Oplink 433MHz - OpenPilot OPLink CC3D - nadajnik i telemetria do CC3D
Oplink jest nadajnikiem i odbiornikiem wspieranym przez procesor w ARM32. Zaprojektowany został specjalnie do projektu OpenPilot.
The OPLink is a radio transceiver backed by an ARM32 powered digital packet processor specifically designed for the OpenPilot project, it was originally developed under the codename: PipXtreme and there are many artifacts that still reflect this. It is a two-way radio system allowing real time telemetry information for the Ground Control Station, Wireless Configuration and even radio control from your transmitter over a single communications link.
- You will need two OPLink radios to establish a connection between the vehicle and ground station. Note that the Revolution board has an OPLink built into the flight controller. The same firmware version must be running in Revo and OPLM devices (i.e. if you upgrade one board, you will need to upgrade all others that are ‘bound’ together).
- The OPLM units operate at 433Mhz. This means that there will be a frequency conflict if you operate the vehicle using a UHF 433Mhz system. In basic terms, this conflict will lead to a loss of vehicle control and / or a crash. Use transmitters in other parts of the spectrum (i.e. 2.4G, 27Mhz, 36Mhz) for vehicle control if you intend to enable the OPLink on your Revo for transmission of telemetry data. If you wish to use a 433Mhz transmitter for vehicle control, then use an OPLM which will by default, enable the transmission of telemetry.
- Check local laws and regulations regarding radio licensing, see our Radio Licensing article for more information.
- The device that is intended to undertake the most of the transmissions should be allocated as the Co-ordinator. If you wish to use the OPLM for vehicle control, then the Co-ordinator should be the OPLM device in your transmitter module at the ground station. In this case, the Revo or another OPLink will be acting as a slave receiver but will also transmit telemetry information to your ground station which is comprised of another OPLM connected to a computer that is running the OP GCS Flight Data page. Alternatively, if you wish to simply receive telemetry data at the ground station, then the Revo should be configured as the Co-ordinator. Configuration instructions are provided below and linked-to pages.

First time use with OPLM:
- When you first try to use your OPLM with the GCS, it will not be automatically picked up by the GCS. You first need to go into the ‘Firmware’ tab and click ‘Upgrade & Erase’ while the OPLink is disconnected. Then plug in OPLink when the upgrade process asks for it. Once this has been done, your OPLM board will show up at the bottom of your GCS as a connected device. The configuration page icon at the bottom of the page icon list may be hidden without scrolling down, depending on the size of your computer screen.
