Figure 1. EVM
LEDs— Display status of POWERGOOD, RESET_OUT, LDORTC and power supply of MSP430
USB— Connection to PC to enable communication through the GUI
MSP430— Microcontroller used to convert USB data to I

C format
SMPSxx— Monitor point for SMPS outputs
J46— Monitor point for LDO outputs
J31— Jumper used to select VIO voltage. J31 requires a jumper installed (only one), and by default is in
position 10, 1V8.
J27— Jumper that provides access to the GPIOs
J20— VSYS power supply input. J20 is the same connector as SMPS123, and must not be confused to
prevent applying VSYS to SMSP123-output.
