NOTE: Due to manufacturing changes required to meet new EU legislation, P3 is no longer available in kit form
These notes are provided for reference of existing kit owners.

These are the construction notes updated for board revision 1.6

NB. Assembly from a kit is not recommended for beginners
It's not my intention to give a tutorial on how to populate a PCB here, there are plenty of pages on the web offering advice on the subject. Any specific gotchas will be pointed out on the page for each board.

The P3 PCBs

The P3 Sequencer is constructed from a set of 9 PCBs.
As well as the PCB/CPU kit, you will need to buy all the parts on the bill of materials, and provide a suitable enclosure if you don't opt for the high-quality production case.
