<![CDATA[A power "platform" for Arduino Pro Mini's?]]>I have a number of sensor projects that sit within the nice footprint of a Pro Mini. Now I want to find a kind of universal power platform--hopefully small--to power them. So far, what I came up with was this, which runs the Pro Mini from 2xAAA batteries, and where the Pro Mini (and whatever the project built on it) simply "plugs in" to it:

Is there anything better? Ideas? Comments?

The three on the left are very close to the size of just 2x AAA batteries. One of the two on the right uses a JST-XH connector. The next iteration of the LoRa shield PCB will have that JST connector plugging in from the side so that it doesn't interfere with the FTDI connector as much. I think that for connecting to custom made PCB's, the JST connector doesn't actually make much sense, but it would make sense if plugging into a COT power pack.

Then, just use double-sided tape to secure the Pro Mini to the power pack, and done.
