TEXAS INSTRUMENTS  FDC2214PROXSEN-EVM  评估电路板, FDC2214, 接近/电容触摸传感器 新

The is a proximity and capacitive touch sensing evaluation module. The FDC2214PROXSEN-EVM demonstrates capacitive proximity and capacitive touch button sensing with the use of "s FDC221x capacitive sensing technology. The EVM is a complete hardware and firmware solution that integrates the 4-channel FDC2214, MSP430FR5969 and the TPS61029 into one design. The firmware processes the data with an adaptive algorithm to determine whether an object is in the intended sensing area. All of the processing is done on the MSP430 so the EVM is a standalone system. Dedicated coloured LEDs light up once the device detects a target in close proximity to the board or detects a touch on the buttons. The EVM is powered by one AA battery.
