ISP4520 series
Built-in Antennas Combo LoRa and BLE Modules
LoRaWAN and Bluetooth 5 Ready Modules with MCU and both Radio Antennas
The ISP4520 offers a unique combination of two leading IoT radio technologies in one class leading miniaturized package. With integrated BLE and LoRa connectivities, this module offers the long-range capability of LoRa for data transmission over distance, combined with the high-throughput flexible service of BLE for a more local connection that can be used to carry out configuration, commissioning and update via smartphone or tablet applications.

Module Description
This module combines two radio devices – the Nordic Semiconductor nRF52832 Bluetooth Low Energy chip, and the Semtech SX1261/2 LoRa Transceiver. The onboard ARM Cortex processor on the Nordic device acts as the controller for both radios, and is also an open device allowing customers to add their own applications. It has a rich set of peripheral connections, allowing the connection of sensors and indicators, as well as digital connections which could be used to connect to other systems.
The module integrates antennas for both Bluetooth and LoRa, making it the world’s smallest device to offer fully integrated connectivity for both protocols. It also enables full radio certification, making this module uniquely easy to use to build long range radio applications.
