Product Description
The MikroElektronika MIKROE-2474 TouchKey 2 MikroBus Click Board is an accessory hardware module engineered to add advanced capacitive touch interface capabilities to microcontroller-based platforms. This board leverages ATtiny817, a Microchip AVR 8-bit MCU, utilizing its integrated QTouch controller for highly responsive touch sensing.
Featuring four separate capacitive touchpads, TouchKey 2 Click Board enables intuitive user interaction and can demonstrate both direct and projected capacitive touch technologies. The board also contains four LED indicators that illuminate when a touchpad detects input, providing real-time feedback for users.
Designed for demonstrative and embedded HMI (Human-Machine Interface) applications, the board is supplied with a plastic overlay for projected touch scenarios. This configuration allows the detection of touch through non-isolating materials, making it useful for applications where moisture protection is needed, as the overlay can shield circuitry from environmental exposure.
TouchKey 2 Click Board fits the mikroBUS socket, facilitating straightforward integration as a plug-in module without additional hardware configuration. The device connects to host boards via UART interface, enabling flexible implementation in development kits or prototyping environments.
The ATtiny817 controller supports configurable wake-up on touch and power-save modes, offering high noise immunity and moisture resistance. Its driven shield capability further enhances robustness against environmental factors. The module operates at 3.3 V supply voltage, aligning with standard mikroBUS requirements.
Package contents for this model include one TouchKey 2 click Board and one touchpad overlay. The board arrives with header strips soldered, allowing immediate installation in compatible development boards.
