+configs/pic32mx README
+=====================
+
+This README file discusses the port of NuttX to the PIC32MX board from
+PCB Logic Design Co. This board features the MicroChip PIC32MX460F512L.
+The board is a very simple -- little more than a carrier for the PIC32
+MCU plus voltage regulation, debug interface, and an OTG connector.
