is it of Non shorting type????

12-03-2005, 03:02 AM
No , if you give 1,1 to input transistors will blow!!!!!!!!!!

Sorry man, then its of no use to me, when i reset my controller all the pins go high means "BLAST of Transistors"

These are mainly intended for those who wants to use a cheap rc cars circuit with high power motors, so in that case it would not be a problem. You just need to buy a car for 180-200 rs take its circuit out and join some pins with this circiuts' input, and run big motors.

Yaaaaa, thats good for those people who need high power rc circuits at low cost, its good idea.

Do you use yahoo or msn messenger ??
Chatting on forum is something odd...

Ok, and what is the size of full board, what is max voltage it can take??

12-03-2005, 03:19 AM
Its about 8 cm x 5.5 cm, Max 16 V, 2 motors, also could be used to control bipolar stepper with l297

12-03-2005, 03:20 AM
Another good idea, But the size is toooooooo big yaar...

12-03-2005, 03:22 AM

the price is also cool...
how r u goin to send it???????

12-03-2005, 11:16 AM
Why do u need that big (5cm x 5cm) dual h-bridges when u can get it in a single chip L298. You can give 1 1 input to them to cause breaking effect in the motor. Each h bridge can drive 2A and u can get 4A by connecting 2 h-bridge on L298 in parallel. And L298 costs around Rs.120 .
Please let me know if the big h-bridge board has special features or extra advantage.

does it has any advantage over the
conventional and reliable l298.......
and is it made up of ic's or discrete components?
