OpenTX is open source project for creating software that runs your RC radio transmitters. The project develops two pieces of software: Companion and Firmware.
OpenTX Companion is used for many different tasks like loading OpenTX firmware to the Transmitter, creating & backing up models, editing Radio & Model settings and has a Radio simulator.
OpenTX Firmware is radio firmware that is highly configurable and brings a ton features than found in traditional radios.
Something also to mention is the SD Card Content that is also paired with the firmware.
