MT-X1S Manual
Overview
Overview
Introduction
The MT-X1S is a flexible USB development board for the Atmel ATxmega128a1u
microcontroller. Optionally available is a MicroSD card slot, 32KB SPI SRAM, audio amplifier,
lowside / relay driver, temperature sensor, RS-232 or RS-485, 4 LEDs, and an onboard 1.25V
precision reference for the ADC. The XMEGA can be programmed over USB using the optional
onboard AVRISP mkII compatible PDI programmer. The XMEGA can communicate with a computer
using the optional onboard USB to serial bridge (up to 2Mbps). The Atmel AT90USB162 USB AVR,
which provides these features, will automatically sleep when USB is disconnected. Alternatively, the
XMEGA can be connected directly to the USB connector. The board can be powered via USB or an
external header. Voltage is regulated by a 3.3V, 1A LDO regulator. There are several clock options
available onboard, including a 32.768KHz crystal, an external clock, an external HC49 crystal landing,
and several internal clock options. Most XMEGA pins are routed to headers. The included peripheral
devices are connected to the XMEGA via solder jumpers, which allows use of the pins if the device is
not used. A demo program is preinstalled on the XMEGA demonstrating use of each peripheral
device, as well as demonstrating sleep mode.

Revision B Changes
Revision B Changes
Revision B includes the following changes:
1) Add jumpers J33 and J34 to allow routing of the USB data lines to either the XMEGA or the AVR.
Jumpers J10 and J11 were changed to 3-pad to support this. The Serial RAM cannot be used when
the XMEGA is connected to USB.
2) Add PTC fuse to USB Vbus
3) Change both crystals and buttons to SMT
4) Change 32.768KHz crystal load capacitors
5) Support a variant of the board without the onboard PDI programmer / serial bridge by adding J35
through J38:
* J35 connects the STS_LED to TX (XMEGA F2)
* J36 connects the PROG button to XCK (XMEGA F1)
* J37 disconnects the debouncing capacitor of the Reset button for use with the XMEGA
* J38 connects Reset button to XMEGA PDI_CLK (also reset)

* Direction indicates which pads are soldered when the board is
viewed with the USB connector to the left. Disconnected means no
solder connection from the center pad to either of the outer pads.
If you have the programmer installed, you may switch the USB data connection between the
programmer (AT90USB162) and the XMEGA. See the table above for jumper settings. Note that
because the AT90USB162 is mounted, the XMEGA cannot control the STS LED, otherwise contention
would occur. When the AT90USB162 detects that USB is disconnected, it will turn off both the STS
and PWR LEDs and enter sleep. The RESET button should not be connected to the XMEGA. The
AT90USB162 will reset the XMEGA after the button is pressed. Because the serial connection
between the two chips is unused in this configuration, J19 should be disconnected (and optionally
J18). Additionally, be sure that the Serial Mode is set to Asynchronous and the USB Ready Signal is
Disabled in the AT90USB162 configuration (see the Configuration chapter). Finally, the XMEGA
BOOTRST fuse bit must be changed so that the bootloader is run after reset. This can be done with
the onboard programmer prior to changing the jumpers.
The XMEGA demo program is installed on all board variants, even those without the optional
onboard peripheral devices. In these cases, most of the functionality will be useless except for the
LED demo (the 4 LEDs are always installed). Additionally, if the optional onboard PDI programmer /
serial bridge is not installed, communications must be made by connecting a USB-serial converter to
pins F2 (XMEGA TX) and F3 (XMEGA RX) at 1000000 baud (8N1).
See the XMEGA USB DFU Bootloader chapter for details on the XMEGA bootloader.

J33
Jumpers J33 and J34 allow routing of the USB data lines to either the XMEGA or the
A90USB162. Jumpers J10 and J11 were changed to 3-pad to support this. The Serial
RAM cannot be used when the XMEGA is connected to USB. See Board Variants
section above.

J35 J35 connects the STS_LED to TX (XMEGA F2) . This allows the XMEGA to control the
STS LED when the AT90USB162 in not installed. See Board Variants section above.
J36 J36 connects the PROG button to XCK (XMEGA F1) . This enables bootloader entry selection for the DFU bootloader on the XMEGA when the AT90USB162 in not installed.
See Board Variants section above.
J37 The XMEGA reset line is also the PDI_CLK line used for programming/debugging. It
cannot have a capacitor installed. J37 disconnects the debouncing capacitor of the Reset
button for use with the XMEGA . See Board Variants section above.
J38 J38 connects Reset button to XMEGA PDI_CLK (also reset). This allows the XMEGA to
be reset when the AT90USB162 in not installed. See Board Variants section above.
Headers / Pin Descriptions
Pin Description
External Power Header Under the default configuration, 5V should be supplied to this pin. Lower
voltages may be used down to around 4V (or lower if using less current).
Voltages greater than 5.5V require J2 to be disconnected. Disconnecting J2
will disable the 5V output pin and inductive kickback protection of the relay
driver. But it will then allow voltages up to ~7.5V. This header is reverse
polarity / reverse current protected using a schottky diode.
3.3V output headers (x4) There are four 2-pin power output headers next to each port header group. The
header next to the analog ports (ports A and B) comes from the analog 3.3V rail.
Note that if these headers are installed, there will not be enough room to plug in
IDC connectors next to each other.
Relay Header 3.3V This can be used for the positive 3.3V side of a relay or other device.
