2.2.3 Step 3 — Attach Module to Prototyping Board
Turn the RCM4400W module so that the mounting holes line up with the corresponding
holes on the Prototyping Board. Insert the metal standoffs as shown in Figure 4, secure
them from the bottom using the 4-40 × 3/16 screws and washers, then insert the module’s
header J1 on the bottom side into socket RCM1 on the Prototyping Board.
Press the module’s pins gently into the Prototyping Board socket—press down in the area
above the header pins. For additional integrity, you may secure the RCM4400W to the
standoffs from the top using the remaining three screws and washers.

NOTE: It is important that you line up the pins on header J1 of the module exactly with
socket RCM1 on the Prototyping Board. The header pins may become bent or damaged
if the pin alignment is offset, and the module will not work. Permanent electrical dam-
age to the module may also result if a misaligned module is powered up.
