The USB/TTL Raspberry Pi GPS Tracker is a compact GPS location module built around the L80-39 chip. With 66 search channels and 22 simultaneous tracking channels, it delivers fast satellite acquisition and reliable positioning accuracy down to 2.5m.
Featuring both USB and TTL interfaces, this module connects easily to Raspberry Pi, Arduino, STM32, and other microcontrollers. It includes an onboard CP2102 USB-to-TTL serial converter, an internal patch antenna for outdoor use, and an SMA connector for attaching an external active antenna when used indoors. Communication uses the standard NMEA0183 protocol at 9600 bps.
Key Features
- Dual Interface (USB + TTL) – Connect via Micro USB or 8-pin header for maximum flexibility
- L80-39 GPS Chip – 66 search / 22 tracking channels with –165 dBm tracking sensitivity
- Fast Fix Times – Cold start under 35s (under 15s with EASY technology)
- Built-in CP2102 USB-to-Serial Converter – Plug-and-play USB connectivity
- Internal Patch Antenna + SMA Connector – Works outdoors with the onboard antenna or indoors with an external active antenna
- PPS Output – Synchronise time with satellite signals for precision timing applications
- Fix Status LED – Blinks to indicate when coordinates have been determined
- Built-in LNA – Low-noise amplifier for improved reception sensitivity
- RTC Battery Compatible – Maintain time data between power cycles
- Wide Operating Temperature – –40°C to +85°C

Jargon buster
Plain-language definitions for the technical terms used above.
- baud
- Baud is the signalling rate of a serial connection, often used as the speed setting for UART communication. Matching the baud rate matters because both connected devices must use the same setting for readable data.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- GPS
- The US satellite navigation system used by GNSS receivers to calculate position and time. Support for GPS is important because it is widely available and often used together with other constellations for more reliable positioning.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- RTC
- A Real-Time Clock keeps track of time even when the main processor is asleep or powered down, usually with a small backup battery. It matters for data logging and tracking projects that need accurate timestamps.
- SMA
- SMA is a small threaded coaxial (RF) connector widely used to attach antennas and other radio-frequency cables. A device with SMA antenna ports needs antennas or pigtails with matching SMA connectors, or a suitable adapter, to connect to them.
- STM32
- STM32 is a family of microcontroller chips commonly used in embedded electronics. Knowing a product uses an STM32 can help when looking at firmware updates, pin connections, or low-level serial control options.
- TTL serial
- A simple serial data connection that uses microcontroller logic-level voltages (typically 3.3 V or 5 V) rather than the higher, inverted voltages of computer RS-232. When a device lists TTL serial, it can usually wire straight to a microcontroller's UART pins or to a USB-to-TTL serial adapter, but it needs a level converter before connecting to a true RS-232 port.
