2.7 Connectors
2.7.1 Power Connector (J5)
The EVM can be powered by the 5-V power jack (2.5-A current limit), shown in Figure 2-13 . When the power is
provided, the NRST and 5-V LEDs should glow, indicating that the board is powered on.
The J5 connector is intended to be used when using the EVM with the DCA1000 or in stand alone (modular)
mode. When using the EVM with the MMWAVEICBOOST, the 5-V supply is provided by the MMWAVEICBOOST
board, so power over the J5 connector is not required.
When the breakaway section is removed, power should come from the USB connector (J1). See more details
about this connector in
Section 2.7.2 .
Note
After the 5-V power supply is provided to the EVM, TI recommends pressing the NRST switch (SW2)
one time to ensure a reliable boot-up state.
