Hailege 2pcs MPR121-Breakout-V12 Proximity Keyboard Touch Sensor Capacitive Touch Sensor
Hailege 2pcs MPR121-Breakout-V12 Proximity Keyboard Touch Sensor Capacitive Touch Sensor
Description: The MPR121 is a capacitive touch sensor controller controlled via an I2C interface. The chip can control up to twelve individual electrodes as well as a simulated thirteenth electrode. The MPR121 also has eight LED driver pins. If these pins are not configured as electrodes, they can be used to drive LEDs. There are four jumpers at the bottom of the board, all of which are set (closed) by default. An address jumper binds the ADD pin to ground, which means the default I2C address of the chip is 0x5A. If you need to change the address of the chip (by short-circuiting ADD to another pin), make sure to open the jumper first. Jumpers also connect SDA, SCL and the interrupt pin with 10k pull-up resistors. If you do not need the pull-up resistors, you can open the jumpers by cutting the conductor track that connects them. There is no regulation on the board, so the input voltage should be between 2.5 and 3.6 VDC. The VREG pin is connected to ground via a 0.1uF capacitor, which means you cannot operate the MPR121 in low supply voltage mode (1.71-2.75VDC) unless you modify the board. Features: 3? A current in stop mode. 12 inputs with capacitance measurement 8 inputs are multifunctional for LED driver and GPIO. Full touch detection. Automatic configuration for each sensor input. Automatic calibration for each sensor input. Touch/release threshold and debounce for touch detection. I2C interface, with interrupt output. MPR121: 3mm x 3mm x 0.65mm Operating temperature range from -40°C to +85°C. Box contents: 2 x MPR121 breakout V12 proximity keyboard touch sensor
