POWER SUPPLY
The EVB power can be provided by USB hosts or an external 5V supply which is then converted by
LDOs to create the 3.3V and 1.8V needed for the onboard circuits. There is no switch needed for
selecting a particular supply. Instead, diodes are installed to provide reverse current protection for
each individual supply. Jumpers CN11 may be used to measure the current consumption of the
module as described in Section 9. A block diagram of the power supply connections is shown below.

3.1 USB power supply
In the default configuration, the EVB is connected to a PC through at least one of the two mini-USB
ports CN13 and CN14. These connections provide the USB-UART serial interfaces and serve as the
power sources for the EVB. The mini-USB connector locations are as shown below in Figure 6.
