Connector And Signal Description
| 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 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 |
