description Nordic Semiconductor nRF52832 Overview

The nRF52832 is a legacy but still widely used SoC for Bluetooth Mesh. While it lacks the advanced features of newer chips, its extreme reliability and low cost make it suitable for simple mesh nodes where high processing power isn't required. It remains a common choice for basic smart home devices that need to be part of a larger network.

help Nordic Semiconductor nRF52832 FAQ

Can the Nordic nRF52832 run Bluetooth Mesh?

Yes, the nRF52832 supports Bluetooth Low Energy and can run Nordic's Bluetooth Mesh software through the nRF5 SDK or newer development paths. Its 64 MHz Arm Cortex-M4F processor and 512 KB flash variants are adequate for many lighting, sensor, and relay nodes.

Does the nRF52832 support Bluetooth 5 long range?

The chip supports selected Bluetooth 5 features, but it does not provide the LE Coded PHY used for Bluetooth 5 long-range operation. Nordic parts such as the nRF52840 are better suited when coded PHY, USB, or more memory is required.

How much RAM and flash does the nRF52832 have?

Common nRF52832 variants provide up to 512 KB of flash and 64 KB of RAM. Developers must budget that memory across the application, Bluetooth stack, mesh models, and over-the-air update requirements.

Should I choose the nRF52832 or nRF52840 for a new mesh product?

The nRF52832 remains suitable for cost-sensitive Bluetooth Mesh nodes with modest memory and peripheral requirements. The nRF52840 offers 1 MB of flash, 256 KB of RAM, USB, and additional radio capabilities, giving complex products more headroom.
