Step 45: Install 8-pin
header underneath at
‘P5’ and ‘P6’. Make
sure it’s straight
up-and-down!
Steps 45 & 46: 8 and 4 pin installation UNDERNEATH!
Step 45 & 46 - Eight and Four Pin Header Rails: Here’s another one of those tricky installs, where we want you to install the
parts on the underside of the circuit board. We’re going to install the pins that will connect the Discrete Brainboard to the
Mainboard. Since we’re sure you don’t want to install the brains in upside-down, just remember that they all are soldered in
from the bottom. Don’t worry, we’ll be reminding you to do this several times yet.
Take the two 8-pin headers and install them in positions ‘P5’ and ‘P6’, with the short end being soldered to the board. It’s quite
important to make sure that the pins are installed straight up-and-down, 90° degrees to the circuit board. The best way to do
this is by soldering only one pin on the header, then eyeball how it’s sitting. It’s easy to remelt the solder and tweak the
alignment if only one pin is soldered. When you’re happy with the alignment, go crazy and solder in the remaining 7 pins.
Use the same procedure on the 4-pin headers, and install them in positions ‘P7’ and ‘P8’. Same drill - solder only one pin and
make sure that the header is installed straight up-and-down.
Step 46: Install 4-pin
header underneath at
‘P7’ and ‘P8’. Make
sure it’s straight
up-and-down!
Final Installation. See? Pins Mounted UNDERNEATH!
A Tip for the Brave: Want an ideal way to mount your pins? Instead of the above steps, mount the pins into the sockets on the
main board. Drop the Discrete brainboard onto the pins, and solder a pin on each end of the pin strip. Pull the brainboard out
(with all 4 strips), and finish soldering. Now you’re guaranteed that each pin will mate with each socket!
Warning: You may melt the sockets if you take too long tack-soldering in the pins! That’s why you have to be brave doing it this
way! BUT, it’s also the best way to make sure everything aligns up nicely!
