This is a neat little one-chip circuit we originally tuned for use with our "SM1" Stepper motors. We've presently sold out of the motor, but this circuit has proved to be a good unidirectional (1-way) driver for small stepper motors.
Escaps back in stock!

Well, the last batch of Escap gearmotors went very fast. Let's hope this batch lasts a bit longer!
Unlike the last set, this set has a higher reduction ratio of 663:1 instead of 362:1. This means it starts turning 0.46V (!) drawing only 3.3mA (!!)
It's a 3V rated motor, but our tests show that they spin quite nicely at 5V, drawing 4.2mA free (!!!) at 22rpm. Don't know what the stall current draw is, as we're scared to strip these delicate gears, but it's greater than 150mA. Check them out!

Here at Solarbotics, we like to eat well.
