IoT Product designs with Direction Finding and Long Range capability
The HJ-380 module comes in a small 5.5 by 6mm form factor and is powered by Nordic’s nRF52832 multiprotocol SoC, which features a powerful 64MHz, 32-bit Arm® Cortex® M4 processor, 2.4GHz radio featuring -96-dBm RX sensitivity and a total link budget of >100dBm, and generous 512kB Flash memory plus 64kB RAM. The module is a good choice for complex wireless applications. The HJ-180 module comes in an ultra compact 5 by 5.5mm form factor and is powered by Nordic’s nRF52811 SoC. The SoC is the first product in Nordic’s low power wireless range to support Bluetooth 5.1 Direction Finding, which brings precise positioning capability to the high throughput, long range, and enhanced coexistence capabilities of Bluetooth 5. The module is suitable for complex wireless applications such as those requiring direction finding and long range.
Both the HJ-380 and HJ-180 modules feature a built-in antenna, inductor, and RF matching circuits, and operate in low power DC/DC mode to minimize current consumption. The modules are designed for beacons, proximity, health and fitness, medical, and smart lock applications.
Nordic’s nRF52811 multiprotocol SoC combines a 64MHz, 32-bit Arm Cortex M4 processor, with a 2.4GHz multiprotocol radio (supporting Bluetooth 5.1 Direction Finding, Bluetooth 5, Thread, Zigbee, IEEE 802.15.4, and proprietary 2.4GHz RF protocol software) featuring 4 dBm output power with -97 dBm sensitivity (at 1 Mbps in Bluetooth 5 mode), and 192 kB Flash memory plus 24 kB RAM.
