SC18IM704-EVB evaluation board
The power for the SC18IM704-EVB evaluation board is provided via the micro-B USB
(J2), or via the I
2
C interface header (JP2).
The SC18IM704-EVB evaluation board 9-pin RS-232 port (J1) is intended to be the
main UART interface to the host’s UART, but UART TX and RX CMOS level signals are
available on JP5. When JP5 is used to interface to the host’s UART then the jumper on
JP4 should be removed to remove power from the RS-232 line driver.
