+There's not much here:
+
+EXT1 - P3 0:7 are used for LEDs.
+
+UEXT pin 3/4 -TXD2/RXD2- is UART2.
+
+The board I have has the revision '-' of LPC2378 even though I got the board
+more than 2 years after the chip revision was released :-( .
+I can't get Nuttx to work if I fully enabled the MAM.
+
+I used FTDI ft232 usb-serial with nsh piping as seen on the screenshot.
