Product Details
SX1268 LoRa RF Front-End Design
The E22-400T30D-V2 integrates a 50Ω impedance-matched RF front-end with SAW filtering and metal shielding. TX power loss is ≤0.5 dBm; spurious emissions are suppressed to ≤-60 dBc, fully compliant with ETSI EN 300 220 and FCC Part 15.247.
AT Command & Firmware Upgrade Support
Configure all parameters — channel, address, baud rate, TX power, and transmission mode — via standard AT commands over UART. Supports in-field firmware upgrades without hardware modification, reducing maintenance overhead in deployed networks.
Industrial-Grade Thermal & EMC Reliability
Rated for continuous operation from -40 °C to +85 °C with no output derating. Metal shielding and multi-layer PCB design ensure stable 30 dBm transmission under harsh EMC environments — suitable for outdoor enclosures, industrial cabinets, and agricultural deployments.
Ideal Applications
- Industrial Automation: Remote I/O, PLC telemetry, sensor data acquisition
- Smart Agriculture: Soil moisture/pH monitoring, weather stations, irrigation control
- Utility Metering: Water, gas, and electricity AMR/AMI systems
- Smart City: Streetlight control, waste bin monitoring, environmental sensing
- Energy & PV: Solar inverter monitoring, battery management systems
- Logistics & Tracking: Asset tracking, fleet telemetry, container status
Frequently Asked Questions
Q: Is the E22-400T30D-V2 compatible with LoRaWAN gateways?
A: The E22-400T30D-V2 uses a private LoRa protocol (P2P/broadcast/relay) and is not natively LoRaWAN-compatible. For LoRaWAN 1.0.4/1.1 (TTN, Helium, AWS IoT Core), consider the EBYTE E77 series. The E22 series is optimized for long-range private networks with simple UART integration.
Q: How do I configure the module for my application?
A: Use AT commands via any UART terminal or the free EBYTE RF Setting Tool (Windows). Parameters include: operating channel (410–493 MHz), device address, baud rate (1200–115200 bps), TX power (up to 30 dBm), and transmission mode. A USB-TTL adapter is sufficient for configuration.
Q: Does this module carry CE and FCC certification?
A: Yes. The E22-400T30D-V2 holds CE (RED 2014/53/EU), FCC Part 15, IC, and RoHS certifications. Certificate files are available for download on the EBYTE official product page.
Q: What is the maximum communication range?
A: Up to 8 km in open line-of-sight conditions at 30 dBm TX power and maximum spreading factor. Real-world range in urban or obstructed environments is typically 1–3 km. Using a high-gain directional antenna can extend range further.
