Hi Folks,

I am about to make an H bridge myself using L298N to drive 2 motors. I have been searching to find a good diagram, with all the parts needed so that I can buy the parts, or find it from my stock and get things done.

Does anyone here have a complete diagram for this with Protection diodes and Capacitors and their values.

Google isnt helping me. :-/


P.S: Not asking to be spoonfed, but I am making this thread after hours of googling wihtout any satisfactory results :-/

Have you looked at the datasheet, more specifically page 6?

For your convenience, the link is here.

Basically, you need 8 diodes ( 4 per channel, of type FR), and just 2  x 100nF caps (at +Vs and +Vss) and 1 resistor (Rs).

Rs has to be calculated as per datasheet instructions.

On a related note, the "multiwatt" package- see pic below- is "breadboard-unfriendly".... iirc those two rows of pins are staggered and you'll need to do some careful bending, or solder leads on instead, maybe.

Please don't PM for technical advice. Firstly my advice is sometimes wrong, and second, in the forum you get a broader, more timely, range of responses.

I advise against trying to breadboard an L298N. Aside fro the breadboard-hostile package, a breadboard isn't meant to handle the sort of currents that the L298N can. Buy a cheap L298N board from eBay instead.
