SB Components' Trekko Pico GPS Logger Is a Compact RP2040-Powered Location Logger
With support for multiple constellations and an open source firmware, this dinky little tracker aims to accompany you on your adventures.
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 — 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.
