- Smart Power Usage: With a consumption of just 14mA, it integrates high-speed RF protocols such as auto-resending of lost packets and auto-generation of acknowledge signals.
- Versatile SPI Interface: Easily compatible with both microcontroller SPI ports and I/O ports, ensuring compatibility with a range of low-speed microprocessors.
- Automated Features:
- Auto-retransmission for lost packets.
- Automatic valid data packet acknowledgment.
- Fixed frequency detection without extra programming and in-built carrier detection.
- Enhanced Error Handling: Comes with built-in hardware CRC error detection, packet transmission error counter, and carrier detection suited for frequency hopping.
- Flexible Addressing: Set up to six receiving channel addresses and pick from open receive channels.
- User-friendly Integration: Standard pin Dip2.54MM spacing interfaces are ideal for embedded applications.
The SPI interface can take advantage of the microcontroller SPI port or microcontroller I/O port to simulate the internal FIFO, making it easy to use with a variety of low-speed microprocessor interfaces and low-cost microcontrollers.
