Module connection and compatibility
The module communicates via UART interface and works at 115200 bps by default. GND, 5V, TX and RX connections are required for communication - 4-pin plug with 2 mm pitch (supplied in the kit) fits Grove type ports (PORT.C). The module works with many programming platforms, such as Arduino IDE, ESP32-IDF and UIFlow , which provides great versatility of integration with various M5Stack series microcontrollers, such as Core , Atom or StickC .
The module offers two Lego-compatible holes.
The module has an SMA connector for an external antenna included in the kit.
Practical applications
The GPS / BDS Unit module is ideal for:
- Navigation systems for autonomous vehicles
