The BM-52833 system on chip (SoC) Bluetooth 5.1 module is based on Nordic nRF52833. The ultra-low power nRF52833 is a multiprotocol SoC with a Bluetooth 5.1 Direction Finding capable radio. It supports Bluetooth 5.1, Bluetooth mesh, 802.15.4, Thread, Zigbee, and proprietary 2.4 GHz protocols.

The BM-52833 is built around a 64 MHz Arm Cortex-M4 with FPU, and has 512 KB flash and 128 KB RAM memory available for higher value applications. it is an ideal device for a wide range of commercial and industrial applications, including professional lighting and asset tracking. A 1:4 RAM to Flash ratio and +8 dBm output power make the BM-52833 suitable for advanced earables or smart home applications where robust coverage is important.

It includes a range of analog and digital interfaces such as ADC, Full-speed 12 Mbps USB 2.0, High-speed 32 MHz SPI, UART/SPI/TWI, PWM, I2S and PDM, and has a 1.7 V to 5.5 V supply voltage range.
