Before you wire
4 cautions- USB host/OTG mode requires populating 0 Ω resistors R25/R29, which permanently repurpose PB0/PB1 and conflict with J1 pins 3–4 (SPMU296).
- Header pins are heavily alternate-function muxed; consult SPMU296 tables 2-3 to 2-6 before wiring.
- A board that will not power on may be latched in Hibernate — wake via SW2 (PF0/WAKE).
- J3/J4 carry board-specific extended functions; MSP430-style BoosterPacks designed only for J1/J2 can miswire on them.

This board has official references linked, but its in-app connector map still needs a source-backed import.

Why it matters
- Onboard ICDI enumerates as debugger plus virtual COM port over one USB cable.
- Motion-control PWM (two modules, 16 outputs) supports 3-phase inverter designs directly.
- BoosterPack XL header is backward compatible with MSP430 LaunchPad BoosterPacks.
- Native USB 2.0 host/device/OTG on the target MCU itself.
