Unfortunately I cannot change the review so I'm doing a new one. Both problems that I had were not related to the board, but with other items. I had a problem that when I spin motor 1, motor 2, 3 and 4 reacted also. But I found out I had a lose capacitor on my ESC. This was fixed and worked like a charm. And the GPS problem I solved by putting Cleanflight 1.11 in. The current version is not stably communicating with the GPS. So all in all the product is good. It includes all the latest sensor available (MS5611 baro, gyroscope, acceloremeter, magnetometer), it include the cables, but I missed one cable for the GPS connection, so I dissoldered the heading and soldered the cables directly to the board. Make sure you use a BEC for greater reliability.I bought this one to replace my old Multiwii Pro on my quad. Because I wanted to jump to 32bits world but for sure was not worth it. Board connected to PC correctly, but after made all connections correctly, GPS is recognized but is glitchy and never keep a fix. And worst of all, if I run 1 motor manually, there is interference to other 3 motors and they run as well. It means that during normal operation, the right command is not sent to the right ESC and the Quad is uncontrollable. I tried using ESC BEC, and also an external UBEC and had the same symptomps. I know how to make power connections and to avoid double supplies so it is not a connection problem, it's a bad product. And it costed me double because of brazilian taxes. Now and put back my multiwii pro and all is working. I don't recommend the product.Great flight controller for a 250 sized FPV racing quadcopter. Easy to setup with cleanflight and works as a Naze32 equiv flight controller.
