Introduction
The AO00059 LoRa Remote control RF link is a UHF transmitter in the 902-928MHz ISM band. It used for manual
control of Airobotics’ Industrial drones during VLOS (Visual Line of Sight) operation.
The AO00059 connects to any off the shelf radio control transmitter (such as the Futaba T14SG) via the remote-
control trainer port. Connection of the AO00059 to the trainer port overrides the remote control’s internal RF
transmitter circuitry and disables it.
The AO00059 receives a PPM serial data stream from the RC remote’s trainer port. The onboard FPGA samples
the analog PPM data stream and digitizes it to binary format.
The digitized data is sent over the air using Microchip’s RN2903 LoRa Chirp Spread Spectrum Module. A CML
Micro CMX901 RF Power amplifier is used to extend the reliability of the system.
The AO00059 is designed to be powered using an off the shelf external 3S LiPo battery with XT60 connector.
An external SMA connector is used to connect the antenna to the AO00059.
LoRa is a Chirp Spread Spectrum based modulation scheme developed by Semtech.
The USB port of the AO00059 is used for configuration and engineering purposes only, this shell be done only by
Airobotics authorized personal. The USB port is used for both firmware flash, RF power amplifier calibration and
ID configuration.
