17:
Solder the 26 pin boxed header in the front of the primitive side.
18:
Solder the 1µF
(C2)
capacitor with the cathode facing away from the terminal in the front of the
primitive side. Cut the wires as short as possible after soldering.
19:
Solder the 100µF
(C1)
capacitor with the cathode facing away from the terminal in the front of
the primitive side. Cut the wires as short as possible after soldering. (220µF shown in image)
At this point it is important to check all connections on the address front side and the primitive back
side . Make sure there are no shorts or unconnected pins. Once the 2 boards are fully soldered
together, they are not going to come apart again without some serious work. With this check, the
TLC59213 on the bottom of the primitive side is the highest risk of having a mistake.
Once you are happy with all the connections, you can move to the next steps.
20:
Use the spacers, 12mm screws and one nut to mount the assembly to the primitive side. The 5
pin header should go from the address side and through the bottom of the primitive side. hand tight
is tight enough for the nuts in this stage of the build.
The set of 2 screw on the pogo pin side of the board should have no nuts. The M3 nuts will obstruct
the template later.
