TFMini - Micro LiDAR Module (Qwiic) Hookup Guide
The TFMini is a ToF (Time of Flight) LiDAR sensor capable of measuring the distance to an object as close as 30 cm and as far as 12 meters! The TFMini allows you to easily integrate LiDAR into applications traditionally reserved for smaller sensors such as the SHARP GP-series infrared rangefinders. With the added Qwiic feature, you can quickly connect to the sensor via I2C!
SparkFun GPS-RTK Dead Reckoning ZED-F9K Hookup Guide
The u-blox ZED-F9K is a powerful GPS-RTK unit that uses a fusion of IMU, wheel ticks, a vehicle dynamics model, correction data, and GNSS measurements to provide highly accurate and continuous position for navigation in the difficult conditions. We will quickly get you set up using the Qwiic ecosystem through Arduino so that you can start reading the output!
