 ===== Assembly =====
-Decide on the layout. Only four encoders are supported. ENSW1 and ENSW4 are always available; EN2/ENSW2 and EN3/ENSW3 share pins. The switch for ENSW2/ENSW3 is also shared. This way one can choose whether to have switched encoders or encoders illuminated with WS2812B LEDs.
+If using touch sensors, install the SMT parts first. Capacitor pads have rounded corners and there is a silkscreen line along the longer edge to help orient the parts. See above for how to connect TS parts (normally a wire link).
-If illuminated encoders are desired, install these and the associated capacitors first.
+The WS2812 LEDs and associated caps should come next, followed by the SMT shift registers and resistor networks. See above for notes on the RNs.
-Next diodes and resistors/links. Align the diode band with the silkscreen legend. Next the two electrolytic caps.
+Here it is a good idea to test the LED functions before overlaying the encoders.
+The encoders can then be installed over the LEDs. They need to be raised above the LED (e.g. using a spacer piece of 2mm) so the shaft turns freely, and the mounting legs should be straightened for a secure connection.
+OLED displays should go in last. As they mount over the touch sensors, it would be smart to test the touch sensor operation before they are placed.
+Example usage:

-OLEDs could be socketed using a right-angle pin header. This means a corresponding female header would need to replace the standard 7-pin one common to these displays.
-Headers, switches and encoders come last. Note the flat part of the switch, which must align with the DT6 switch body. Illuminated encoders should be raised up around 2mm to fit over the LED and still turn freely.

 ==== Interconnection to Core ====
-Headers are mentioned above. DIN/DOUT connect to DINX4/DOUTX4 or a DIOMATRIX. J10B to J10B
+  * J1 to J4B (I2C)
+  * J3 to J89 (SRIO)
+  * J5/J6 to J15 or equivalent. The ribbon cable should have two IDCs on the ELO end, one for J5 and one for J6.
+  * J7 +5V as noted.
