Nordic nrf52832 Bluetooth 5.0 RFstar UART PCB low power consumption Long range Bluetooth 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 UART 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.
