Important Tips

• When flashing ELRS Bind phrase, the target for the AIO is EP1/EP2
• We strongly recommend you "Upgrade" to Betaflight version 4.5.3 to fix the intermittent issue of flip over after crash not shutting off after rearming to take off
• Onboard VTX only powers when the battery is plugged.
• VTX output defaults to low power when disarmed — you can change this via SmartAudio.
• Visit the Betaflight configurator and select “Can’t find my USB device” if your controller isn’t recognized initially 
  

Package Includes

Frequently Asked Questions

Is this controller compatible with Mobula6 2024?

Yes. Designed to replace or upgrade FCs in 65mm 1S whoops like Mobula6 2024 and Mobula6 ECO.

Does the onboard VTX work without arming?

The VTX defaults to very low output when disarmed. You can set your desired VTX power level using SmartAudio.

Can I flash firmware via ExpressLRS?

Yes — this board supports ExpressLRS firmware flashing via WiFi and is fully compatible with ELRS V3.x.x TX modules.
