The 7Semi RTK ESP32-S3 Module is a compact, high-performance development board that combines the processing power of the ESP32-S3 with RTK-enabled GNSS positioning. Designed for precision applications, it delivers centimeter-level accuracy by integrating an advanced GNSS module with RTK (Real-Time Kinematic) support.
This module is ideal for developers building solutions in precision agriculture, robotics, surveying, asset tracking, and autonomous systems. With onboard USB-C, flexible GPIO access, and a dedicated antenna interface, it enables reliable wireless communication alongside high-accuracy positioning in a single platform.
