■Interface with MCU through I²C bus.

■Fast and accurate results at very low power consumption

Description

STEVAL-IHI002V1

This demonstration board is designed to modernize or even fully replace a mechanic keyboard. The demonstration board is based on the STMPE1208S device, a 12-bit GPIO expander with an additional 12-channel capacitive sensing sensor, which is able to interface a main MCU through I²C bus. The demonstration board is designed to work as a daughter board for the STEVAL-IHI001V1 (washing machine user interface). Once plugged in, the STEVALIHI002V1 is automatically detected by the mother board, replacing the mechanic keys by a wheel, a slider and 5 buttons.
