.
• The EVM board can be powered by RF scavenged energy, battery, FET emulator tool, or USB power.
When powered through the USB connection or an MSP-FET emulation tool, switch S6 must be set to
"Supply". If the EVM is powered by scavenged RF energy or a battery, switch S6 must be set to
"Battery".
• Level translators are used on I
2
C, SPI, and FET emulator interfaces.
• The power (green) LED should turns on only when the board is powered by a USB connection.
• Jumper SV7 is needed to bypass the internal battery switch and provide power directly to the core.
This jumper should be populated for most use cases.
• When the EVM is powered by the USB connection, the Alarm LED briefly flashes at power-up or stays
illuminated if there is an interrupt from the RF430FRL152H. It is normal for the Alarm LED to stay lit
during MSP-FET tool programming.
