Hardware

2.4.2 External 5-V Power Source Without USB Connection

If USB connection is not required, the 5V jumper in the isolation jumper block may be left populated (see

Figure 19). In this case, 3.3 V is derived through the dc-dc converter and, depending on the 3V3 jumper

setting in the isolation jumper block, can power the target device as well. If using external power source

for both 3.3 V and 5 V, consider recommendations for each.
