered by Microchip's ATtiny817 which has an integrated touch QTouch® controller. The Click is designed to run on a 3.3V power supply. The four LEDs onboard the Click indicate when the Key (Pad) is pressed. TouchKey 2 Click communicates with the target microcontroller over UART interface (SPI interface is optional).\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eHIGH MOISTURE TOLERANCE\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eYou can use TouchKey 2 Click in all kinds of conditions, without fearing something will happen to it due to moisture and water droplets falling on it.\u003c\/p\u003e \u003cp\u003eThe plastic overlay on the TouchKey 2 Click protects the board from moisture. Thanks to this feature the electronic components are safe.
