Connector Type
X17: 2.54 mm, 2 x 5 pin header
4.10.3
COM Port 2
COM port 2 signals are connected to pins 41- 44 of the feature connector. These signals are shared with M.2 connector, via a multiplexer. The
conga-SEVAL routes COM port 2 signals to the M.2 connector if an M.2 card is detected.
COM port 2 supports I/O voltage levels of 1.8 V. See section 5.3 “Feature Connector” for the pinout description.
4.10.4
COM Port 3
COM port 3 signals (TX and RX) are connected directly to pins 9 and 11 of the feature connector. These pins support I/O voltage levels of 1.8 V.
See section 5.3 “Feature Connector” for the pinout description.

FAN
The conga-SEVAL provides a 4-pin fan connector (X42). The fan’s PWM control and tachometer pins are multiplexed with GPIO5 and GPIO6
respectivitely.
Use jumper X43 to set the supply voltage of the attached cooling fan to 5 V or 12 V.
