SB Components has announced the launch of a dedicated location tracker with onboard Global Navigation Satellite System (GNSS) receiver and a Raspberry Pi RP2040 microcontroller: the Trekko Pico GPS Logger.

"The Trekko Pico GPS Logger is the ultimate tool for anyone who wants to document their journeys, keep a record of their favorite routes, or enhance their outdoor adventures," SB Components claims of its latest creation. "With precise tracking, long-lasting battery life, and a compact design, it's the perfect companion for explorers and travelers."

The compact data-logging location tracker is built around a Quectel LC76K GNSS module, supporting the GPS, Galileo, GLONASS, BeiDou, and Michibiki constellations with 32 tracking and 72 acquisition channels, connected to a Raspberry Pi RP2040 microcontroller β€” the same dual-core chip that's found on the popular Raspberry Pi Pico development board.

A Microchip MCP73831 charge management controller handles an external battery, not included, while a button cell can keep the module's real-time clock ticking over even when the main battery is empty. There's 2MB of flash memory, a six-pin high-density connector for unused general-purpose input/output (GPIO) pins, an RGB LED, and a microSD slot for storage.

The company has listed the board for sale on Tindie at $59.99, though at the time of writing it was showing as out of stock; source code has been published to GitHub under the permissive MIT license, with hardware schematics and mechanical data available in a separate repository under the same license.
