N537AP Sub-1GHz USB RF Adapter
A Complete USB Gateway for Long‑Range IoT Development
Product Overview
If you're developing wireless sensors and need a quick way to test range, debug protocols, or set up a small network, building custom RF hardware from scratch takes weeks.
The N537AP solves that. It's a complete USB stick that turns any PC into a long‑range Sub‑1GHz radio. Inside, we paired Texas Instruments' CC1310 wireless MCU with a CC1190 front‑end (PA + LNA). That gives you +27 dBm transmit power and ‑112 dBm receive sensitivity—enough range to reach sensors 5 km away in open terrain.
All the hard RF work is done: the 4‑layer PCB is impedance‑matched, the TCXO keeps frequency stable, and the USB‑UART bridge handles communication. You just write your application code, plug it in, and start testing.
Choose the 868 MHz version for Europe, 915 MHz for the Americas bands.
Key Advantages
Plug‑and‑Play Simplicity
The stick includes everything: antenna connector, USB interface, power management, and all RF components. Connect it to a PC and you're ready to develop or deploy as a small gateway—no external hardware needed.
RF Performance That Works at Distance
The CC1310 + CC1190 combination delivers +27 dBm (500 mW) output while maintaining -112 dBm sensitivity. That's enough for reliable links across warehouses, campuses, or farms.
Professional RF Design
Built on a 4‑layer PCB with controlled impedance and good isolation. The crystal ensures frequency stability across temperature, so you don't get drift in the field.
Full Developer Access
All CC1310 debug pins are broken out. You can develop, flash, and debug directly from your IDE—no black boxes.
Multi‑Band Coverage
Separate variants for 868 MHz (EU) and 915 MHz (US/Americas). Choose the one that matches your region and application.
