can anybody post a full datasheet for the new motor control. I am wondering what the maximum voltage motors it will be able to handle. I am thinking about pre ordering a few depending on the specifications.
Link to l298n data sheet
Absolute maximum ratings are as follows;
Vs = 50v
Vss = 7v
Vi, Ven = -0.3 to 7v
Io = 3A (non repetitive), 2.5A (repetitive)
Vsens = -1 to 2.3v
Ptot = 25w
Sparkfun host a datasheet here.
There is also a datasheet for the L298n in my Datasheet Repository
It's a two channel 2.5A motor controller based on the L298n chip which is a 2 channel 2.5A h-bridge, not 4 channel.
In theory you could run 1 motor by putting channel 1 and channel 2 in parallel however you would need to ensure that both channels are only enabled in the same direction and at the same speed to avoid damage.
for the l298n

The outputs intended for 2 motors are referred to as channels because they are reversible and you can also induce a high frequency drive through pulsing the enable pin.
Looking at the data sheet the l298n doesn't have a internal bridge to combine to channels so you must manually wire one motor in parallel. Like Rich mentioned that means testing that both sets of channels are the same polarity with a meter before wiring your project together to avoid the sudden death of your H bridge. If I can recommend any brand it would be sparkfun, because they over build the unit with larger components to protect the H Bridge from damage , but they cost more. The EZ-Robot.com H bridge still works great and provides savings over the sparkfun. It really comes down to price your willing to pay and if you can wait for it.
