The spec said 500mA/channel. I would think a 6V motor starts around 1.5-3 amps for a tiny one.
And motors give the driver circuit a nasty kick-back, so the driver would have to be hardened against that, I'm not sure if this one would be able to take it.
ckiick - The initial idea is to drive LED matrixes, we haven't tested 6v motor with it. As Oracle comment it might be too high load to mess the driver circuit. May be a separate power and stronger driver could be included, we would need to weight the options.
The price we targed would be about $15-25 ea., preferrally sold in 5 or 10 pcs bundles.
Actually, Seeedstudio since you're developing so many innovative products and always looking for suggestions, I do have an idea.
Can you make a motor shield that can handle cheap hobby motors (around 3 volts, 3 amps)? Most of what I see available is built around the L293D, which has a maximum current of about 0.6A/channel and doesn't play well with motors under about 6 volts, which simply won't work with the cheap motors.
I like the software interface for ladyada's shield (as simple as motor.setSpeed(100); motor.run(FORWARD) as well as a similarly simple stepper motor interface.
The only drawback to ladyada's shield is it can't drive my toy motors.
I meant as a separate shield, not part of Rainbowduino.
3V, 3A should be good, the guideline I was looking at was something like the Tamiya twin-gearbox motors and 3V, 3A is perfect for them. I'd also like to see support for 2 steppers like the ladyada shield.
Also, Rainboduino looks really nice. I was going to build the same around MAX7221 chips for the red-green matrix I bought from you, but I haven't had a chance and the perfboard pattern I normally use isn't suitable. It would be so much easier to just buy your shield instead of making mine from scratch.
I just sampled some solenoids that are 12V 600mA, and if they switch fast enough, I'll be interested in driving a largish number of them. A strong "driver shield" will be my second order of business.
