Wireless RF Modules and dongles for IoT | Coral RF

N621PA is a Sub-1 GHz wireless module based on the Texas Instruments CC1312R and CC1190, designed for developers building proprietary, long-range IoT networks. Delivering exceptional +27 dBm transmit power and -112 dBm receiver sensitivity. 352KB of on-chip Flash, with generous flash and RAM, it runs complex custom stacks, advanced logic, and security. Accelerate your proprietary IoT development with this proven hardware foundation.

Why Choose the N621PA?

Complete IP and Control: retain all code, keep your stack proprietary.
Ample Space for Complex Applications: 352KB Flash – triple entry‑level 128KB – for multi‑hop routing, sensor fusion, and OTA.
Optimal Balance of Performance and Flexibility: Delivers the same +27 dBm output as flagship models, with SPI/UART for low‑level control over RF, topology, and power.
