Wireless RF Modules and dongles for IoT | Coral RF

The N532BS is a next‑generation 433MHz RF module that pairs Texas Instruments’ CC1312R wireless MCU with an integrated high‑efficiency power amplifier (PA). Engineered for industrial‑grade, long‑range applications, it delivers an impressive +26 dBm output power and an outstanding -124 dBm receiver sensitivity – achieving a 139 dB link budget and reliable communication over 2 km line‑of‑sight.

Housed in a compact 30 × 21 × 3 mm SMD package, the module features a 4‑layer PCB with optimized RF layout, separate PA supply, and full I/O access (35 pins). It is the ideal building block for custom, high‑performance wireless systems in the 433 MHz ISM bands.
