Atmel AVR ATxmega32A4U microcontroller module with USB UART, micro-sd-card, voltage regulator.

CrumbX32A4 AVR Xmega Module

Description

Crumb32A4 V1.0 is a versatile and very compact/small (just 56x18mm size!) microcontroller module with the ATxmega32A4 microcontroller, 3.3V LDO voltage regulator, CP2102 USB UART converter 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.
