Hey Folks, and Happy Wednesday.
I am attempting to make my Overo+Chestnut43 battery powered, my plan is on using a 3.7 LiPo with a booster/charger circuit.
I know that I need 5V. I also know that my wall adapter is rated at 5V, 1000mA. So far, so good.
I cannot find any documentation on the specific power requirements. My question is can I go lower than 1000mA? How much? How can I tell on my own? (Yes, it's a 3-parter!)
Thanks, all of you. I'm getting quite an education here.'.

I have an Overo Sand w/Chestnut43 board. When I checked my power draw
from a 12 V supply through a linear 5 V regulator, I got a total draw
of 600 mA with the 4.3" LCD on, 300 mA without. However, I am also
powering a 3.3V regulator from the 5 V line, and 90 mA for a GPS.
So, the draw for just the board and Overo should be ~200 mA. I will be
doing more testing on the combined draw from a 7.4V Li-Ion battery soon,
but I'm not sure when.
