BLE direction finding with SA Bluetooth 5.4 module

High-performance, long-range, and reliable wireless operation are crucial for IoT applications. With iVativ's NEVA module, Rutronik presents a component designed precisely for this purpose. NEVA is an ultra-low-power standalone module based on Nordic Semiconductor's nRF52833. It simultaneously supports Bluetooth 5.4, 802.15.4 Thread, and ZigBee and provides an integrated NFC-A tag. The highly efficient development environment makes the module ideal for applications in many IoT industries, such as home automation, wearables, IIoT, and smart medical.

The integrated high-performance ARM Cortex-M4 with 512kB Flash and 128kB RAM decreases system costs and provides design flexibility. With integrated wireless and network stacks, application APIs, and security features supported by ARM Trust Zone Cryptocell-310, this module lowers time-to-market and development costs.

The modules have a small footprint of 10mm x 15mm x 1.6mm, an integrated PCB antenna or MHF4 connector, and a range of over 1,400m. The component also impresses with its extremely low power consumption of 450nA in deep sleep mode, 1.5µA in system standby mode, and 4.8mA in TX at 0dBm output power.

Typical application examples include direction finding, personal fitness devices, wearables for wireless payments, connected health, applications for AR/VR, smart home sensors and controls, industrial IoT sensors and asset trackers, and localisation devices.
