Fingerprint Reader Sensor Module 16340 Supports secondary developmentModule via a serial communication interface, directly with 3. 3V or 5V power microcontroller communication: Module data transmission feet (2 Foot TD) connected to the data bit machine receiving end (RXD), data receiver module feet (3 feet RD) connected to the data sender bit machine (TXD). For the RS 232 level (for example: PC machine) for PC communication, increase the level conversion between the module and the host computer Circuitry (e. g.: MAX232
