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 |
