Description

Ra-01 LoRa SX1278 433MHz Wireless Module (10KM Range)

The Ra-01 is a high-performance long-range wireless transceiver module developed by
Ai-Thinker, based on the Semtech SX1278 chip. Using LoRa™ spread
spectrum technology, it overcomes the limitations of traditional RF communication, offering
extraordinary interference immunity and ultra-long-distance data transmission (up to 10KM).
It is the ultimate solution for IoT projects, remote sensing, and smart agriculture.

Key Features

Extreme Long Range: Capable of transmitting data up to 10KM in open-field (Line of Sight) conditions.
LoRa™ Modulation: Provides superior anti-interference performance compared to standard FSK/GFSK.
Ultra-Low Power Consumption: Features a sleep mode current of less than 1µA, perfect for battery-powered sensors.
High Sensitivity: Industry-leading sensitivity down to -148 dBm.
Compact Form Factor: Small SMD package (17 x 16 mm) with an integrated spring antenna for easy integration.

Full Technical Specifications

Attribute	Details
Main Chipset	Semtech SX1278
Operating Frequency	433 MHz (420MHz – 450MHz range)
Communication Interface	SPI (Half-Duplex)
Operating Voltage	1.8V to 3.7V DC (3.3V Recommended)
Max Transmit Power	+20 dBm (100mW)
Dynamic Range	127dB RSSI
Packet Engine	Up to 256 bytes with CRC
Operating Temperature	-40°C to +85°C (Industrial Grade)

Common Applications

Smart Agriculture: Monitoring soil moisture or weather stations across large farms.
Industrial Control: Long-distance wireless monitoring of machinery and equipment.
Smart City: Automated meter reading (AMR) and environmental monitoring.
Remote Robotics: Reliable control links for drones or outdoor ground vehicles.

⚠️ Critical Engineering Notes:

Logic Level: This module uses 3.3V logic. Connecting it directly to a 5V Arduino board without a level shifter will damage the chip.
Antenna Safety: Never power the module without the antenna connected. Operating without a load can cause permanent damage to the transmitter.
Power Supply: Ensure your 3.3V supply can handle the peak current (approx. 120mA) during transmission.
