MultiWii

Hello.

What pins used for SERIAL0 on board based on ATmega32U4 MicroWii?

I want to use OSD+Blutooth+USB at same moment, so I am going to use SERIAL1 for bluetooth and SERIAL0 for OSD.
This board have special pins that associated with SERIAL1, but I could not find pins for SERIAL0.

In config.h board selected as "FREEIMUv043" and uncommented "#define A32U4ALLPINS"

can you post a product photo or link of your board

The ATMega32U4 provides only one USART namely SERIAL1 and one USB port which is implemented in hardware and called SERIAL0 only by multiwii.
Thus, there are no USART-pins called SERIAL0.

In general, I don't recommend any PROMICRO/ATMega32U4-based flight control board if you intend to
- make use of more then one USART/SERIAL,
- connect a GPS device,
- use telemetry,
- expand the code with own code or
- be safe for future developments (because the available FLASH is quite spare)

Forget that board and buy an ATMega2560-based one which better fits to your purpose.
It costs only for a few dollar/euro more.

my sentimant exaclty, just not worth wasting your time for the difference in cost vs capability , the sooner you cut your losses to better
