6.6 IWR6843AOPEVM Muxing Scheme
The IWR6843AOPEVM 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 6-2 and Table 6-3 .

Note
SOP0 is set high when switch is on the OFF position and low when the switch is the ON position. SOP
1 and 2 are set low when the switch is OFF and high when the switch is ON.
In mounted mode, the IWR6843AOPEVM is mounted on the MMWAVEICBOOST and the SOP mode
is set by the MMWAVEICBOOST.
6.7 Modular and MMWAVEICBOOST Mode
The IWR6843AOP can be used in modular mode or mounted on the MMWAVEICBOOST for debugging.
6.7.1 Modular Mode
When used in modular mode, the UART can either be routed to the SICP2015, which displays the data on the
mmWave visualizer, or to other devices connected to the USB interface. The UART data can also be routed to
the CC2640R2F, which transmits data to a wireless device through Bluetooth.
Figure 6-8 shows the setup for
SICP2015. Figure 6-9 shows the setup for CC2640R2F.
