Overview
Introduction
The MTX1S 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, RS232 or RS485, 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.
