Introduction

ANNA-B402 is a small, stand-alone Bluetooth 5.1 Low Energy (LE) wireless module packed into a System-in-Package (SiP) design that is particularly suited for harsh professional environments. Based on the Nordic Semiconductor nRF52833 chip that includes an integrated RF core and powerful Arm Cortex - M4 with FPU processor, ANNA-B402 operates in all Bluetooth 5.1 modes – as well as 802.15.4 (Thread and Zigbee) and Nordic proprietary modes. Featuring Angle of Arrival (AoA) and Angle of Departure (AoD) transceivers, ANNA-B402 supports the Bluetooth 5.1 Direction Finding service. The service can be used for indoor positioning, wayfinding, and asset tracking. ANNA-B402 modules need only a single supply voltage in the range of 1.7 to 3.6 V and, as the supply voltage level can also be used as the I/O reference level, can be easily integrated into simple, single voltage rail systems. The broad supply voltage range makes ANNA-B402 particularly useful in battery powered systems. An additional 5 V supply is required if the USB interface is used. With the same physical size and mechanical design of ANNA-B1 module, ANNA-B402 offers a natural upgrade path for existing ANNA-B1 applications. Four additional pins on the ANNA-B402, included to increase the number of supported GPIOs module, can be conveniently accommodated within a common module footprint. The upper limit of the operating temperature range for ANNA-B402 modules is extended beyond that specified for ANNA-B1 from 85 °C to 105 °C.
