Description

StePPer driver for model railroads

HI, StePPer is a project based on a attiny85. It is a stepper driver for a unipolair stepper motor like 28byj-48.

it can be used as switch engine or as a continue motor with high torque and very low rotation speed.

It has many parameters that can be set, like position speed.

Besides the button on the pcb you can connect extra buttons.

It has ISP connection so you can reprogram the attiny85 for updates using a standard arduino uno as ISP programmer.

It has a DCC decoder build in so can be controlled by DCC commands. (for model railroad applications.)

Have fun

Rob
