I'm having some trouble using a motor driver board. I'm pretty sure its being driven properly since there is ~3V @ the output v.s. none when its off. However it should be supplying ~2A (rectifier bottleneck) of current, rather than topping out at 120mA. I've tried both outputs, both give the same results.
I'm using this motor driver: http://www.amazon.com/gp/product/B00CAG6GX2/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
I have both output enable jumpers in place, and have tried with and without the 5V enable jumper in. I tie one logic input to 5V and the other to GND. The driver is powered through a 5V DC-DC converter (~2A verified). Am I doing something silly, or is it likely a dead H-bridge?
UPDATE (moved from self-answer): I'm sorry for not being more specific. It turns out that for the 3v motors I was attempting to drive the L298 is not the best solution since it has a few volts drop at high currents, leaving the motors with almost nothing across them if using a rectified 3V power source.
Note: The following is based upon using the L298 on its own, NOT with the original board. I've tried increasing the voltage supply to 6V, and this seems to be working. I intend to increase to a higher voltage, as well as using pwm across a smoothing capacitor in parallel with the motor in order to give a proper output voltage while using a large enough source to account for the drop across the internal transistors in the L298.
