I have several components that draw power from the same source. Some of the components are "sensitive", but draw little current (e.g. MCU, sensors). Other components are "insensitive" (and/or noisy), but draw high or variable current (e.g. motors).
I used to get random resets in my MCU. But I have since separated the sensitive grounds from the insensitive ones (2 main ground lines that join-up later down the line). Also, the more sensitive the equipment is, the earlier it is on its respective ground line. Resets are now very rare.
My question is, does positioning of components matter on the positive line (in relation to effects on sensitive equipment like MCUs)? I'm about to add another component to my project. It's insensitive, and draws a lot of current. So I'll put its ground on the "noisy" line, farther down on the noisy ground line. Does it matter where I put the component on the positive line? Thanks!
