By simply updating the firmware on your Crossfire Micro TX module, you can increase the maximum output power from 100mW to 250mW. I will show you how in this post.
Once updated to FW2.4, you will be able to select up to 250mW instead of 100mW in the LUA script menu.
This is great news. I saw some DIY tutorials going around on the internet, showing you how to “unlock” more power in the Crossfire Micro by removing or adding some tiny components on the PCB. I am too lazy for that :) Now you don’t have to do it, just simply update the firmware and it’s done!
With the increase in transmission power, not only you are going to get about 30% more range, you will also get better penetration when flying behind obstacles.
How to Update firmware?
Connect the Crossfire module to your computer, launch TBS Agent, and click the “Update” button. You need to update to firmware version 2.4.
It takes about 3 mins to complete.
See section “How to Update Crossfire TX firmware” in this tutorial for instructions.
Do we need to rebind receivers too?
Yes, like always you need to rebind after updating firmware on the Crossfire TX module. See this part for instructions how to bind TX to RX.
Do we need to update LUA script / Taranis too?
No, the new 25mW, 100mW and 250mW options will appear automatically after the Crossfire firmware update.
What if I have already done the DIY hardware mod no the Micro Crossfire for increased power?
It’s okay, you can still update the firmware, but you won’t be able to select lower output power and it will be locked to 250mW.
