Seeed Studio Wio-WM1110 Development Kit

Seeed Studio Wio-WM1110 Development Kit is an all-in-one solution for developing low-power, long-range IoT positioning applications. Based on the Wio-WM1110 Wireless Module, the kit integrates a Semtech LoRa® transceiver for long-range wireless communication and low-power, high-sensitivity network coverage. GNSS and Wi-Fi® scanning offer all-around location coverage. BLUETOOTH® Low Energy, BLUETOOTH mesh, NFC, Thread, and Zigbee® are also supported.

Features

Low-power high-sensitivity LoRa/(G)FSK half-duplex RF transceiver with support in the 863MHz to 928MHz range
Multi-purpose radio front-end for geolocation with GNSS (GPS/ BeiDou), Wi-Fi, and BLUETOOTH
Rich GPIOs and compatible with over 400x Grove components for flexible expansion options

Open source platform leverages the extensive LR1110 and nRF52840 open-source ecosystem for infinite application possibilities
Built-in sensors and multiple power supply modes - temperature/humidity sensor and 3-axis accelerometer, supports both solar and battery power

Applications

Smart agriculture
Wireless meter reading
Smart cities

Asset tracking
Inventory management
Asset loss/theft prevention
