Dual Glonass GPS L1 Module With Antenna for Car Navigation, ESP32 Raspberry Pi Pixhawk Aircraft Flight Controller - UART TTL USB Connector

The VFAN Dual Glonass GPS L1 Module impresses some users with its ease of connection and functionality, especially for those involved in DIY projects. Customers have found the device relatively straightforward to use after mapping out the color-coded wiring harness for the TTL connections, which, while criticized as confusing, ultimately helped several users get the module operational. Once connected to compatible systems like the ESP32, Raspberry Pi, or even directly to a PC via USB, users noted its ability to deliver accurate NMEA data, confirming visibility to their actual locations with satisfactory precision. However, the product does come with its drawbacks. The documentation is sparse, leaving many new users frustrated when attempting to troubleshoot or set up their devices with no clear guidance. Reports of a dead support website add to this frustration, leading some to express disappointment in the lack of assistance available from the manufacturer. For individuals comfortable with electronics and problem-solving, this GPS module is seen as a functional tool that adds much-needed GNSS capability to various projects. Yet, it is not ideal for those who prefer user-friendly products with extensive support; a level of coding experience and familiarity with electronics are strongly encouraged to maximize its utility. **
