Signal Name

Signal Description


Touch Power

Touch   sense function need to supply power separately. Power: DC3.3V±0.1V, Current:   1.5uA to 2.5uA


Finger Detect

Output high level   when detected finger, and output low level once finger left



Module transmit   output, 3.3V TTL logic



Module receive   input, 3.3V TTL logic






DC input, range of   Voltage is 3.3V ± 10%


FP Reset

Reset at low level   (reset time>100ms), Work at high level. After Reset, it will cost about   350-400ms for system initializing and programs loading; Only after that the   module can communicate with MCU by UART.
