Description
Grove module based on theFreeScale MPR121system which implements 12 touch buttons. Outputs can be connected to any objects conducting electric current. It is supplied with the voltage from3 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. This is animproved versionof the previous module, in which there is a possibility of hardware I2Caddress change and 8 crocodile clips.
