[Help] Power distribution from a 12v Li-ion battery
in Robotics
I am building my first robot and am scratching my head about power. I am a complete beginner so please bear with me ![:) :)](https://forums.parallax.com/resources/emoji/smile.png)
I have a small 11.1v 1500mah lipo battery powering the motors at the moment, a powerbank for the Raspberry pi.
At the moment my audio is a cheap usb speaker and I am about to swap it out for a 12v audio amp pcb, here lies the issue.
I assume just using a splitter on the battery output would be bad, and the output would need to be regulated or fused? I cant find any small premade pcb's that would fix this either.
Any suggestions for this newbie?

I was thinking something pre-assembled and no bigger than a credit card.
The only way to gain the skill is to make your own board, and a power distribution board is a good starting project. It's a relatively simple circuit using large easy to work with and solder components. Give it a try!
The 3 boards above the Propeller Activity Board are 3" x 1.75" boards I use for prototyping circuits. The left one has one pad per hole, the right is a "dip strip board".
The center board is a dual MCP3208 prototype from an earlier project.

Note: I'm not vouching for this seller, just pointing out the type of board I use.
My go to is the Parallax circuit overlay boardhttps://parallax.com/product/32999... reason? Incredibly easy to solder... not sure why but it is just a pleasure. If that won't work I like the Vero one sided strip boards. You can easily cut the strips with a knife, dremel or cnc. They are a little harder to solder. I use liquid flux, which makes it a lot easier.
The two sided Vero boards are nice, but the holes are not plated, so you have to make sure you make continuity where you want it.
