Adafruit RFM96W LoRa Radio Transceiver Breakout - 433 MHz

Sending data over long distances is like magic, and now you can harness that power with this range of powerful and easy-to-use radio modules. Transmit data miles away without the complexity of traditional connections, avoiding the limitations of WiFi and Bluetooth.Most WiFi and Bluetooth chipsets operate on 2.4GHz, perfect for high-speed transfers. For longer distances, using a lower license-free frequency like 433 or 900 MHz is ideal. Although data transmission may be slower, it covers a significantly greater area, and the technology is relatively simple; no pairing or scanning is required.Designed for use with microcontrollers, these modules simplify the creation of networks like sensor nodes or data transmissions over vast areas. They perform packetization, error correction, and auto-retransmission effortlessly. Unlike WiFi or Bluetooth, these require two or more radios with matching frequencies for effective communication.This LoRa radio module 433 MHz variant boasts a robust communication range of approximately 2Km, extendable to 20Km with optimal antennas and settings. Leveraging the SX1276 LoRa technology with a SPI interface, it offers +5 to +20 dBm power output with software-selectable settings, ensuring flexible operation. A peak transmission draw of ~100mA ensures efficient power usage, enhancing battery life for remote deployments.These modules operate in the amateur or license-free ISM band and come equipped with a 3.3V voltage regulator and level shifter for seamless 3V to 5V device integration. Some assembly is required; solder the header and create an antenna using a simple wire or choose an SMA connector for a professional setup.Sold individually, these radios are suited to talk to identical part numbers only. Thorough tutorials are provided for set-up, including wiring diagrams and example codes, facilitating seamless integration into your projects.
