DESCRIPTION

PROJECT

R

J1 and J2 provide compatability with

Booster Packs designed for MSP430 Launchpad

Used for VBUS detection when

configured as a self-powered USB Device

J3 and J4 sit 100 mils inside J1 and  J2 to provide 

extended functions specific to this board.

See the board user manual for complete table of pin mux functions
