ATxmega128A1U-AU development board. Onboard 128Mbit SDRAM. All IO leads out.

Warning: The BOM is automatically generated and may not match the actual situation. Please do not use the BOM table to place orders directly. Everything is subject to the PCB package and schematic values.

Please check out: Iris Cube->Series Microcontroller Development/Verification/Core Board Introduction

The R, C, L, X, and F prefixes of the component silk screen correspond to resistors, capacitors, inductors/magnetic beads, crystal oscillators, and fuses respectively; followed by the relevant values ​​of the components. There is not enough space to put the part number.

Connectivity:

• USB on PD, USB TYPE-C female socket;
• IIC on PC, 1.25T-4P female socket;
• JTAG, ATMEL standard 10-pin, 2.54mm 5p 2-pin row;
• PDI, 2.54mm 2p 2 pin rows;

Indicator light:

• Power Indicator
• PB6/JTAG-TCK dual-color indicator light

About the PB6 indicator light: Arduino legacy product. The Arduino Uno is connected to the ICSP clock. Since XMEGA does not have an ICSP, it is connected to the JTAG clock.

Remark

Update: I am back in 2077 and continue to improve the project.
