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. Latest hardware revision: revision H Major changes in revision H compared to previous revision G2: - Q1 value changed from HC49/S1 to Q24MHz/20pF/20ppm/2P/HC-49SM(SMD); - Q2 changed from HC49/S1 to Q12MHz/20pF/20ppm/2P/HC-49SM(SMD); - Q3 value and package changed from 32768Hz/6pF to Q32.768kHz/12.5pF/20ppm/4P/SMD8038; - RM16 renamed to RM11; - U10 and U15 changed from SY8008C(AA)C to SY8009AAAC(SOT23-5); - U16 changed from SY7208(SOT23-6) to MT3608(SOT23-6); - PWR-JACK value changed from YDJ-1136 to PWRJ-2mm(YDJ-1134); - Optimized R84 from 100k/1% to 4.99k/1% and R86 from 22k/1% to 1.1k/1% ; - Optimized C134 from 47pF to 33pF ; - Optimized C114 from 22pF to 33pF ; - Optimized L12 from FB0805/600R/200mA(201209-601) to FB0805/600R/2A ; - Optimized L1 from CL470nH/0805/1.76R/250mA to FB0805/600R/2A; - Optimized R43, R98, and R99 from 51R to 22R; - GPIO-2 and LCD_CON were changed from ML40 to BH40S. 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 - 512 MB RAM (2 x 256Mbit x 8) - 4GB NAND Flash (for A13-OLinuXino-WIFI) - 6-16VDC input power supply, noise immune design - 3 + 1 USB hosts, 3 available for users, 1 leads to onboard pinout or to WIFI module (for A13-OLinuXino-WIFI) - 1 USB OTG which can power the board - SD-card connector for booting optional Linux images - VGA video output - Battery option and connector - LCD signals available on connector so you still can use LCD if you disable VGA/HDMI - Audio output - Microphone input - 4 Mount holes - RTC PCF8563 on board for real time clock and alarms - 5 Keys on board for android navigation - UEXT connector for attaching expansion boards (sensors, relays, etc) - GPIO connector with 68/74 pins and these signals: - 17 for adding NAND flash; - 22 for connecting LCDs; - 20+4 including 8 GPIOs which can be input, output, interrupt sources; - 3x I2C; - 2x UARTs; - SDIO2 for connecting SDcards and modules; - 5 system pins: +5V, +3.3V, GND, RESET, NMI - Dimensions: (120x120)mm ~ (4.7x4.7)''
