Overview

NRF52832AA(holyiot-17095) which we selected Nordic nRF52832 WL-CSP Chip(BGA
chip) ,the NRF52832AA is very very Tiny module , the size is just about 9.4mm*9.25mm ,
just like a finger size.
The NRF52832AA is a powerful, highly flexible ultra-low power multiprotocol SoC ideally

suited for Bluetooth low energy (previously called Bluetooth Smart),32-bit ARM ® cortex
TM -M4F ,
Which support Bluetooth 4.0 ,BLuetooth mesh . there are 11 GPIOs , we also layout the
SWDIO,SWCLK ,VCC and GND for the developer debug and program by themselves.
