Description

Coarse/Fine potentiometer control.

This board implements coarse and fine controls using a single-gang potentiometer (VR1) for the coase control and a dual-gang potentiometer (VR2) for the fine control. Generally, VR1 should be 10-20 times higher value than VR2. For example if you choose 100K for VR1 then you would choose 5K-10K for VR2. The total maximum resistance will be VR1+VR2. The board is designed such that teh shaft centers are 30mm apart. Connection to the main circuit is via a 3-pin header.
