[MinnowBoard] Minimal voltage

Thu Oct 9 21:00:11 UTC 2014

Hahaha,

I already thought about a Power Bank. The problem is that I cant Charge it
and Use it at the same time... or the battery will die very soon. And...
the charger probably can't charge the battery fast enoughs that it
discharges.

Atenciosamente,

Thiago Vasconcelos
