Read More…The TFGPSLITE02 is a compact and lightweight open-source hardware GNSS module based on the u-blox SAM-M8Q receiver. Designed for small UAVs and simple navigation applications, it offers precise positioning with support for GPS, Galileo, and GLONASS constellations.
One of its key advantages is the integrated ground plane—a conductive surface beneath the antenna that improves signal quality and reduces interference. This feature ensures more stable and accurate positioning, especially in UAV applications where signal integrity is critical.
With seamless integration via the Pixhawk Basic GPS Port, this module is an excellent choice for developers and hobbyists looking for a simple yet effective GNSS solution.
The TFGPSLITE02 is open-source hardware, allowing engineers, developers, and UAV enthusiasts to modify, improve, and adapt the design to their specific needs. Design files, schematics, and firmware resources are publicly available in the project’s repository.
The TFGPSLITE02 connects to flight controllers via the Pixhawk Basic GPS Port, ensuring hassle-free setup. The pinout is:
Pin | Signal | Voltage |
---|---|---|
1 | VCC | 5V |
2 | TX (OUT) | 3.3V |
3 | RX (IN) | 3.3V |
4 | I2C SCL | 3.3V |
5 | I2C SDA | 3.3V |
6 | GND | GND |
It also supports external payload connections for additional signals.
