Introduction

ANNA-B412 is an ultra-compact, stand-alone Bluetooth 5.7 Low Energy module packed into a System-in-Package (SiP) design with pre-flashed u-connectXpress software. Based on the Nordic Semiconductor nRF52833 chip that includes an integrated 2.4 GHz transceiver with +8 dBm output power and powerful Arm Cortex-M4 with FPU processor, ANNA-B412 standalone modules support all Bluetooth 5.1 low energy modes, including long range mode. Delivered with pre-flashed u-connectXpress software, ANNA-B412 provides support for u-blox Bluetooth Low Energy Serial Port Service, GATT client and server, Bluetooth beacons, Bluetooth long range, NFC, and simultaneous peripheral and central roles. Despite the small size, ANNA-B412 offers both internal and external antenna options. With the internal chip antenna option, ANNA-B412 can ease the integration of end-product. With the ANNA-B412 external antenna option, external antennas can be connected to an ANNA-B412 module through the antenna pin of the module. Featuring Angle of Arrival (AoA) and Angle of Departure (AoD) transceivers, ANNA-B412 supports the Bluetooth 5.1 Direction Finding service. The service can be used for indoor positioning, wayfinding, asset tracking, and more. With ANNA-B412 external antenna option, the Bluetooth 5.1 Direction Finding service may also be supported using u-connectLocate software.
