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.\u003cspan\u003e \u003c\/span\u003e\u003c\/span\u003e\u003cspan class=\"a-list-item\"\u003eThere 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 the 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 do not require the pull-up resistors you can open the jumpers by cutting the trace connecting them.\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003ch4\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003e Capacitive touch sensor controller driven by an I2C interface.\u003c\/li\u003e\n\u003cli\u003eCan control up to twelve individual electrodes, as well as a simulated thirteenth electrode.\u003c\/li\u003e\n\u003cli\u003eEight LED driving pins.\u003c\/li\u003e\n\u003cli\u003eConnection to the microcontroller \/microprocessor via I2C bus.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003chr\u003e\n\u003ch4\u003e\u003cstrong\u003ePackage Includes:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003e1 x MPR121 Breakout V12 Capacitive Touch Sensor Controller Module I2C keyboard\u003c\/p\u003e\n\u003cp\u003e1 x 6pin Male Header\u003c\/p\u003e\n\u003cp\u003e1 x 12pin Male Header\u003c\/p\u003e\n\u003cp\u003eSpecification:\u003c\/p\u003e\n\u003ctable class=\"specs-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel No:\u003c\/td\u003e\n\u003ctd\u003eMPR121\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial:\u003c\/td\u003e\n\u003ctd\u003eAlloy+Plastic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterface:\u003c\/td\u003e\n\u003ctd\u003eI2C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength (mm):\u003c\/td\u003e\n\u003ctd\u003e30\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth (mm):\u003c\/td\u003e\n\u003ctd\u003e20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (g):\u003c\/td\u003e\n\u003ctd\u003e10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e0.015 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Dimensions\u003c\/td\u003e\n\u003ctd\u003e5 × 5 × 1 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Jaideep Robotics","offers":[{"title":"Default Title","offer_id":46271919849645,"sku":"1270230","price":97.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0773\/7638\/9293\/files\/download_58.avif?v=1781957226","url":"https:\/\/jaideeprobotics.com\/products\/mpr121-breakout-v12-capacitive-touch-sensor-controller-module-i2c-keyboard-normal-quality","provider":"Jaideep Robotics ","version":"1.0","type":"link"}
