Commonly used with Arduino Uno\/Nano, ESP32, ESP8266, Raspberry Pi, and STM32. Libraries like Adafruit Fingerprint simplify integration. Operate within 3.3V-5V range; logic level shifting may be needed for 3.3V boards if using 5V supply.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect VCC to 3.3V-5V, GND to ground, TX to MCU RX, and RX to MCU TX. A voltage divider on the RX line is recommended when using 5V microcontrollers to protect the sensor's 3.3V input. The module includes an onboard LED for visual feedback during enrollment and matching.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
