1. Power supply
Ready for XMEGA board can be powered in two ways: via USB connection, or using external power sources such as adapters and
laboratory power supplies. USB connection can provide up to 500mA of current which is more than enough for every on-board module
and for operation of the microcontroller. If you decide to use external power supply, you can choose between AC/DC adapter connector
or power screw terminals. Voltage values must be within 7-23V AC or 9-32V DC ranges. Power LED (GREEN) will indicate the presence
of power supply. Use only one of suggested methods for powering the board.

The microcontroller can be programmed in three ways:

Page 12
Page 13
Programming with mikroBootloader
You can program the microcontroller with bootloader which is
preprogrammed into the device by default. To transfer .hex le
fromaPC to MCUyou need bootloadersoftware(mikroBootloader
USB HID) which can be downloaded from:
After software is downloaded, unrar it to a desired location, and
start mikroBootloader USB HID software.

note
Figure 3-2: mikroBootloader window
mikroBootloader software
01 When you start mikroBootloader software, a window
shown on Figure 3-2 should appear.
Before starting mikroBootloader software, connect Ready for
XMEGA with a PC using USB cable provided with the package
This version of mikroBootloader is specialized
for ATxmega128A1 chip.

Ready for XMEGA board contains JTAG connector pads so you can program the board and debug your code using external programer/
debugger. Before connecting the programmer you have to solder the provided IDC10 2x5 male header onto the board’s JTAG connector
pads. If bootloader program is accidentally erased, you can upload it again via AVR JTAG or PDI programmer. Ready for XMEGA Bootloader
Firmware.hex can be found under Firmware folder (see page 12).

The board is also equipped with PDI connector
pads, which allow you to program the microcontroller
using external serial PDI programmer. Before attaching the
programming connector, you have to solder the provided 2x3 male
header to the board’s PDI connector pads.

USB-UART schematics
Fast on-board FTDI® chip allows you to communicate
with a PC or other UART devices using USB-UART connection.
USB-B connector (CN3) is used for connecting the USB cable. RX
(receive) and TX (transmit) LEDs will indicate communication status.
Before conecting the board with the PC, make sure to have the
appropriate FTDI drivers installed on your operating system.
Drivers can be found at following URL: Figure 4-1:
