Description
Module from the Grove series based on the FreeScale MPR121 which implements 12 touch buttons (4 included). Pins can be connected to any of the objects conducting the electric current. The sensor consists of 2 parts, the main module with the MPR121 system and four detectors of the touch pinned into the module. It is powered with the voltage from 3 V to 5.5 V, it communicates with the microcontroller via the I2C bus. The kit includes a cable adapted to Seeedstudio Base Shield v2.0.
