6.4 Connectors
Higher current support: When using the EVM with the external power adaptor, the 5-V supply is provided by
the external power adaptor. For most of the use-cases this external power supply option is not used, power is
derived from the USB interface.
Note
After the 5-V power supply is provided to the EVM, TI recommends pressing the NRST switch one
time to ensure a reliable boot-up state.
Note
All digital IO pins of the device (except NRESET) are non-failsafe; hence, care needs to be taken that
they are not driven externally without the VIO supply being present to the device.
6.5 USB Connector
The USB connector provides a 5-V supply input to power the device; additionally the PC interface is brought out
on this connector:
• UART for flashing the onboard serial flash, downloading FW through Radar Studio, and getting application
data sent through the UART

6.6 DCA1000 HD Connector
The 60-pin HD connector shown in
provides the high-speed data and controls signals (SPI, UART,
I2C, NRST, NERROR, and SOPs) to the DCA1000.
