Meet the Wio Tracker — your all-in-one gateway to smarter IoT GPS solutions. Powered by ARM Cortex-M0+ and Arduino M0, this open-source board makes it easy to track anything that moves, anywhere on Earth, and send the data wirelessly. With built-in Bluetooth 3.0 and GPRS (LTE coming soon), you get flexible communication without the hassle of multiple add-ons. Why juggle shields when one board can do it all? Designed for makers, developers, and innovators, the Wio Tracker is fully compatible with Arduino and Grove. Tap into countless libraries and a thriving community to speed up your projects. Need more functionality? Plug in up to six Grove modules from our collection of 180+ sensors and actuators — temperature, motion, orientation, you name it. Prototyping has never been this simple. Perfect for outdoor projects, the Wio Tracker locks onto GPS satellites to deliver real-time location data. GPRS ensures smooth, instant communication between you and your device. Imagine building a bike-sharing service, tracking pets or livestock, monitoring vehicles, or keeping kids safe — the possibilities are endless. And we don’t stop at prototyping. Seeed helps you transform your idea into a custom engineering sample, then scale it into a market-ready product. We even support manufacturing and sales through our global channels. From fun DIY GPS experiments to full-scale consumer products, the Wio Tracker is here to power your journey. “I like how easy it is to use with the Arduino IDE and Grove ecosystem.” – Lisa Li, Product Manager Note: Please always plug a 3.7V Lipo battery in case USB power supply is not sufficient.
