Hy all i have a problem with the V2 board i powered it from a ubec 5v the led';s blue red are on and the rx and tx ar on continnuos i can';t arm it and have problems to connect to mp. I think thatt maibe is posible this problem because i have onli 5v instead of 5,5v so i think that to not invest more money is to setup the UBEC to 6v and put a rezistor to reduce voltGE to 5,5v
