10Pcs Mpr121 Breakout V12 Proximity Capacitive Touch Sensor Controller Keyboard Development Board
Description : This is a breakout board for Freescales MPR121QR2. The MPR121 is a capacitive touch sensor controller driven by an I2C interface. The chip can control up to twelve individual electrodes, as well as a simulated thirteenth electrode. The MPR121 also features eight LED driving pins. When these pins are not configured as electrodes, they may be used to drive LEDs. There a four jumpers on the bottom of the board, all of which are set (closed) by default. An address jumper ties the ADD pin to ground, meaning the default I2C address of the chip will be 0x5A. If you need to change the address of the chip (by shorting ADD to a different pin, make sure) you open the jumper first. Jumpers also connect SDA, SCL and the interrupt pin to 10K pull-up resistors. If you dont require the pull-up resistors you can open the jumpers by cutting the trace connecting them. There is no regulation on the board, so the voltage supplied should be between 2.5 to 3.6VDC. The VREG pin 2.5 and is connec Lees meer over de 10Pcs Mpr121 Breakout V12 Proximity Capacitive Touch Sensor Controller Keyboard Development Board van huismerk in de productgroep aanbieding
