Think & Create

Resistors are essential parts in a circuit. When we prototype our ideas, we need various kinds of them. But it is annoying to put the resistors back to their original pocket after the experiments and it is a bit wasteful to put them in trash bin. With this digital variable resistor, the problem is solved.

This digital variable resistor consists of 24 1% SMD resistors. They are 1,2,3,3 in each order of magnitude and connected serially. Each resistor can be shortened by a switch, which means the overall resistance can be any value from 1ohm to 1Mohm. The resettable fuse will protect the whole board from over current.

With this digital variable resistor, the resistance can be adjusted in circuit while its value can be read directly. It is extremely suitable to be applied as the current-limiting resistor, feedback resistor, etc.
