Overview

This is the 900 MHz radio version, which can be used for either 868MHz or 915MHz transmission/reception - the exact radio frequency is determined when you load the software since it can be tuned around dynamically.These are +20dBm FSK packet radios that have a lot of nice extras in them such as encryption and auto-retransmit. They can go at least 500 meters line of sight using simple wire antennas, probably up to 5Km with directional antennas and settings tweakings

These modules are great for use with Arduinos or other microcontrollers, say if you want a sensor node nework or transmit data over a campus or town. The trade off is you need two or more radios, with matching frequencies. WiFi and BT, on the other hand, are commonly included in computers and phones.

These radio modules come in four variants (two modulation types and two frequencies) The RFM69's are easiest to work with, and are well known and understood. The LoRa radios are exciting and more powerful but also more expensive.

Technical Details of Radio Breakout

  • SX1231 based module with SPI interface
  • +13 to +20 dBm up to 100 mW Power Output Capability (power output selectable in software)
  • 50mA (+13 dBm) to 150mA (+20dBm) current draw for transmissions, ~30mA during active radio listening.
  • Range of approx. 500 meters, depending on obstructions, frequency, antenna and power output
  • Create multipoint networks with individual node addresses
  • Encrypted packet engine with AES-128
  • Packet radio with ready-to-go Arduino libraries
  • Uses the license-free ISM band: "European ISM" @ 868MHz or "American ISM" @ 915MHz
  • Use a simple wire antenna or spot for uFL or SMA radio connector
  • 25.3mm x 29.3mm x 3.5mm / 1.0" x 1.15" x 0.14"
  • Weight: 3.4g
