Radio Transmitter Modules for FPV Drones: Types and How to Choose

When it involves radio management for FPV drones, the transmitter module performs a important function in making certain a secure and dependable connection between the pilot and the drone. In this text, we’ll take a more in-depth take a look at the various kinds of transmitter modules out there for FPV drones and supply some steerage on how to decide on the best one in your wants.

Types of Transmitter Modules

There are two predominant sorts of transmitter modules utilized in FPV drones: analog and digital. Analog modules use frequency modulation (FM) to transmit alerts, whereas digital modules use quite a lot of encoding and modulation methods, similar to frequency-shift keying (FSK) and unfold spectrum.

Analog Transmitter Modules Analog transmitter modules are common for his or her simplicity and low value. They are sometimes utilized in low-budget FPV drone setups and for short-range flying. Analog modules are suitable with most FPV receivers and provide good sign vary in open areas, however their sign high quality can degrade in areas with plenty of interference.

Digital Transmitter Modules Digital transmitter modules are extra advanced and costly than analog modules, however they provide a number of benefits. They use superior encoding and modulation methods to supply a extra secure and dependable sign, even in areas with plenty of interference. Digital modules additionally provide longer vary than analog modules, making them supreme for long-range FPV flying.

How to Choose a Transmitter Module

When selecting a transmitter module in your FPV drone, there are a number of components to think about:

Frequency Range: Make positive the module operates inside the authorized frequency vary in your nation. In the United States, for instance, the authorized frequency vary for FPV flying is 5.8 GHz.

Power Output: Look for a module with an influence output that’s appropriate in your wants. Lower energy modules are sometimes used for short-range flying, whereas larger energy modules are higher fitted to long-range flying.

Compatibility: Make positive the module is suitable along with your FPV receiver and different radio management parts, similar to antennas.

Price: Consider your funds when selecting a transmitter module. Analog modules are typically cheaper than digital modules, however they provide much less superior options.

Main Suggestions

Here are some common transmitter modules used within the FPV drone group:

  1. TBS Crossfire: The TBS Crossfire is a digital long-range transmitter module that’s common amongst FPV fans for its dependable sign and lengthy vary.
  2. FrSky XJT: The FrSky XJT is a digital transmitter module that’s suitable with many FrSky radio methods. It gives dependable sign high quality and good vary.
  3. Flysky FS-iA6B: The Flysky FS-iA6B is an analog transmitter module that’s common for its low value and ease. It gives good sign vary for short-range flying.
  4. OrangeRX DSMX/DSM2: The OrangeRX DSMX/DSM2 is a digital transmitter module that’s suitable with many DSMX/DSM2 radio methods. It gives good sign high quality and vary.
  5. ImmersionRC EzUHF: The ImmersionRC EzUHF is a digital long-range transmitter module that gives wonderful sign high quality and vary. It is a well-liked alternative amongst long-range FPV fans.


The transmitter module is a important part within the radio management system of an FPV drone. Choosing the best transmitter module can significantly have an effect on the reliability and stability of the connection between the pilot and the drone. Consider the frequency vary, energy output, compatibility, and value when selecting a transmitter module in your FPV drone, and ensure to pick out a good model with a confirmed observe document of high quality and reliability
