The motors controller is designed to control up to four brushed DC motors. It uses 32-bit ARM-based microcontroller. The device is suitable to control drives of mobile robots with two or four wheels. There are also implemented a lot of other features, so the device can be used for other purposes as well.
The presented set of power supplies was made in 2010 and it contains two devices. One of them is my first electronics construction. The second one is a modified computer ATX power supply. This post is focused on the first device what means power supply with flexible voltage and maximum current fuse.
The assumptions about created power supply were simply: practical construction and low cost.
