Seeed Studio Wio Tracker 1110 Dev Kit supports Meshtastic for off-grid communication

The Seeed Studio Wio Tracker 1110 is a dev kit designed to work with the Meshtastic network. The board is built around a Nordic nRF52840 multiprotocol Bluetooth 5.4 SoC and uses the Semtech LR1110 LoRa transceiver for communication. Seeed Studio is selling the Wio Tracker 1110 development board in a bundle with an OLED display and a GNSS receiver, providing everything needed to start experimentation for peer-to-peer LoRa mesh networking.

Meshtastic is a free, open-source, decentralized mesh network that uses LoRa radios to establish a low-power, long-range, off-grid communication system in areas without reliable infrastructure. Driven entirely by the community, Meshtastic enables decentralized, encrypted communication without the need for a dedicated router or phone.

Previously we have written various versions of the Wio Tracker including the Wio GPS and Wio LTE GPS Tracker. Since Meshtastic projects are becoming popular among developers and enthusiasts, we will likely see many more dev kits with Meshtastic support.

The board is completely open-sourced so the company provides all necessary documentation including the datasheet, Eagle CAD file, and datasheet for the modules on Seeed Studio’s products page. The Meshtastic firmware on the other hand is available on the company’s GitHub repository. For those of you who already own a Wio Tracker 1110, you’ll need the Air530 GPS receiver and the OLED, and follow the instructions to update the firmware.

The company also provides design files for an acrylic enclosure and a 3D-printed enclosure which Seeed Studio mentions will be available for purchase once the company gets enough feedback from the users.

The Wio Tracker 1110 Dev Kit for Meshtastic is available on SeeedStudio for $39.90, and you’ll also find the Wio Tracker 1110 board only on Aliexpress for $35.73.
