Introduction
The E220-400M22S is a compact module developed based on the LLCC68 RF chip. The module employs LoRa modulation technology, offering superior anti-interference performance and communication range compared to FSK and GFSK modulation products. It supports a wide frequency range of 410~493MHz and is primarily designed for smart home, wireless meter reading, scientific research, medical, and long-range wireless communication applications. As a pure RF transceiver module, it requires an MCU or a dedicated SPI debugging tool for operation.
Features
- Tested communication range up to 5500 meters.
- Maximum transmit power 160 mW, software multi-level adjustable.
- Supports license-free 433/470 MHz bands worldwide.
- LoRa mode data rate: 1.76 kbps to 62.5 kbps.
- FSK mode supports up to 300 kbps data rate.
- Large FIFO capacity, supports 256-byte data buffer.
- Supports spreading factors SF5 to SF11.
- Supply voltage: 1.8 V to 3.7 V.
- Industrial-grade design, rated for long-term operation from -40°C to 85°C.
- Dual RF interface options for easy secondary development integration.
Applications
- Home security alarms and remote keyless entry systems.
- Smart home and industrial sensors.
- Wireless alarm and security systems.
- Building automation solutions.
- Healthcare products.
