This is a logic board part number 820-1414-A for Apple iPod Classic 1st Generation M8541.
This logic board has been fully tested and works great. It comes with the scroll wheel.
The headphone jack may have some chipping (common with this model), but everything is fully functional. You can look at the photos for an approximate representation of the condition, but please be aware it is a stock photo so your actual serial number and condition may vary slightly from the photos.
