News: TBS Crossfire Micro TX V2 Module

The Crossfire Micro V1 was on sale at half price recently, some of us was right to guess they were preparing for the release of a new product – the Crossfire Micro TX V2 module. Let’s take a look at what’s new.

The TBS Crossfire Micro TX V2 allows you to use the 868MHz / 915MHz frequency for your control link. It’s an external module that you can install on many radios with an external module bay, such as the Radiomaster TX16S and Jumper T18.

At first glance it might look similar to the original version, but there are a few changes and improvements. New to Crossfire? See my setup guide.

Higher Output Power Potential

The V1 originally had a max output power of only 100mW, but that was later increased to 250mW in a firmware update.

It might be disappointing for some to learn that the Crossfire Micro TX V2 has the same maximum output power as the V1, currently set to 250mW.

However, according to Youtuber Livyu, the new V2 module actually has a new Skyworks RF amplifier IC, which is capable of 27dBm (500mW). So I wouldn’t be surprised if the max power will be increased to 500mW in a future firmware update for the new Crossfire Micro TX V2 module.

Nondetachable Antenna

The antenna is no longer easily detachable. This is to comply with FCC rules (antenna should not be removable in the device).

However, the “integrated antenna” is simply just a cap over the SMA connector. If you remove the screws and plastic cap, underneath is a standard SMA connector and you can still remove it and use whatever antenna you prefer.

USB-C Connector

Not a biggie, but it’s nice to see them replaced the Micro USB Port with USB-C. Not sure why we still use Micro USB in flight controllers, it’s easy to break, and you have to carefully line up to insert it. USB-C solves all these problems.

Redesigned PCB

The schematics of the PCB has been redesigned/improved. Hopefully we might get even more features from future firmware updates. According to Livyu, the V2 also has more filtering and higher tolerance to interference from neighbouring frequencies, results in better performance.

    Arthur I had the same as you.
    Official support reply:

    Good day! Thank you for your email.

    Please update Crossfire firmware to 3.77 or above. This is a bug and fixed with 3.77 firmware.

    So i upgraded to beta 4.0 and now i have 1W choice !

    Micro TX V2
    Dyn Power = OFF

    Max Power 250mW
    Telemetry Page shows TPWR = 100 mW
    Max Power 100mW
    in Telemetry Page TPWR shows 25 mW
    Max Power 25mW
    Telemetry Page TPWR shows 10 mW
    what the happens ?

    I went from a R9 to a tbs crsf TX lite and when running at a lower output power I notice a significant difference in range. It also depends a lot on the rf interference in ur area (in my area it’s rly bad) . If you want to go from the R9 system to crsf I recommend getting the TX lite since it will provide similar if not more range than what you are use to.

    Why when Crossfire has it’s module on sale do people think a new model is coming out, yet when DJI has their digital FPV system on sale no one is thinking the 2nd gen. system is about to be released?! And, on July 31st, yeah not many days until then, it’s been a year since the 1st gen system was released. I’m just saying, expect it! ;)

    Do you have any idea how far 500mw will get you with Crossfire? MILES! lol Why anyone would need more is beyond me. Probably why Crossfire is sticking to 500mw! lol

    1. Benny Bryant

      “Miles” of range is simply a method of comparison . You rarely fly in ideal conditions and more miles of range translates into better penetration through obstacles at the short ranges you usually fly at .

    Noiss… how would the performance of this (at 500mW) compare to the R9M Lite Pro at 1000mW? CRSF still better because of implementation? I read somewhere that R9 uses a higher telemetry output power compared to CRSF. I’m enjoying my R9 but that Tango 2 is looking very compact, will it be as good as my 1000mW?
