Seeed Studio Wio Tracker GPS BT3.0 GSM Arduino Compatible is an open-source IoT gateway built on the ARM Cortex-M0+ and Arduino M0 MCU, designed for faster GPS tracking solutions. This Arduino- and Grove-compatible development board lets you track almost any moving object worldwide and upload data wirelessly. With integrated Bluetooth 3.0 and GPRS (LTE planned), the Wio Tracker provides flexible communication options. Unlike separate GPS/GPRS shields, this single-board solution simplifies your IoT project workflow. The Arduino and Grove compatibility accelerates development with extensive libraries and a supportive community. The included GPS library works seamlessly with Arduino IDE and C/C++. With 6 Grove connectors, developers can integrate over 180+ sensors and actuators, making prototyping and IoT application development faster and easier. The Wio Tracker is ideal for outdoor IoT projects, connecting to GPS satellites to deliver real-time location data. GPRS connectivity ensures moderate bandwidth for instant interaction between user and device. Example applications include bicycle sharing systems, pet or livestock tracking, vehicle location monitoring, and child safety solutions. As a true IoT gateway, the Wio Tracker supports additional sensors like temperature or accelerometers via Grove modules. Developers can quickly prototype, validate concepts, and scale with Seeed Studio’s support — from engineering samples to manufacturing and distribution. Whether building a GPS-based hobby project or launching a commercial IoT product, Seeed Studio helps you succeed at every stage. Note: Always connect a 3.7V Lipo battery if USB power supply is insufficient.
