K243 High power reversable speed controller
This is the speed controller used for BoozeBot's 24V 100W skid steer motors. The kit is capable of driving motors up to 500W @ 30V. For an extra $10 you get 4 additional FET's that increase this rating to 1KW. Can be controlled like a servo directly from a radio control reciever or picaxe IC. Can also be controlled by analog voltage or the supplied pot making it very versatile. Great for automating the lawnmower!
Warning - surface mount FET's supplied, mounted on the back of the board. Suggest using solder paste or some other low temperature solder to prevent heat damage. All other components are normal.
