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 SparkFun GPS-RTK2 Board - ZED-F9P (Qwiic) is a high-precision GNSS board made for projects that need far better accuracy than standard GPS. It uses the u-blox ZED-F9P module and can reach up to 10mm 3D RTK accuracy when used with proper correction data and setup.
This board is a strong choice for robotics, mapping, surveying, drones, farm systems, outdoor tracking, and other location-based projects. It can work as a rover that receives correction data or as a base station that sends RTCM 3.x correction data using survey-in mode.
Connection is beginner-friendly thanks to the Qwiic connector, so you can connect it through I2C without soldering. It also includes breadboard-friendly pins, a compact U.FL antenna connector, USB-C, UART, SPI, and I2C options for flexible setups.
The GPS-RTK2 supports multiple GNSS systems, including GPS, GLONASS, Galileo, and BeiDou, and receives both L1C/A and L2C bands. It can be powered by 5V or 3.3V, while its logic level remains 3.3V.
