Link.ONE is a multifunctional device integrating Nordic nRF52840, Semtech SX1262, and Quectel BG77, providing LoRa/LoRaWAN, Bluetooth Low Energy, and LTE CAT M1 & CAT NB2 communications. To ensure optimal connectivity, we offer a modified Unify enclosure measuring 100x75x38 mm, equipped with USB access and an external 2.1 dBi LTE antenna.

LoRaWAN is based on the V1.0.2 stack and supports all official regions. Bluetooth Low Energy complies with BLE 5.0 specifications.

The Link.ONE features an NB-IoT and LTE-M cellular module supporting CAT M1 and CAT NB2 IoT cellular protocols. Based on the modular WisBlock ecosystem, Link.ONE offers the possibility to add sensors to the device by connecting them to the device itself.

Note: If you are using a non-rechargeable battery with the WisBlock baseboard, you must disconnect it before plugging the USB cable into the board's port to configure the device. Otherwise, the battery and board may be damaged and cause fires.
