The MPR121 Breakout V12 Capacitive Touch Sensor Controller Module, driven by an I2C interface, is designed for controlling up to twelve individual electrodes and features eight LED driving pins. Additionally, there are four closed jumpers on the bottom of the board, one of which ties the ADD pin to ground. This sets the default I2C address to 0x5A, which can be changed by opening the jumper and shorting ADD to a different pin. The board does not have regulation, so the voltage supplied should be between 2.5 and 3.6VDC. Customers should note that operating the MPR121 in low-supply voltage mode (1.71-2.75VDC) requires modifying the board. The MPR121 Breakout V12 Capacitive Touch Sensor Controller Module is approximately 3x2cm in size and comes brand new with high quality.
