Nordic nRF52811 Long distance and low pwer consumption chip BLE 5.1 mesh module
RF-BM-ND08A is an RF module based on Nordic BLE SoC nRF52811QFAA 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 v5.1 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-ND08A is pin-to-pin compatible with RF-BM-ND08.
