2.2 Hardware Connections
There are three steps to setting up the Prototyping Board:
1. Attach the RCM3900 module to the Prototyping Board.
2. Connect the serial programming cable between the RCM3900 and the workstation PC.
3. Connect the power supply to the Prototyping Board.
2.2.1 Step 1 — Attach Module to Prototyping Board
Turn the RCM3900 module so that the Ethernet jack is facing the direction shown in
Figure 2 below. Align the pins from headers J61 and J62 on the bottom side of the module
into header sockets JA and JB on the Prototyping Board. The microSD™ Card does not
have to be inserted into connector J2 on the RCM3900 at this time—there is a protective
spacer insert that you simply pull out before inserting a microSD™ Card for the first time.
Press the module’s pins firmly into the Prototyping Board header sockets—press down in
the area above the header pins using your thumbs or fingers over the header pins as shown
in Figure 2. Do not press down on the microSD™ Card connector (J2) even if the
microSD™ Card is installed, but rather press down on the circuit board along the edge by
the connector. Also, do not press down on the middle of the module to avoid flexing the
module, which could damage the module or components on the module.
Should you need to remove the module, grasp it with your fingers along the sides by the
connectors and gently work the module up to pull the pins away from the sockets where
they are installed. Do not remove the module by grasping it at the top and bottom.

Do not press down
here or on
NOTE: It is important that you line up the pins on headers J61 and J62 of the RCM3900
RCM3900
module exactly with the corresponding pins of header sockets JA and JB on the Proto-
typing Board. The header pins may become bent or damaged if the pin alignment is off-
set, and the module will not work. Permanent electrical damage to the module may also
result if a misaligned module is powered up.

CAUTION: You will sense a soft click
once you insert the microSD™ Card
completely. To remove it, gently press
the card towards the middle of the
RCM3900 — you will sense a soft click
and the card will be ready to be removed.
Do not attempt to pull the card from the
socket before pressing it in — otherwise
the ejection mechanism will get dam-
aged. The ejection mechanism is spring-
loaded, and will partially eject the card
when used correctly.
