Description
The module with the CAP1188system that implements 8 of the capacitive touch buttons. To the holes with the pitch of 2.54 mm, you can connect, using the wires, any conductive elements and create from them the keyboard. The device works with: metal tools, fruits, vegetables and water. The board has LEDs that indicate the correct activation of the button.
The pins are holes for soldering the popular goldpin connectors - 2.54 mm pitch - strap is included in the kit for self-soldering. ChipCAP1188 can communicate through the SPI or I2C bus.
