USB Interface

The USB Interface uses the standard USB connector on the MCB2140 board, for the full speed USB 2.0 peripheral of the LPC2140 device.

MCB2140 Board USB

By default, the MCB2140 Board is configured as a USB-powered device. Remove the 0 Ohm resistor (R37) to use the VIN connector P14 as an external power supply connection.

You may disconnect the USB interface using the configuration jumpers D- (J12) and D+ (J14).

The configuration jumper VR (J15) connects 5V supply from the USB connector to the VBus pin (P0.23).  The USB Power LED indicates the presence of USB BUS power to the device.
