RN52m is a BLE / 2.4GHz proprietary module based on Nordic Semiconductor's nRF52832 and supports Bluetooth 5, so it can be used in various application fields.
 
The RN52m module is a module with a built-in External 32768Hz Crystal and provides 16 GPIOs. When applying the module, no separate reference other than the SWD interface and power for programming is required.
 
The RN52m module is 
RN52m uses Nordic Semiconductor SDK, and the development IDE environment supports Keil MDK v5 and Segger Embedded Studio environments.
 
RN52m supports Risenet’s wireless mesh library.
 
RN52m is provided with a separate test board, so you can quickly test the operation of the RN52m module without manufacturing a separate board. The RN52m test board can be easily connected to the J-Link OB of Nordic's nRF52-DK (pca10040), allowing programming and debugging without purchasing separate J-Link equipment.
 
RN52m module has completed KC, FCC, CE wireless certification and RoHS certification.
