N532BS-B: CC1312R + Skyworks FEM 868/915MHz Low Cost Wireless Module – 31dBm, AT Commands

📦 Product Overview

The N532BS-B is a compact, high‑performance 868/915MHz wireless module integrating Texas Instruments’ CC1312R wireless MCU with a Skyworks Front‑End Module (FEM). Designed for cost‑sensitive, long‑range applications, it delivers +27 dBm at 3V, +30 dBm at 4.2V and +31 dBm at 4.8V output power with high energy efficiency (PA efficiency > 52%), and an excellent -124 dBm sensitivity, achieving up to 8 km line‑of‑sight communication @ 50 kbps. The module supports 868/915 MHz ISM bands and is available in an SMD package for automated assembly. With all pins brought out and AT command support, the N532BS‑B drastically reduces RF design effort and accelerates time‑to‑market. Crystal options: choose between cost‑effective crystal oscillator (default) or TCXO for enhanced frequency stability over temperature.
