Companion Sheild
The entry level shield is labelled The Companion Shield. This is a PCB laid out in the pattern of a solderless breadboard. The holes are single sided, which means that components can easily be removed using solder mop braid, or a solder vacuum tool, if a mistake is made, or components need to be re-used.

Re: Vevor SDS1104 4 channel scope
The weird thing, it that the voltage can go above 5V and below 0V when I turn the encoder real fast.
Demon Today, 01:13I'm using USB voltage from the PC, so no idea how that happens. Maybe the scope loses it's...
