I have purchased two complete 2 axis gimbals, both on line purchases. One from BangGood and the other off of Amazon. Neither of them seems to work correctly. I have tried using the SBGC to tune the two controllers but am having no luck there either. I am not even sure if I have an 8 bit or 32 bit board. How can you tell? I keep getting connection errors due to firm ware incompatibility. When I try up dating the firm ware I get errors on that as well.
