Mini Power!


#1

Hi guys,

Apologies if this has already been raised.

I’m thinking about converting my the components I got with a FEZ Mini robot into something new. The new project doesn’t have any motors, in fact it’s just a FEZ Mini, some low power sensors and a LCD screen, and so doesn’t have a large power requirement. It does have a requirement to be as small as possible however. The battery pack (4x AA) is pretty bulky.

What’s the best way to go for a smaller way to power the FEZ Mini?

Ta
Andy

Lithium Ion Battery Packs are the way to go if you want high power with small size.

have you measured how much current you need, Do you use Hibernate mode of chip? Do you have any threads that are running in a tight loop rather than sleeping etc .
Rough estimate maybe 50mA so 1500mAH Lithium should give you 30 hours
