Description
The simpleRTK3B Heading is a standalone board designed to evaluate dual-band RTK GNSS technology, offering centimeter-level accurate positioning, sub-degree heading, microSD datalogging, and optional native Ethernet functionality. Based on the Septentrio mosaic-H module, similar to simpleRTK3B heading from Ardusimple, it can function independently or connect with various platforms such as Arduino, Ardupilot/Pixhawk (JST connector), Raspberry Pi, Nvidia Jetson, and STM32 Nucleo, providing up to 20 RTK positions and attitude (heading) updates per second. This board is ideal for advanced projects utilizing the Pixhawk autopilot.
