Elecbee E22-400T30S 433/470MHz LoRa UART Transceiver Module 30dBm 1W 10km Test Range IPEX SMD

Elecbee E22-400T30S 1W LoRa UART RF Transceiver Module

The Elecbee E22-400T30S is a long-range LoRa wireless serial transceiver module designed for embedded UART communication. It operates from 410.125MHz to 493.125MHz and supports compatible 433MHz and 470MHz ISM-band applications.

The module provides up to 30dBm, approximately 1W, RF output when operated from a suitable power supply. Its programmable air data rate allows system designers to balance communication distance, transmission speed and response time.

RF Chip Note: The supplied draft identifies an SX1268 chip, while different manufacturer documents contain SX1262 and SX1268 references. The exact chip has therefore been omitted from this listing until the delivered hardware revision is confirmed.

Protocol Note: The E22-400T30S uses LoRa spread-spectrum modulation. This does not automatically make it a complete LoRaWAN modem; LoRaWAN compatibility depends on the host software and network implementation.

Reference Communication Distance

The 10km reference distance was measured under the following conditions:

Environment: Open, clear and unobstructed area
Antenna Gain: 5dBi
Antenna Height: Approximately 2.5m
Air Data Rate: 2.4kbps

Actual communication distance may be reduced by buildings, terrain, interference, antenna mismatch, cable loss, installation height, supply stability, higher data-rate settings and local RF-power limits.

Electrical Specifications

Supply Voltage: 3.3–5.5V DC
Typical Supply Voltage: 5V DC
Full-Power Requirement: At least 5V for rated transmitter output
UART Communication Level: 3.3V
Typical Transmit Current: Approximately 650mA instantaneous
Typical Receive Current: Approximately 16mA
Specified Sleep Current: Approximately 2µA
Operating Temperature: -40°C to +85°C
Operating Humidity: 10–90% RH
Storage Temperature: -40°C to +125°C

Power-Supply Requirement: Use a regulated supply capable of supporting transmitter-current peaks without excessive voltage drop. Place suitable bypass and bulk capacitance close to the module according to the manufacturer\'s reference design.

Logic-Level Warning: The module power input and UART logic are separate specifications. Use 3.3V UART signals or suitable level conversion when the connected host does not provide compatible logic levels.

Dimensions and PCB Integration

Module Dimensions: Approximately 40.5 × 25mm
Module Weight: Approximately 5.7 ± 0.1g
Mounting Format: SMD with stamp-hole pads
Antenna Options: IPEX connector or RF stamp-hole output

Follow the manufacturer\'s recommended PCB footprint, grounding and RF-layout guidance. Keep the antenna feed short, maintain the intended impedance and provide adequate ground clearance where required.

Applications and Safety

The E22-400T30S is suitable for compatible wireless telemetry, remote sensors, industrial data acquisition, environmental monitoring, automation equipment, smart metering and embedded point-to-point communication.
