RS485 is renowned for its robustness, reliability, and ease of use. This differential communication system enables data transmission at moderate speeds over long distances, making it ideal for noisy industrial environments.

Features:

  • Supports RS485 / EIA-485 standard.
  • Designed for industrial communication standards such as MODBUS and DMX.
  • Excellent EMC (Electromagnetic Compatibility) and EMI (Electromagnetic Interference) performance.
  • Differential signal transmission helps minimize noise and interference.
  • Supports data rates up to 35 Mbit/s (short distance) and 100 kbit/s (long distance).
  • Multi-point communication: supports up to 40 devices on a single bus.
  • Half-duplex mode operation (send or receive at one time).
  • Termination resistor option (short R0) for long-distance transmission.
  • Signal indicators for RXD and TXD.
  • Lightning protection and strong anti-jamming capability.

Features

  • LoRa SX1276 Wireless Module: Built around the SX1276 chip, the module employs LoRa technology, allowing for long-range data transmission and excellent penetration capabilities.
  • Configurable Output Power: The module's output power can be adjusted from +13 to +20 dBm (up to 100 mW) through software settings, providing flexibility in balancing communication distance and power consumption.
  • Low Power Consumption: During transmission, power consumption ranges from 50mA (+13 dBm) to 150mA (+20dBm), while in listening mode, it requires approximately 30mA, making it energy-efficient for battery-operated applications.
  • AES-128 Encryption Support: The module offers AES-128 encryption, ensuring secure and private data transmission, making it suitable for applications that require data confidentiality.
  • Multipoint Network Capabilities: It supports multipoint networks, allowing the establishment of individual nodes within the network for seamless and efficient communication.
  • Wide Power Supply Range: The module can be powered with a voltage range from 3V to 5V, making it compatible with various power sources and microcontrollers.

NOTE: It is important to solder a 16cm length of cable to the antenna pin before using it since not connecting any antenna can damage it. Optionally, the board has pads to solder an SMA connector with antenna thread.
