Video Transmitter TX Module
- We can adjust the RF bandwidth of this model to 2M/QPSK and increase the receiving sensitivity to -98 (actual), which is 7dB higher than the original sensitivity. This will more than double the corresponding transmission distance.
- What UAVs care about is the size and weight of the Video Transmitter TX Module. The weight of the whole machine can be within 100g.
- The Wireless Video Transmitter TX Module transmission itself has a delay of 75ms
- One-way COFDM video transmission, mainly used for FPV(First Person View)
- SD video transmission, RF bandwidth up to 2M, end-to-end delay of less than 200ms
- Default 3W PA support 50km (LOS)
- The default working frequency is 595 Mhz, and we can customize 170~860 Mhz
Video Receiver RX Module
RF Wireless Video Receiver Dimension 70×80×15mm
Here is the FPV video transmitter with a metal case.
Why this model is better than COFDM-912T as an FPV video transmitter?
The difference between COFDM-912T and FPV1887 wireless video transmission is
- The FPV1887 video transmission video delay latency is small, only 120 milliseconds. COFDM-912T delay is more than 400ms.
- With different modulation bandwidths, with the exact video resolution, the FPV1887 video transmission only requires 2MHz bandwidth, while COFDM-912T requires more than 6MHz.
- FPV1887 has a longer-range transmission distance, stronger diffraction performance, and anti-interference performance. Because it uses a narrower bandwidth, it has higher receiving sensitivity and takes up fewer resources.
- Smaller size and weight: Compared with COFDM-912T video transmission, the FPV-1887 video transmission adopts a more advanced encoding and modulation scheme, with lower overall power consumption, smaller size, and a weight of only 80g.
- The unique 45-degree RF antenna design is more suitable for the FPV and is more suitable for the high-speed flight angle of the FPV.
- The video transmission of this FVP1887 is suitable for vehicles with a flying speed of about 120km. For vehicles with higher flying speeds, the video delay will appear larger and the control will not be so good.
- More amplifiers to choose from 1 watts, 2 watts, 3 watts, and 4 watts. (default 3-watts support 50km)
FAQ
Question: Why does powering on the transmitter cause its shell to become very hot?
Answer: First, we tested this circuit board at temperatures of minus 40 degrees and 85 degrees. The hand feels very hot and will not affect the normal use of the transmitter.
Second: There are two reasons why the case temperature is a bit high:
1. In order to be waterproof, our casing does not have heat dissipation holes and fan holes.
2. In order to support 50 kilometers, we have a built-in three-watt amplifier. A power amplifier requires a cooling fan. The chip and board of the power amplifier are close to the metal casing to transfer heat.
If your project doesn’t need waterproofing but allows heat dissipation holes, we can add them to the shell to make it less warm.
Question: The shell of this transmitter looks very heavy, and not suitable for installation on a drone that needs to be lightweight, right?
For this product, we mainly provide transmitter boards and receiver boards or modules. Users can customize the case or install it on their own device or aircraft.
This optional case is convenient for customers who need it to take samples for testing. There is a case to protect the circuit board from damage during transportation and testing.
We also use lightweight and cheap aluminum, which is processed by a CNC milling machine. The shell’s protrusion is not just for looks; it improves the transmitter’s performance by dissipating heat more effectively.
