My recollection of MOV specifications is the are often rated for AC operation I.e. In the US we might use a 130Vac MOV. While others are rated for DC operation. For most folks it is probably wise to follow those ratings. If you are really into MOV.s then you look to the curves. I do not mean to imply that AC rated MOVs a different from DC rated MOVs, they are both physically the same parts, its just how the catalog presents the specifications.

@nca78 said in Combining orders at OpenHardware.io?: Just make a paypal donation of the PCB price difference to MySensors for that. Maker of PCB will lose their share but it's pretty small and it ends up given as donation to MySensors most of the time. Excellent idea!

You can use this category (general discussion) if you like. Or try the openhardware category, if it is open to new threads. It is open to me, but that might be because I have admin privileges.

@yveaux thank you for reply, i dont have any arduino with led to test this :) all boards are in use and without led may be i'll order few to test this at some stage.
