Eight encoders with switch functions connect to the SRIO chain on the le MEC board below. The PCB also holds Matias switches.
Note that two sets are required for a SEQv4+ build.
The encoders are directly connected through the headers to DIN pins in the stacked PCB. The switches are connected to the matrix through diodes.

Please find the current BOM on http://midiphy.com. The table below is depreciated and will not be updated.
Note: two sets are required per SEQv4+!
v1.0: first release.
Start with the eight encoders and diodes. Important to note:
Once the diodes and encoders are okay, line up the headers, using a le MEC board and optionally some of the mounting points. Once you are happy, solder the three 1*10 male pin headers on the lower PCB, and only then fix the through-board female headers on the upper PCB.
We need to first decide how the case will come together, but it is wise to now align the mounting washers. Lastly the Matias switches are mounted in the Plate PCB, and are soldered below.
So it could be that the DIN functions of buttons and encoders are tested prior to installing the switches.
