Processing power Multiprotocol radio(bluetooth low energy,ANT,2.4G proprietary) Power efficiency WLCSP Hardware module : SWD programmer (SWDIO,SWCLK,,GND) nRF52832 WLCSP Size :9.4 x 9.25mm BLE stack & RF 2.4Ghz type: Bluetooth Module color:Black Material:PCB size:9.4 x 9.25 x 2MM Package Contents: 1 x Bluetooth Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm. The Bluetooth module is based on Nordic nRF52832 Soc , The nRF52832 SoC is a powerful, highly flexible ultra-low power multiprotocol SoC ideally suited for Bluetooth low energy (previously called Bluetooth Smart), ANT and 2.4GHz ultra low-power wireless applications. It is on air compatible with the nRF51 Series, nRF24L and nRF24AP Series products from Nordic Semiconductor. The nRF52832 SoC is built around a 32-bit ARM -M4F CPU with 512kB + 64kB RAM. The embedded 2.4GHz transceiver supports Bluetooth low energy, ANT and proprietary 2.4 GHz protocol stack.
