Product Overview

The N526BP is a professional, integrated USB development dongle designed for the Sub-1GHz narrowband wireless market. It centers on Texas Instruments' high-performance CC1125 transceiver, enhanced with an onboard MCU and a high-stability TCXO (Temperature Compensated Crystal Oscillator). This all-in-one device provides a complete, ready-to-use RF-to-USB solution, perfect for developing and testing applications in the 169 MHz, 433 MHz, and 868 MHz ISM bands. With excellent sensitivity (-121 dBm) and reliable +15 dBm output power, it supports robust, long-range links ideal for Sigfox prototyping, wireless meter reading, and general IoT telemetry. Its plug-and-play USB interface and accessible design make it an indispensable tool for engineers and developers.

Key Features & Benefits

• Sigfox & Narrowband Development Ready: Optimized for the Sigfox LPWAN ecosystem and other narrowband standards, providing an immediate hardware platform for protocol development and testing.

• Excellent RF Performance & Stability: Combines -121 dBm receive sensitivity with a precise TCXO for outstanding frequency stability (±1 kHz), ensuring reliable communication and compliance with strict narrowband regulations.

• Complete Integrated Solution: A true "system-on-a-stick" incorporating the CC1125 RF IC, application MCU, USB-UART bridge, and power management on a robust 4-layer PCB, eliminating external hardware needs.

• Long-Range Capability: Designed for communication up to 1500 meters, making it suitable for field testing and deployments in smart metering (AMR), agricultural sensors, and industrial monitoring.

• Developer-Centric Design: All CC1125 pins are accessible for deep customization and firmware development. The USB interface enumerates as a standard Virtual COM Port (VCP) for easy integration with any host software.

• Robust and Portable: Housed in a compact 45x19x8mm enclosure, it's built for both lab use and field testing across an industrial temperature range.
