Atmel AVR ATxmega128A1 microcontroller module with USB UART, RS485, micro-sd-card, voltage regulator.
CrumbX128A1 AVR Xmega Module
Description
CrumbX128A1 V1.0 is a versatile and very compact/small (just 60x30mm size!) microcontroller module with the ATxmega128A1 microcontroller, 3.3V LDO voltage regulator, CP2102 USB UART converter, RS485 transceiver and a micro-sd-card header/slot. All microcontroller signals are available on pin headers. A selectable XTAL crystal is included.
The module is shipped without preassembled pin headers, since everybody has different preferences or requirements.
You can find further information in the Infosheet.
