Kimpok Analog Transmitter KP-T3340B

Kimpok KP-T3340B Analog Video Transmitter – 3.3 GHz FPV VTX with 4 W Output Power

Kimpok KP-T3340B is a 3.3 GHz analog FPV video transmitter designed for hobby builds that need strong output power, stable signal performance, and operation outside the standard 5.8 GHz band. With up to 4 W (36 dBm) output, 16 channels across two bands, PIT mode, IRC Tramp support, and a wide 7–36 V input range, it is a solid choice for advanced analog FPV setups.

This analog VTX works well in projects where reliable long-range-style transmission, compatibility with CVBS analog cameras, and easy field setup are important. Active cooling helps the module handle high-power operation, while the included antennas and cables make installation easier right out of the box.

• High output power: up to 4 W / 36 dBm for demanding FPV applications
• 3.3 GHz operation: a great option for builds using a less common video band
• 16 channels: split across Band A and Band B for flexible frequency selection
• PIT mode: low-emission mode for safer setup, bench testing, and close-range work
• IRC Tramp compatible: convenient integration with supported flight controllers
• Wide voltage input: supports 7–36 V power systems
• 5 V output: useful for powering a compatible part of the installation
• Analog video input: supports CVBS / 1 Vp-p video signal
• Button and LED control: quick setup without a computer
• Active cooling: supports stable operation at higher power levels

4 W Output Power and PIT Mode for Easy FPV Setup

The Kimpok KP-T3340B delivers up to 4 W output power, equivalent to 36 dBm, making it a strong pick for FPV pilots who need more transmission headroom in demanding environments. The transmitter can run in full-power mode or switch to PIT mode, which is especially useful during setup, testing, and powering on near a receiver.

• 4 W transmission power for stronger analog video performance
• PIT mode for low-power startup and safer pre-flight configuration
• One-button power switching between PIT mode and high-power mode
• Mode memory that retains the PIT setting after power-off
• Red LED indicator shows when maximum power mode is active

3.3 GHz Band and 16 Selectable Channels

The KP-T3340B operates in the 3.3 GHz band and provides 16 channels divided into Band A and Band B. This layout makes it easier to match the transmitter with a compatible receiver and fine-tune your FPV setup for the best available frequency.

The factory default setting is Band A, Channel 1 (3330 MHz). A green LED indicates Band A, while a blue LED indicates Band B. The number of LED flashes shows the currently selected channel, so you can quickly check the active frequency without extra software.

IRC Tramp Support and Simple On-Board Controls

The Kimpok KP-T3340B supports the IRC Tramp protocol, allowing integration with a flight controller for easier settings management in more advanced FPV systems. If you prefer a simpler setup, the module can also be controlled directly using the buttons on the housing, which is especially handy when making quick changes in the field.

• Button A: switches between Band A / Band B and cycles through channels
• Short press on Button A: changes frequency within the selected band
• Long press on Button A: switches between Band A and Band B
• Button B: toggles between high-power mode and PIT mode
• LED indicators: show the active band, channel, and power mode

This control method is clear, practical, and hobbyist-friendly. Green flashes indicate the selected channel in Band A, while blue flashes indicate the selected channel in Band B. That means you can configure the transmitter quickly, even without connecting it to a computer.

Wide Input Voltage, 5 V Output, and CVBS Camera Support

The Kimpok KP-T3340B analog transmitter supports an input voltage range of 7–36 V. The manufacturer recommends avoiding operation too close to the voltage limits and choosing a power source closer to the middle of the supported range whenever possible. The module also includes a 5 V output, which can be used to power a compatible component in the system.

The video input supports CVBS analog camera signals or VIDEO 1 Vp-p, making it compatible with typical analog FPV cameras. The 6-pin connector keeps wiring organized for power, ground, video, 5 V output, and the Tramp control line.

What’s Included and Important Usage Notes

The package includes the basic parts needed to install the transmitter in an FPV system. The included antennas and wiring help speed up the build process, but before powering everything on, always double-check frequency compatibility, wiring order, and antenna connection quality.

• Kimpok KP-T3340B 3.3 GHz 4 W analog VTX transmitter – 1 pc
• Connection cable – 1 pc
• Antenna cable / MMCX extension – 1 pc
• 3.3 GHz transmitter antenna – 1 pc
• 3.3 GHz receiver antenna – 1 pc

Always connect a suitable antenna before powering on the transmitter. The antenna should operate in the 3.3–3.5 GHz range and have an SWR below 1.5. Never run the VTX without an antenna, as this may damage the module. The transmitter can get hot during use, so make sure it has proper airflow and avoid touching it right after high-power operation.
