Product Description
ADAFRUIT INDUSTRIES 3073 Communication & Wireless Development Tool Breakout Board is a 433 MHz LoRa RF transceiver designed for use with other microcontrollers and Arduino platforms. It operates using the SX1276 LoRa and SX1231 technologies enabling long-range communication primarily for M2M and IoT applications.
This breakout board features a SPI interface for seamless integration and includes an embedded 3.3 V voltage regulator and level shifter that supports both 3 V and 5 V devices. It allows power output up to +20 dBm (100 mW), adjustable by software, offering an approximate line-of-sight range of 2 km with simple wire antennas. Directional antennas and tuning can extend this range up to 20 km.
The radio module simplifies wireless communication by eliminating the need for association, pairing, or scanning. Data is transmitted as packets with error correction and auto-retransmission capabilities, making it suitable for sensor networks and similar applications. Transmit current peaks at approximately 100 mA at +20 dBm and consumes around 30 mA during active listening.
The compact device measures 29 x 25 x 4 mm and weighs just 3.1 g, making it a low-profile and lightweight solution for communication and wireless development projects. Operates in the amateur or license-free ISM frequency bands (EU/US).
Includes headers for easy connection; soldering is required to attach them. Supports typical Arduino libraries for packet radio communication. Each module communicates only with radios of the same frequency and model number for reliable operation.
This breakout board is ideal for applications in industrial, laboratory, IoT, and agricultural remote sensing systems, where low power, long-range wireless communication is needed. It supports rapid prototyping and development with established microcontroller platforms.
