BM-52832 module is based on Nordic nRF52832 Socand PA(power amplification), it can be long distance for transmitter . The nRF52832 SoC is a powerful, highly flexible ultra-low power multiprotocol SoC ideally suited forBluetooth® low energy (previously called Bluetooth Smart), ANT and 2.4GHz ultra low-power wireless applications. The nRF52832 SoC is built around a 32-bit ARM® Cortex™-M4F CPU with 512kB flash 64kB RAM. The embedded 2.4GHz transceiver supports Bluetooth low energy, ANT and proprietary 2.4 GHz protocol stack. It is on air compatible with the nRF51 Series, nRF24L and nRF24AP Series products from Nordic Semiconductor.
