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.
Lower gear ratio motors!

We're happy to announce another variant of gearmotor. Like the GM2/GM3 but with a gear ratio of 143:1, they run approximately 175% the output speed! - these are ideal for applications like minisumos, linefollowers and other wheeled devices. Check the "New Items" listing on the left side for details, or view them directly here: GM8 (offset) or GM9 (90 degree)

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 […]
