RF-BM-ND04 Bluetooth Low Energy Module
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 features low power consumption, small size, robust connection
distance, and rigid reliability. It supports BLE stack v5.0 and can be
preprogrammed with a serial interface communication protocol for simple
programming. 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
and RF-BM-ND05.
