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 →Arduino Nano with an NRF24L01+ radio baked onto the same board. Saves you the wiring and the SPI header juggling when you want a Nano that talks wireless out of the box. Program it exactly like a Nano from the Arduino IDE over micro USB.
The 2.4GHz radio does the usual NRF24 tricks: multi-channel, dynamic payload, auto-ack. Good for remote controls, sensor nodes, and small mesh setups.
| MCU | ATmega328, 16MHz |
| Memory | 32KB flash (2KB bootloader), 2KB SRAM, 1KB EEPROM |
| I/O | 14 digital (6 PWM), 6 analog |
| USB | Micro USB, CH340 |
| Radio | NRF24L01+, 2.4GHz, SPI, 250Kbps/1/2Mbps |
| Power | 5V logic, 7-12V input |
Radio pins are hardwired to the ATmega's SPI, so check the board's pin map before wiring other SPI devices.
