The following parts will be needed no matter if you solder the µC yourself
or use the core board. Some parts are optional. See comments.
In the Source column I put a
vendor where I bought parts.
This is not meant as advertisement, but as reference. Usually big vendors
like Mouser will have better prices, especially if you buy in large
amounts.
