Can you please elaborate on the features of the JP11 jumper and the "current set" resistor. Can that be modified to accept higher charging currents?
The documentation does not have details on this.

Would you maybe have an update on this question? I see maximum charge current pegged at 935mA, and I know that with previous SunControl boards (may they rest in pieces) I was getting up to 1100 mA charge current.
We don't get much sunshine over here so I want to maximize the harvest if at all possible. Every mA counts.

Lutz,
I'm going to have to wait until I get back to the office to look at the schematic and determine what the heck JP11 is! John did not document it in the spec except to mention it existed.
I'm pretty sure it is just a connection to the switch. I'll look at the schematic for the current resistor too.

JP11 is connected to the switch and can be used to add an external switch to turn the 5V USB power off.
I'll still have to look up the current resistor.

So how does JP11 collaborate with the Grove USB control?

Good question. Completely overrules it. If you take this pin to Ground, the 5V Boost is shut off.
