2.8 AWR1843AOPEVM Muxing Scheme
The AWR1843AOPEVM UART RX/TX can be routed to the Samtec 60-pin connector, USB to UART
(SICP2105), and bluetooth (BT) device (CC2640R2F), as detailed in
Table 2-8 .

Note
SOP0 is pulled high when switch is on the OFF position and low when the switch is the ON position.
SOP 1 and 2 are pulled low when the switch is OFF and high when the switch is ON.
In MMWAVEICBOOST mode, the AWR1843AOPEVM is mounted on the MMWAVEICBOOST and the
SOP mode is set by the MMWAVEICBOOST.
2.9 Modular, MMWAVEICBOOST, and DCA1000 Mode
The AWR1843AOP can be used in modular mode or mounted on the DCA1000 or MMWAVEICBOOST for
debugging.
Modular mode is primarily used when running application code or the SDK mmWave Demo. In this mode the
user will have access to the UART and Logger ports via the USB connector (J1) as well as the on-board CAN
trancievers (J8, J10) and the Bluetooth/JTAG header (J7).
Additional debug interfaces (DMM, LVDS, SPI) and tools (mmWaveStudio) can be accessed by connecting to
the MMWAVEICBOOST on the J2 connector. For more details about the MMWAVEICBOOST features and uses,
refer to the
MMWAVEICBOOST User's Guide .
Raw data capture over the LVDS interface with mmWaveStudio can be accomplished by directly connecting the
EVM to the DCA1000 EVM on the J11 connector. For more details about the DCA1000 EVM and its features,
refer to the
DCA1000 EVM User's Guide .
