Experience from scoop: output voltage 4.6? and not good to short!

Hardware

Hi,

we are experimenting with the scoop. First an user error that others may benefit from knowing: We used to have a couple of 10F capacitors over the input terminal of our device, when using these together with the scoop bad things happen. My guess is that the scoop tries to deliver a huge current to charge these as fast as possible, and thus burning some of its internal scoop-circuitry in the process. Lost two scoops this way before we got wiser. Remove the caps, everything appears in order.

Secondly, the voltage out is usually measured to 4.6 or 4.8v which seems to be higher than specified. Any ideas about this?

Regards, Gaute

Hi @gauteh,

Measuring 4.6-4.8V on VOUT is definitely not normal. Is there any chance something else on VOUT is pushing that same voltage backwards into the Scoop or to VIN > 24V?

Hi,

These were with 6V input. We think we measured before connecting our dubious electronics onto it, but we will report back if we experience the issue again with a pristine scoop.

Thanks, Gaute
