Fingerprint Sensor AS608 - A Beginner's Guide
One touch can replace keys. This project uses an optical fingerprint sensor to enroll users and then grant access with a quick scan.
read tutorial →The ESP32-C3 Super Mini Development Board is a compact WiFi and Bluetooth board for IoT projects, smart devices, sensors, automation, and portable electronics. It uses the ESP32-C3 chip with a 32-bit RISC-V processor, making it a small but capable board for wireless projects.
This board is a good choice for users who need an ESP32 board in a smaller size. It supports WiFi, Bluetooth 5 LE, USB-C programming, GPIO control, PWM, ADC, UART, I2C, and SPI for many microcontroller projects.

Connect the board to your computer using a USB-C cable. Install ESP32 board support in Arduino IDE, then select the correct ESP32-C3 board and COM port before uploading code.
Use 3.3V-safe sensors and modules when connecting to GPIO pins. Do not connect 5V signals directly to ESP32-C3 GPIO pins.
It is used for compact WiFi and Bluetooth projects, IoT devices, sensors, smart controls, and small prototypes.
The flash memory welded style uses external flash soldered on the board. The built-in 4M flash style uses built-in 4MB flash memory.
Yes. Install ESP32 board support in Arduino IDE before uploading code.
Yes. ESP32-C3 supports Bluetooth 5 LE.
No. Use 3.3V logic. Do not connect 5V signals directly to the GPIO pins.
