ISP4520 Smart LoRa and Bluetooth Low Energy Combo Module

LoRaWAN and  Bluetooth Low Energy 5 Ready / ANT+ NFC /with MCU and Two Antennas


Features | Applications | Block Diagram | Main Specifications | Product User Guide |Dev Zone


The ISP4520 offers a unique combination of two leading IoT radio technologies in one class leading miniaturised package.
With integrated BLE and LoRa this module offers the long-range capability of LoRa for data transmission over distance, together with the high-throughput flexible service of BLE for a more local connection. This provides perfect flexibility of long range data acquisition, combined with the capacity to carry out configuration, commissioning and update capabilities via radio communications built into any smartphone or tablet.
The module measures 9.8 x 17.2 x 1.7 mm and incorporates chips from the leading semiconductor vendors for each technology – Nordic Semiconductor (for BLE) and Semtech (for LoRa). Processing power is provided by the Nordic nRF52’s onboard M4 floating point processor, with 512K of flash memory available for advanced applications. The Semtech SX1261 (for EU and JP versions) or SX1262 (for US version) provide the LoRa radio function.
Both semiconductors offer best in class low power consumption, coupled with an array of power saving features, allowing for multi-year coin-cell operation (depending on application use-case). The module integrates antennas for both LoRa and BLE transmission, thus allowing this device to be a pre-certified complete radio and application core solution, requiring only external sensors, or connection to a customers existing device. An external antenna can also be attached to provide maximum transmission range for the LoRa.The module is supplied with a combined BLE and LoRaWAN stack

Block Diagram

This highly miniaturized LGA module, 9.8 x 17.2 x 1.7 mm, is based on the new SX126x LoRa transceiver series and nRF52832 BLE chip. Using a simple user interface via the SPI connection and integrating a Cortex™ M4 CPU, flash and RAM memory combined with single optimized antenna for both LoRa and BLE standards, ISP4520 offers the perfect stand-alone module solution for large spectrum of application in IoT domains. For longer range use case, ISP4520 can be used in conjunction with an external LoRa antenna.
