I've been looking to do a handheld intel compute stick for a while now but have been held back on how the hell im going to power the thing.
From my research and friends who hooked up oscilloscopes to the m5 compute stick, it needs 5v 3.5A to comfortably power it. This, plus an LCD screen, USB hub, etc. puts any 3a battery bank out of the equation.
So, I decided to use a 7.4v internal battery. I then found a step down regulator (https://www.pololu.com/product/2865), a charging circuit (http://m.ebay.com/itm/TP5100-2-cell...er-Module-2A-18650-Charging-PCB-/181687643612), and a protection circuit (http://m.ebay.com/itm/2S-8A-7-4V-8-...tery-18650-Protection-PCB-Board-/192110391518).
The problem is that I have no idea how to wire these up as I have only used boards that output power to the project and charge the battery on one circuit. Also, how do I power all the other components in the build like the teensy board and lcd from the regulator? If there are any easier ways of doing this please let me know.
Thanks.
