7.3.1 Connecting an AC Adapter
An ac adapter can be connected to barrel jack J2 on the MMB0. J2 is located next to the USB connector.
The adapter must output 6V-7V dc. The connector must be sleeve-negative, tip-positive. It should have a
current rating of at least 2A.
Jumper J12 on the MMB0 connects a wall-mounted power supply to the board. To use the wall-mount
supply, J12 must be shorted. Figure 4 illustrates how to connect an ac adapter to the MMB0.

7.3.2 Connecting a Laboratory Power Supply
A laboratory power supply can be connected through terminal block J14 on the MMB0, as shown in
Figure 5.
To use a unipolar lab power supply configuration:
• Disconnect J12 on the MMB0.
• Connect a +5V dc supply to the +5VD terminal on J14.
• Connect ground of the dc supply to the GND terminal on J14.
It is not necessary to connect a +5V dc supply voltage to the +5VA terminal on J14 if the +5V/+5VA
position on J13 is shorted.
