My HoverBot is grounded. The ducted fans that drive it require nearly 2A, but the TA78080K H-Bridges I'm using have built-in overload protection at 1A. I'd like to use H-Bridges so I can run the fans forwards and backwards. The TA8080's are lightweight and simple to use, so I really like them.
For an interim solution, I'll try using small relays. This won't give the Hoverbot turning ability, but at least it will test the concept until I can replace the H-Bridges.
