README.TXT

This repository contains:

Original hardware design files for A13-OLinuXino and A13-OLinuXino-WIFI. These are made with Eagle 4.16r2. PDF exports are available also.

Both boards use same design files, but the A13-OLinuXino-WIFI comes with NAND memory and on-board MOD-WIFI-RTL8188ETV module.

Notice that it is possible that simultaneously purchased A13-OLinuXino and A13-OLinuXino-WIFI to be from different revisions.

Changes in revision G2 compared to previous revision G1:

- Changed C144 to 100pF

Changes in revision G1 compared to previous revision G:

- Added capacitor C144 1nF on DDR3-RST signal

Changes in revision F compared to previous revision E1:

- Changed the SD card package so that it is easier for repair and attachment
- Changed the package of the 32768 crystal to an SMT one (with 4 pins)

Board features:

- A13 Cortex A8 processor at 1GHz, 3D Mali400 GPU
