Interface Details 

Pin No. Signal name Signal Description
PIN 1 Touch Power 3.3V Touch sense function need to supply power separately (It is
better the power can be controlled). Power: DC3.3V± 0.1V
Current:1.5uA to 2.5uA
PIN 2 Finger Detect Output high level when detected finger, and output low level
once finger left
PIN 3 UART-TX Module Transmit Output,3.3V TTL Logic
PIN 4 UART-RX Module Receive Input,3.3V TTL Logic
PIN 6 VIN DC Input, Range of Voltage is 3.3V±10%
PIN 7 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
