Depending on how you plan to use the adapter, simply follow the normal rule-of-thumb for
assembling electronic projects: install the parts by their height starting with the shortest and
graduating to the tallest parts.
Determine how the snap-in will be used first, then select the parts necessary for your
application.
Sort the parts into shortest to tallest order, then install them.
3.3v regulator – 3 types are available; be sure to mount your choice in the proper position,
matching the outlines on the PCB:
o The UA78M33 regulator's position is marked with small dots
o The LM1117T regulator's position is marked with small triangles
o The LM78L33 regulator is near the TOP of the PCB; be sure to
orient the
Setting the ESP Circuit Connection (Does not apply if using an XBee)
Depending on which version of the ESP firmware you use, you will need to connect two circuit pads
on the Snap-In with a blob of solder. The ESP module will send data to your controller unless you do
this step properly. You may apply the blob of solder on either the top or bottom side of the PCB.
If you use Bill Porter's original ESPixelStick Firmware for the ESP module,
connect the two pads marked 'TX'. This sends the data to the controller via
the ESP's TX pin. (Bill Porter was instrumental in adding both Renard and
DMX serial capability to Shelby Merrick's ESPixelStick firmware. At the time
of this writing, he is working on a new version.)
If you use Shelby Merrick's newest ESPixelStick firmware, connect the two
pads marked '2'. This sends the data to the controller via the ESP's GPIO-2
pin. (Shelby Merrick's original version of the firmware did not include the
Renard or DMX serial options; Bill Porter added them. In Shelby's version 2
update, the firmware still used the GPIO-2 output port.)
An option to use GPIO-0 is provided although no firmware currently uses this pin for output
and it's reserved for future use; do not solder across the '0' pins.
