1. 15-channel touch keys with high SNR and stability. Including 6 button-wheel, 5-button slide and 4 individual touch keys. 2. Provide 3mm acrylic cover to demonstrate the touch key operation under Wheel mode or Slide mode. 3. The chip drives 4 digits display and 6 LEDs (5 com x 8 Seg). 4. One channel 10-bit ADC converter, and use potentiometer to simulate signals. 5. One channel standard UART port. 6. Embedded PWM of the chip drives buzzer directly to produce different sounds. 7. Embedded PWM of the chip drives white light LED for light adjustment purposes. 8. Enable to connect X-ISP tool via ISP ports (VCC, ICLK, IDAT, GND) to conduct real-time Touch key signal adjustment. 9. Enable to adjust, use expansion ports or the parts on the demo board through Jump.
