FAQ (Foire aux questions)
Q: Is there an ultra-wideband video receiver (VRX) that supports frequencies up to 12 GHz? Are there any plans for such a product?
UN: À l'heure actuelle, our video receivers support frequencies up to 7.5 GHz. Support for the 12 GHz band is not available in our current lineup. We are currently developing a new FPV VRX with an extended frequency range of up to 10 GHz. Expanding into higher frequency bands involves significant engineering challenges and requires thorough development and testing, so we are not able to provide a confirmed release timeline at this stage.
T1: What frequency range does this receiver support?
UN: The receiver supports an ultra-wide frequency range from 200MHz to 7.5GHz, allowing operation across multiple RF bands. The default antenna frequency range is 860-8000MHz. If you modify the operation frequency is from 200-860MHz, you have to use this range antenna.
T2: Can I customize the frequency manually?
UN: Oui. You can adjust frequencies using UART serial commands for precise control. You can set the frequency by sending a command. Par exemple:bp:5765\r\n
This command sets the FPV VRX frequency to 5765 MHz.
T3: How do I change the starting frequency via UART?
UN: Connect the receiver to a serial tool, configure the correct COM port and baud rate, enable ASCII mode, send the desired frequency command, and restart the device.
Q: What frequency range is supported?
UN: The system supports frequency input from 200 MHz en 7500 MHz. Any user define frequency, Par exemple: 980 MHz, 3765 MHz, 4988 MHz, etc..
Q: Can I set multiple custom frequencies or scan frequencies automatically?
UN: Actuellement, only one custom frequency can be set at a time. Automatic frequency scanning (full-band scan) is not available in the current version.
Q: Does the device include preset frequencies?
UN: Oui, several commonly used frequencies are preset for convenience.
UN: Oui. In addition to the two hardware buttons, the receiver also provides a UART serial interface. You can send commands through this UART port to control the FPV VRX, such as changing frequency and potentially other functions.
UN: It depends on the frequency range you switch to. The default antenna supports a very wide frequency range (environ 800 MHz en 8 GHz). If your new operating frequency falls within this range, you generally do not need to replace the antenna. Cependant, if you change to a lower frequency band such as 200–800 MHz, the default antenna may no longer perform efficiently, and replacing it with a compatible antenna designed for that range is recommended.
En plus, while wideband antennas offer convenience, you may achieve better performance by using an antenna tuned for a narrower frequency band. Narrowband antennas typically provide higher gain and improved signal quality within their specified range.
Q: Do you have any documentation describing the UART communication protocol?
UN: À l'heure actuelle, there is no formal UART communication documentation available.The UART interface currently supports a single basic command for changing the frequency: pb:5765\r\n This command sets the receiver frequency (in MHz). Aside from this frequency-setting command, no additional UART commands are supported at this time.
Q: If I send a UART command like bp:5765\r\n, will the receiver switch to 5765 MHz immediately? Do I need to reboot or confirm using buttons?
UN: Oui, the receiver will switch to the specified frequency immediately after the command is received. No reboot or manual confirmation via hardware buttons is required. The change takes effect in real time as soon as the UART command is processed.
Q: Can I send multiple UART commands in sequence with different frequencies (par ex., bp:5765\r\n, then another frequency, etc.)?
UN: Oui, you can send multiple commands in sequence. The receiver will automatically switch to the new frequency each time a valid command is received. Commands are processed one by one in the order they are sent. Cependant, the FPV VRX can only operate on one user-defined frequency at a time. While each command is executed sequentially, only the most recently set frequency is retained. Any new command will overwrite the previously configured frequency.
Q: What is the approximate switching time from sending a UART command to getting a stable video signal?
UN: After sending a UART command, the receiver typically switches to the new frequency within a few seconds. The time required for a stable video signal to appear depends on signal strength and quality. Under strong signal conditions, the video will appear quickly. In weaker signal conditions, it may take longer for the image to stabilize.
Q: Did I understand the UART settings correctly — 115200 baud, 8 bits de données, pas de parité, 1 peu d'arrêt, ASCII commands?
UN: Oui, your understanding is correct. The UART interface uses the following configuration: Débit en bauds: 115200; Data bits: 8; Parité: Aucun; Bits d'arrêt: 1; Command format: ASCII. This configuration (commonly referred to as 115200 8N1) is correct for communicating with the device.
Q: What UART voltage level is used on the board: 3.3VTTL, 5VTTL, or RS232?
UN: The board uses 3.3V TTL UART logic levels. Only a shared ground (GND) connection is required between devices for communication. Please note that the interface is not RS232 compatible, and RS232 signals must not be connected directly to the UART pins, as this may damage the device.
Q: Can you make your wideband FPV VRX support frequency control via SPI?
UN: The standard version supports frequency tuning through the UART (DONNÉES) port using simple serial commands. SPI control is not supported by default, but we can customize SPI frequency control for OEM/ODM projects based on your requirements.
Q: Does the “Wideband FPV Receiver (0.2–7.5GHz) with UART Control” support RSSI (Indicateur de force du signal reçu) functionality?
UN: The current version (200-7500MHz) does not support RSSI functionality. Cependant, this feature is already in our development pipeline. RSSI will be fully supported in the next product iteration, which is scheduled for release next month.
T4: Does it support digital video?
UN: Non. This is an analog video receiver supporting PAL and NTSC formats only.
Q5: Quelle alimentation est nécessaire?
UN: The device supports a wide input range of 7–36V DC, compatible avec les batteries LiPo 2S-6S.
Q6: Is it compatible with standard FPV cameras?
UN: Oui, as long as the camera outputs analog PAL or NTSC video signals.
Q7: Do I need to install an antenna before use?
UN: Oui. Always connect the antenna before powering on the device to avoid damage.
Q8: Can it be used without the enclosure?
UN: Oui, but removing the enclosure may affect heat dissipation and slightly reduce performance under high load.
Q9: What type of antenna connector does it use?
UN: It uses a standard SMA male connector.
Q10: Is this suitable for long-range applications?
UN: Oui. With -96dBm sensitivity and proper antenna selection, it performs well in long-range scenarios.
