The all new Orange OpenLRSng is an open source transmitter module and receiver combo pack that can be programmed to use your choice of protocol and any channel in the 915MHz range. It is a fully user-customizable RF transmitter system that can even be programmed to utilize additional features such as telemetry, operative remote control via stics (cPPM ready) and mission control.
The module is designed for using with APM flight control software and is equipped with Bluetooth technology so the user can connect it to a tablet, smartphone or PC. All telemetry data, mission planning and flight modes will be available in APM Mission Planner on PC or Droid Planner or similar app's for Android devices. Thanks to the bluetooth function, no additional leads are required to setup / program the transmitter module.
The Orange OpenLRSng is an extremely versatile system and is perfect for custom projects,
It utilizes a 1000mW RFM22B RF unit and Atmega328 processor with Arduino Bootloader
allowing you to upload pre-written codes or write your own to suit your transmitter needs.
The default code utilizes 3 channel frequency hopping spread spectrum technology. If you would like to use a different protocol, you can write your own hopping codes or simply download one of the many pre-written OpenLRS code sets already available.
