* Atmel AVR XMEGA AU, A, C, or D 44-pin microcontroller
ATxmega32a4u, ATxmega128a4u, ATxmega16C4, ATxmega32D4, ATxmega128D4
AU (A4U) and C variants support USB device mode
* Onboard 3.3V, 500mA LDO regulator
up to 6V DC input
low quiescent current (120uA typical, 220uA max.)
low dropout (210mV typical, 350mV max. @ 500mA)
0.5% output tolerance typical
Over-current and over-temperature protection
* Simple power source switching
2 schottky diodes (Vbus and Vin)
Vbus can be disconnected (solder jumper)
Vin schottky can be shorted (solder jumper) to eliminate voltage drop (battery use)
Either Vin or Vbus can be routed through a resistor divider (/2) to pin B3 (ADC)
* PTC resettable fuse (500mA)
* DFU bootloader preinstalled (FLIP for Windows or dfu-programmer for Linux)(NOT on A or D variants)
* PDI/SPI header (PDI by default)
As a PDI header, it is used to program the AVR with an external programmer
Header can be converted to a SPI (master or slave) header
Can mount the MT-SD MicroSD card slot directly to this header
* 16MHz crystal for main clock
* 32.768KHz crystal for real-time counter
* Green Status LED (can be disconnected)
* Reset button
* Bootloader activation jumper
* Mini USB connector
* USB pins routed to header pins (for panel-mount USB connector)
* Powered by USB or external power source (up to 6V) on Vin
* Ferrite bead on analog supply
* 19 solder jumpers for configuration flexibility
* All PORT pins routed to headers (except R0)
* 2 main headers are on 0.1” spacing (breadboard/perfboard mounting)
* Two 3mm mounting holes (~5mm pad)
* High-quality PCB with gold-plated finish
* Measures approx. 2.1” x 0.9” (52mm x 33mm) and 0.062” (1.6mm) thick.

USB DFU Bootloader
MT-DB-X4_DFU_Bootloaders_104.zip Revision 104
MT-DB-X4_DFU_Bootloaders_104.zip contains the USB DFU bootloader that comes pre-installed. It is compatible with FLIP for Windows and dfu-programmer for Linux. More information can be found at http://www.atmel.com/images/doc8429.pdf and the User Guide
MT-DB-X4_Blink.zip contains the blink demo hex file that comes pre-installed, as well as the source code. It simply blinks the LED at 1Hz using the 16MHz crystal as the clock source.
FLIP is a graphical utility for Windows used to load firmware into the XMEGA. FLIP supplies the USB DFU bootloader driver. Download FLIP 3.4.7 or higher from http://www.atmel.com/tools/flip.aspx and install. Older versions may not support the latest XMEGA variants (AU or C). Once FLIP is installed, the USB DFU drivers can be loaded. Install the boot jumper and power the board (or press reset). This will start the DFU bootloader. Windows will then prompt you for the driver, which is located in the Program Files/Atmel/Flip 3.4.7/usb directory. Point the installer to that directory and install.
