4. Simple frequency matching
5. Small size (TX: 47.3mm x 32mm) (RX: 43.8mm x 37.8mm new version), low power consumption
6. For simple frequency change, the starting frequency can be set through the serial port, and the 4 frequency points can be cycled by pressing the button
7. High image quality and low signal interference rate

Specification

1. Transmitter frequency range 100MHz~2350Mhz, 2.5G~3.3G
2. Receiver frequency range 100MHz~2350Mhz, 2.5G~3.3G
3. Default frequency range 400-900Mhz
4. Default power amplifier: 3-watt
5. Power supply 12~18V
6. Video input source: AHD / CVBS camera
7. Frequency selection method: one button (four frequency preset loops chosen, the interval between the four frequencies is 20Mhz. for example, 500Mhz, 520Mhz, 540Mhz,and 560Mhz.)
8. Without our default PA, the default setting is 1dBm, but we can increase the dBm according to the customer’s requirements, and the maximum is 15dBm.

TX, RX protocols commands

How to modify the transmission frequency through the serial port or digital transmission?

Baud rate: 115200, check bit: NONE, data bit: 8, stop bit: 1, flow control: NONE

Command:
(1) Set base frequency: bp:500\r\n
(Description: bp: + frequency + \r\n)
(2) Frequency range: 100MHz~2350Mhz, 2.5G~3.3G
(3) Set host slave: status:0\r\n
(Description: status: + host or slave + \r\n, 0: represents host, 1: represents slave)
(4) Button function: Each time the button is pressed, it accumulates by +40MHz, and the indicator light can display 9 gears.

Weight

TX RX board weighs 9 grams.

FPV video transmitter and receiver has two types, one is for analog CVBS 720p video, and another type is for digital HDMI or CVBS HD video, most adopted COFDM encoder and decoder technology. FPV digital video transmitter and receiver.

FAQ:

Question: Can you make the analog FPV transmitter and receiver have a relay/repeater?

Answer: This is an analog model, there is no relay or repeater in the middle. If you need a relay or repeater for your FPV transmission system, please check the below model, which uses the COFDM digital transmission system, it can have a repeater. 3W PA 50KM

Question: Is the frequency related to the hardware? Do I need to change the hardware to change the frequency?

Answer: Different operating frequencies require corresponding power amplifiers and external antennas.
If we do not consider the power amplifier and antenna and adjust the operating frequency, the hardware of our transmitter and receiver boards are the same.

When placing an order, tell us the frequency you need and we can modify the working frequency for you. You can also change the working frequency yourself by sending commands through the serial port.

Question: Can you customize the FPV video transmitter frequency 88Mhz-108Mhz and 470Mhz-880Mhz at a 1-watt Power amplifier?

Мudole Driver Amplifier, Type: Power Amplifier, Supported Modes FM, Frequency Band: FM & UHF, Frequency:88-108MHz, 470- 880 MHz or Multi Bands, Power:1W, Connector: SMA

Answer: No problem, we can customize it for you according to your demand points.

Question: Can your FPV video transmitter VTX avoid interference from drone anti-gun jamming?

Answer: The anti-gun interference range of most drones is 433MHz, 868MHz, 915MHz, 1GHz to 1.4GHz, 2.4GHz, and 4.9GHz to 6GHz. The operating frequency range of our model FPV VTX VRX can be customized according to your needs. Therefore, we can set the operating frequency outside the above frequency range.

Question: Can you make a 3.3G repeater for your FPV VTX and VRX module?

Answer: Currently, we do not have repeaters for analog video transmission, only repeaters for wireless digital video transmission, please see here. https://ivcan.com/drone-repeater-solution/

Question: Can you make it a 10-watt PA power amplifier?

Answer: The largest power amplifier now is 4 watts. The operating temperature of the transmitter is already very high, so it needs to be installed on a frame made of aluminum or use the rotor of the drone to dissipate heat.

Question: Does it switch frequencies using FHSS technology, or perform manually in a given range?

Answer: This analog FPV VTX does not support FHSS (frequency hopping spread spectrum), but it supports changing frequency by a button on the VTX or sending the change frequency command via the flight control to our VTX serial port.

Question: Can you make the frequency like this? 1050 Mhz, 1075 Mhz, 1135 Mhz, 1235 Mhz or 1350 Mhz.

Answer: Without Power Amplifier and antenna, the user can change the frequency to meet your demand.
If you need the power amplifier and antenna to support, please tell us when you place the order. We will customize them for you before shipping.

Question: Do you have VTX VRX for 500Mhz?.

Answer: This analog FPV VTX VRX we can customize 500Mhz frequency for you.

500Mhz range is suitable for long-range FPV systems prioritizing reliable signal over high-definition video. We also can recommend our COFDM digital frequency transmitter and receiver.

Quesstion: How do I access the serial port? Should I just use an RS285 and connect the cables?

Answer: please use the USB to TTL converter tool to connect to your computer.
