Looks exactly like in the photo. Flight controller works functionally. Firmware is updated without any problems. Firmware omnibus4sd, if i’m not mistaken.

Functioning perfectly, I connected the receiver and managed to configure it, but I still need to put the sc and the motors, but on betaflight it is working and the seller sent me the firmware updated in my email.
