Bluetooth modules enable long range feature in IoT designs
SG Wireless™ has launched its latest wireless Bluetooth® 5 and Bluetooth Low Energy (LE) modules, the SGW1010 and SGW1011.

Powered by Nordic's nRF52840 Bluetooth 5/LE advanced multiprotocol System-on-Chip (SoC), the modules are designed for use in a range of IoT applications including connected home, smart city infrastructure, industrial mesh networks, industrial smart lighting, and transport and logistics.

The SGW1010 module provides an embedded PCB antenna, while the SGW1011 module offers a u.FL connector for an external antenna. Both modules take advantage of the nRF52840's 64-MHz, 32-bit Arm® Cortex® M4 processor with floating point unit (FPU), a 2.4-GHz multiprotocol radio (supporting Bluetooth 5, ANT™, Thread, Zigbee, IEEE 802.15.4, and proprietary 2.4GHz RF protocol software) with 1-MB Flash memory and 256-kB RAM to provide an advanced, highly flexible, ultra low power multiprotocol system enabling Bluetooth LE connectivity for portable and extremely low power embedded systems.

The SGW1010 and SGW1011 modules with a form factor of 10.2- x 15- x 2.1-mm are designed to reduce the engineering efforts and development costs associated with adding Bluetooth 5 to any product, thereby accelerating its time to market. Enabled by the nRF52840 SoC's support for Bluetooth 5, the modules allow OEMs to utilize the Bluetooth 5 Long Range and advertising extension support in IoT product designs. The integrated nRF52840 SoC provides full Bluetooth 5 support, including 2x on-air raw data bandwidth (2 Mbps); 4x range; and 8x broadcasting ability with advertising extensions that increase the advertising packet payload size to 251 bytes. The nRF52840 SoC's new radio architecture with on-chip PA provides -95 dBm RX sensitivity (at 1 Mbps in Bluetooth LE mode), a maximum output power of 8 dBm, and a total link budget of 103 dBm.
