4. MCU Daughtercard information
In order to use the EVB, an MCU daughtercard must be fitted as described in the following section.
Before fitting or removing a daughtercard, ensure the EVB is powered OFF
4.1. Fitting a daughtercard
Gently place the daughtercard on the EVB connectors ensuring the correct orientation as shown in the
following figure. The connectors are polarized so the daughtercard will only fit in one orientation (with
the jumpers at the bottom of the daughtercard). Once the connectors have been located correctly, firmly
push down all four corners of the daughter card simultaneously in order to ensure the connectors are
mated. (The following picture also shows the default jumper positions for the 256BGA daughtercard)

4.2. Removing a daughtercard
In order to prevent damage to the daughtercard connectors, it is important to remove the daughtercard
correctly. Carefully lift either the top or bottom edge of the daughtercard and it should easily lift off as
shown in the following figure (viewed from the left side of the EVB).

CAUTION
Do not attempt to lift the left or right edge of the daughtercard as this will
result in connector damage.
