Allstar Pocket Node
I had been thinking for awhile about building a small node that would fit into a Raspberry Pi 3 case to use in the car and when out and about. I came across WX8L's blog about a node he made and decided it was time I made one.
Here is a link to his post WX8L Blog. The only real difference with mine is I used the type of CM108 soundcards that are easily found on eBay. It was longer than the one in the blog post so I cut some of the board from each end.
I have been using this with a 5V 2A good quality mobile phone charger and a 5V 2.1A USB outlet I have in the car and both work well.
