USB-to-Serial Communication Option
This option provides direct access to the SAMA5D3 MPU via a UART interface. It does
not require knowledge of the IP address and setting the IP address on the PC. In addi-
tion, it does not depend on a switch or PHY daughter board being attached to the
SAMA5D3 EDS board.
1. Get a USB-to-serial cable and install the PC driver if necessary. Examples are
the Microchip PICkit™ Serial Analyzer, the USB-to-TTL Serial Cable from Ada-
fruit (Product ID 954), and the FTDI TTL-232R-3V3 or TTL-232R-5V.
2. Connect the USB-to-serial cable to header J10 on the SAMA5D3 EDS board.
a) If using the Adafruit USB-to-Serial Cable (Product ID 954), connect white to
J10 pin 2, green to pin 3, and black to pin 6. Red is not used. See

J10
b) If using a TTL-232R cable from FTDI, the 6-pin SIL connector on the cable
plugs directly into J10 on the board, with green at J10 pin 1 and black at J10
pin 6. See
