Comparison To Built In RX
Built in receiver (rx) version of the BNF Crazybee F4 Pro 2s flight controller below.
Hi there! Thanks for the great infos about the pinouts! I am wondering where to take 5V power for a crossfire nano rx? Only way will be the led 5V pad, and in case I add an LED, power that from buzzer 5V and LED ground. What do you think?
In theory that should work. I would be curious on the outcome whether or not the buzzer worked fine as a 5v source or if resource mapping would be involved.
My crossfire nano setup on this board is the same as you described excluding the LED, which I may try on the buzzer pad now that you have given me the idea.
I have a XM frsky receiver what pad do I solder to? The IR1 or the RX1?
