LEDS1 MAIN BOARD PARTS LIST
The main board is the larger of the two. Sort and “check off” the components
in the boxes provided. We do our best to pack all our kits correctly but it is
possible that a mistake has occurred and we missed a part. Please note that
physical descriptions of parts are for those currently being shipped. Some-
times the parts in your kit may have a different appearance but still have the
same values.
