Order components

To buy your parts you need a electronic component distributor or you can buy from many different sources.
In this guide we will use Digikey.

At first you need the Digikey part number of all parts of your options AND the bare minimum shield. You can find it by looking into the BOM.

Now go to https://www.digikey.com/ and search for this part number and add it to your cart. If part is out of stock you can find parameters in data sheet and find substitute. Digikey search system will help you to do it.

Don't forget to buy a automotive mini fuse to put into the fuse holder. You can find suitable fuses here or from many different sources.

Hint: What fuse should I pick?
