I’m not an expert on these matters…so looking for some advice:
I have two batteries that i’ve used with other non-gadgeteer based robots…9.6v/2200mah and 9.6v/4500 mah. Can these batteries be used safely as external supply to the l298 module?
I have a pair of motors rated between 6 to 24V (max current draw 1.5A) that i’d like to try experimenting with…and wondering if my gadgeteer l298 can be used with these.
L298 page specifies “up to 40V 3A,” so you should be fine with those batteries. The mAh specification isn’t really relevant, as it only measures the capacity of the battery (how long it will last) rather than the voltage or amperage supplied.
@ mhectorgato, If you are going to push more that 2A then you will need the heat sink; here is a well designed solution (imho) [url]https://www.sparkfun.com/products/9670[/url] that uses that IC.
