ULN2803 DC Motor Driver Assembled Edition
Description / What you can build
The ULN2803 DC motor driver assembled edition comes with four preassembled channels and ULN2803 integrated circuit at the same time providing the possibility for custom/DIY implementation. This is an example of what you can build with ULN2803 assembled edition development system (pictures below).
As you can see, the implemented motor driver supports multiple types of DC motors.
It supports a variety of algorithms for motor control: stepping, microstepping, PWM etc.
With additional LED matrix, software development is simpler.
For additional information, read our guidance, the possibilities are great.
