Introduction

Low-power Bluetooth (BLE) RF module for short-range wireless communication applications. Features low power consumption, compact form factor, long transmission range, and strong anti-interference capability. Equipped with a high-performance inverted-F antenna. The RF-BM-ND04 BLE module uses Nordic Semiconductor's nRF52832 as the core processor. The module operates in the 2.4 GHz ISM band with GFSK modulation (Gaussian Frequency Shift Keying), 40 channels with 2 MHz channel spacing, 3 fixed advertising channels, 37 adaptive frequency-hopping data channels. The physical layer can be combined with classic Bluetooth RF to form a dual-mode device, and the 2 MHz spacing provides better protection against adjacent-channel interference. Wide output power adjustment range (-20 dBm ~ +4 dBm) with -96 dBm high-gain receive sensitivity. The nRF52832 is built around a 32-bit ARM Cortex-M4F CPU with 512KB flash + 64KB RAM. It features rich analog and digital peripherals that can interact via the Programmable Peripheral Interconnect (PPI) system without CPU involvement. The flexible 33-pin (all pins exposed on ND04) GPIO mapping scheme allows I/Os (e.g., serial interfaces, PWM, and quadrature demodulator) to be mapped to any device pin based on PCB requirements, enabling full design flexibility in pin placement and functionality. This module is suitable for developing consumer electronics and mobile peripheral products based on Bluetooth 4.0/4.2/5 (BLE), providing customers with a fast BLE solution for communication between their products and smart mobile devices.
