Part Lists

Required Parts

These are the parts required to fully populate the META42 board. Some of these parts are optional. (Click the link for more info.)

I don't give part numbers for resistors because resistors are more or less generic. I recommend 1% metal film types; pick any type you like. (See this for more details.) See the schematic and the parts selection advice page for recommended resistor values.

Some components are marked "Alt.". These are alternatives for the immediately preceding component.

Bolded part numbers are the ones that I've personally used, and liked. The un-bolded numbers are parts I picked based on their specs, but haven't yet tried.

Optional Parts

Here are some parts that you may need, or that are "preference" things: I can't call them required, since some may disagree.
