Interface Details 

Pin No.

Signal Name

Signal Description

PIN 1

Touch Power 3.3V

Touch   sense function need to supply power separately. 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 5

GND

GND

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.
