BM833
Overview
The BM833 is a powerful, low-power Bluetooth 5.1 and 802.15.4 module based on the Nordic nRF52833 SoC. It features an integrated PCB trace antenna and a 64MHz ARM Cortex M4F processor with 512kB Flash and 128kB RAM, making it suitable for complex mesh networking and direction-finding applications. The module's wide supply voltage range of 1.7V to 5.5V allows for direct operation from USB or various battery chemistries.
Why Choose This Part
The module includes an integrated DC-DC converter with embedded inductors to minimize external component count and power consumption. Its support for Bluetooth 5.1 Coded PHY provides significantly extended range without requiring external power amplifiers. Additionally, the inclusion of an NFC-A tag interface enables simplified Out-of-Band (OOB) pairing for a better user experience.
Applications
Key Specifications
Getting Started
Engineers can develop for the BM833 using the Nordic nRF Connect SDK and the SEGGER Embedded Studio IDE. The module is compatible with Nordic's SoftDevices and can be programmed via the SWD interface. For rapid prototyping, Fanstel provides the EV-BM833 evaluation board which breaks out the module's I/O and USB pins.
