L298N + picaxe28x1 (axe020) could work?
April 13, 2009
recently i found that the problem with my project is that the motor consumes more than 1 amper (with no load),
because i tried using the L293D it didnt really work well (that's an understatement).
since i would really like to save the trouble of building my own high current H-bridge, i thought the L298N can do the job.
so after measuring i found out that the motor consumes:
1.5 amper with no load.
2-2.5 with the nominal load.
i chekced the L298N datsheet and saw it is designed for max 2 amper nominal current so my questions are:
1. will it be able to work with 2.5 amper or even 3 amper with good heat dissipation (from your experience)?
2. will it connect to the picaxe28X1 like the L293D did?
i checked the connections of both ICs legs and i am not sure they are identical:

thanks in advance, shaked.
