Power supply fo eval board ?

 Power supply fo eval board ?

Hi. I know that this thread may not correspond to this forum, but I hope some users know about this subject.
What kind of light batteries I can use for Phytec KitCON-161 eval board(supply voltage: 8-12V / 500mA). First of all I used 12V from PC.
I tryed a 9V Zinc Chloride battery but the eval board can't run with it. Could it run with an unrechargeable battery?
Thanks.

"Phytec KitCON-161 eval board(supply voltage: 8-12V / 500mA) ... tryed a 9V Zinc Chloride battery but the eval board can't run with it."

You need to understand that "9V" alone is not an adequate description of a battery!
As well as the voltage, the battery has to be able to supply the current requirement of the board.

If you're using a "9V" battery like this:

It is quite likely that it can't deliver 500mA!

If the board really does require 500mA, you will need a set of (at least) AA size alkaline batteries.
A 12V lead-acid battery might be more suitable?

Search for "Sealed Lead-Acid" (SLA) or "Valve-Regulated Lead-Acid" (VRLA); eg,

Note that a 12V lead-acid battery normally gives more than 12V, depending on current charge state.

8 NiCD or NiMH cells should be suitable for the task. They have less inner resistance than alkaline batteries.
