I design a circuit awhile back and sold many pcb;s with my design My design is that you can use 4 wire instead of 5 wire to control the l298 h-bridge board,second you can control PWM seperate for each motor and add a brake if wanted
Its a 2 wire design,i dont know if it will work with EZB it should,it has one direction control and one pwm control and can be set up with total of 3 wires too with 2 wire for direction control and one pwm control ,and if needed another wire for safety brake or overload (stall) brake.
way it set up now it uses 2 wire per motor for direction and en pin for pwm control
my circuit is under $3 in parts
yes i also use the same H-BRIDGE VNH3SP30 very good h-bridge never goes bad if you use a diode board needs to be a very fast diode schottkey type I DESIGN my own H-BRIDGES many times,some over 60 amps per channel
GOOD thing about my circuit you can use PWM for each channel,it helps for 4 wheel design
Also use thermal and over current protection,most h-bridges dont have it,but enable pin is whats used, a simple current to voltage and then a comparator circuit is all thats needed
