The N533DS is a feature-rich, high-performance Sub-1GHz RF module that combines the capabilities of Texas Instruments' CC1311R3 wireless microcontroller with an integrated Power Amplifier (PA) and Low-Noise Amplifier (LNA). Engineered for both ease of use and maximum performance, it offers an impressive +30 dBm (1W) transmit power and high sensitivity, enabling robust communication links up to 8 kilometers. A standout feature is its built-in AT command interface, allowing rapid configuration and control via a simple UART connection. Supporting a wide array of global ISM bands (169 MHz), it is the ideal solution for developers seeking a powerful yet easy-to-integrate wireless platform for demanding IoT and industrial applications.
High Power with Integrated Front-End: The +30 dBm PA and LNA provide a superior link budget for long-range (up to 8 km) and reliable communication in challenging environments.
Rapid Development & Integration: The built-in AT command set over UART allows for quick prototyping and integration without deep firmware development, significantly reducing time-to-market.
Global Multi-Band Operation: Ready for worldwide deployment with support for 169 MHz (utility) ISM bands.
Optimized for Performance & Reliability: Features a 4-layer PCB design for excellent RF performance, impedance matching, and noise immunity over an industrial temperature range (-30°C to +75°C).
Complete Developer Access: While AT commands simplify initial use, all CC1311R3 I/O pins are accessible for full custom firmware development and hardware integration when needed.
Power Efficient: Maintains excellent receiver sensitivity with a low 6.9 mA RX current and a deep 1 µA sleep current, suitable for battery-operated applications.

The module comes pre-loaded with firmware supporting a comprehensive AT command set for effortless control:
Basic Configuration: Set frequency (AT+FREQ), output power (AT+POW), data rate (AT+DATARATE).
Data Operation: Send data (AT+SEND), enter receive mode (AT+RECV).
System Control: Save settings (AT+SAVE), factory reset (AT+RESTORE), query version (AT+VER).
This feature allows the module to function as a configurable "wireless UART" cable, ideal for quick proof-of-concepts and systems where a host MCU is not intended for RF stack management.
AT Command-Based Systems: Rapid prototyping, educational kits, or products where a host processor configures the module via simple serial commands.
Long-Range Sensor Networks: Agricultural monitoring, environmental sensing, and industrial telemetry.
Smart Metering & Utility: Advanced Metering Infrastructure (AMI) on the 169MHz or 868MHz bands.
Building & Home Automation: High-performance control systems for lighting, security, and HVAC.
Custom Wireless Solutions: Developers can use AT commands initially and later migrate to fully custom firmware using the exposed pins and TI's SDK.
Quick Start Path: Use the AT command interface for immediate functionality.
Full Customization Path: Access all pins (including JTAG on DIO11/DIO12) for programming with TI's Code Composer Studio and developing proprietary or standards-based applications.
Best of Both Worlds: Offers the simplicity of AT commands for quick integration and the full power of the CC1311R3 platform for custom development.
Optimized Power Efficiency: Achieves high output power with a relatively lower peak current (700mA vs. 1A in some competitors), easing power supply design.
Reduced Development Risk: The pre-loaded AT command firmware and integrated RF front-end eliminate initial RF software and hardware hurdles.
Future-Proof: The accessible architecture allows the module to evolve with your product, from a simple AT-controlled device to a sophisticated network node.
