2.4 External 3.3-V and 5-V Source

To use external 3.3-V and 5-V supplies to power the EVM, connect the 3.3-V, 5-V, and GND pins of the supply to the 3.3V, 5V, and GND pins of the external power header (J11) or the BoosterPack headers (J1 for 3.3V and J3 for 5V). Disconnect the onboard 3.3-V LDO (U5) from the 3.3-V power rail by removing the jumper on JP8 to prevent back-powering the LDO. Figure 2 shows the location for JP8.
