The 7Semi RTK ESP32-S3 Module combines the ESP32-S3 with multi-band RTK GNSS positioning in a compact development board. It provides centimeter-level positioning, Wi-Fi and Bluetooth LE connectivity, and flexible interfaces for applications such as surveying, precision agriculture, robotics, mapping, and autonomous systems.
Note -: Qwiic connector is provided for ESP32-S3 , not for the LG290P Module
