1 Device Overview
1.1 Description
RF-BM-ND04 is an RF module based on Nordic BLE SoC nRF52832QFAA with ARM
®
Cortex
®
-M4 32-bit processor. It
integrates a 32.768 kHz and a 32 MHz crystal, an LC filter, an antenna matching and a meander line inverted-F PCB
antenna. It supports BLE stack v5.0 including the high-speed 2 Mbps feature and can be preprogrammed with a serial
interface communication protocols, such as NFC, ANT and 2.4 GHz proprietary for simple programming. RF-BM-ND04
also support Bluetooth mesh which can be run concurrently with Bluetooth LE, enabling smartphones to provision,
commission, configure and control mesh nodes. The module has NFC-A Tag for use in simplified pairing and payment
solutions. It also has numerous digital peripherals and interfaces such as ADC, PDM, PWM, I
2
C and I
2
S for many
applications. It features low power consumption, small size, robust connection distance, and rigid reliability. 1.27-mm
pitch stamp stick package for easy assembling and cost-effective PCB design. RF-BM-ND04 is pin-to-pin compatible
with RF-BM-ND04C / ND04I / ND04CI / ND05 / ND05I.
