ISP1907-LL RF module offers Bluetooth 5.1 for LoRa IoT connectivity
Classic IoT applications which require Bluetooth 5.1 communication for long range and direction finding connectivity, the ISP1907-LL RF module has been introduced by Insight SiP.
It has a built-in antenna, yet is still compact, measuring 8.0 x 8.0 x 1.0mm. The ISP1907-LL RF module is claimed to provide best-in-class battery life, with power consumption around 20 to 50 per cent lower than previous generations of technology. The Bluetooth Low Energy (BLE) module is for use in most IoT applications with connected sensors for medical, healthcare, sport, fitness and industrial devices as well as home automation and beacons, adds Insight SiP. The ISP1907-LL’s long range (LoRa) capabilities enable wireless connectivity over an open field range of up to 400 metres between modules.
The RF module on the ISP1907-LL is based on Nordic Semiconductor’s nRF52811, a 2.4GHz wireless system on a chip (SoC) integrating a 2.4GHz transceiver, a 32-bit Arm Cortex-M4, with 192kbyte flash memory, and 24kbyte SRAM and analogue and digital peripherals.
The ISP1907-LL supports multiple protocols including BLE, ANT/ANT+, Thread, Zigbee and a range of proprietary 2.4 GHz protocols including Gazell from Nordic Semiconductor. It also supports a range of stacks which can be downloaded free of charge. These stacks include fully-qualified BLE stacks for the nRF52 SoC which operate with S112/S132 SoftDevices.
The ISP1907-LL is a BLE device with embedded 32MHz radio and 32kHz synchro crystals, a fully integrated RF matching and antenna and DC/DC converter including inductor, for maximum power saving efficiency. A full set of interfaces is supplied with the device for analogue or digital peripherals including 13 general purpose input/output (GPIOs) including three analogue to digital converters (ADCs) and serial peripheral interface (SPI), PDM I2C and UART buses. It offers pin-compatibility with the company’s ISP15, 18 and 19 series.
Michel Beghin, CEO of Insight SiP explained that the ISP1907-LL is suitable for customers looking for a miniature RF module to support straight-forward applications that need Bluetooth 5.1 for LoRa and direction-finding connectivity over long distances. He added that the company expects to extend the ISP1907 RF module range to support complex applications which require greater performance and memory.
The ISP1907-LL RF module is designed to run on a coin cell battery. Its low power consumption and power management system ensure the battery can last up to several years
Module prototypes are available now. Mass production will start in Q4 2019. Certification is pending.
To support product developers, Insight SiP offers a complete development kit together with sample software.
