MotorFish is an intelligent driver for one stepmotor or two brushed motors.
MotorFish is able to drive a bipolar stepper motor or 2 brushed motors with a current up to 2.5 Ampère per phase.
An autocalibration routine is able to compensate for any sensor's non-linearity or small positioning errors.
Unline standard low-cost drivers, in MotorFish all parameters are configurable via software, comprising the max motor current.
The board provides a small switching converter able to get the 3.3 Volt needed for on-board electronics directly from motor's voltage; you don't need to provide any additional low-voltage supply.
Even without software patching, the driver is able to compensate for step losses, walking up to requested position if possible.
MotorFish uses a performant 32 bit MIPS controller to handle all motor's and interface operations.
By aid of a custom bootloader you can program the controller with the well-known Arduino IDE (or our FishIDE, of course!)
The ability of MotorFish to be completely re-programmed allows to handle any kind of motor control needs ; you can use to drive a stepmotor or to precisely control the speed and direction of 2 brushed motors.
