A13-OLinuXino preliminary schematic is complete, here is what we got:
- A13 Cortex A8 processor running at 1GHz
- MALI 400 GPU, 1080p codec
- 512 MB of RAM
- 3+1 HS USB hosts (one reserved for WIFI module on board)
- USB OTG (can power the board)
- Audio input
- Headphone output
- VGA connector
- (optional 4GB NAND flash on board)
- micro SDcard
- 6-16VDC power supply input
- (optional LiPo battery power supply block, allow board to run hours on LiPo 3.7V battery)
- (optional RTL8188CU WIFI module on board)
- 5 buttons
- Real Time Clock module with PCF8563
- LCD expansion port, if no connected to LCD provide 30 GPIOs
- UEXT connector with SPI, I2C, UART for attaching additional UEXT modules
- GPIO connector with 40 GPIOs
- console UART header for USB-SERIAL-CABLE console debug
The readable PDF version of the schematic is push on GitHub. CAD files will not be uploaded until we complete and debug the design.
We try to put this in 120×90 mm board size and this picture show preliminary attempt to put the connectors on correct locations.
when we released iMX233 everyone was comparing this ARM9 board with Raspberry Pi or Beagle Bone, commenting how small memory it have and runs on only 454Mhz.
Now if we have to do same comparison and if we trust what is written here: http://lists.phcomp.co.uk/pipermail/arm-netbook/2012-June/004194.html i.e. that Cortex-A8 + NEON coprocessor at 500Mhz runs applications x4 times faster than ARM1176 at 720Mhz we have to say thay A13-OLinuXino will have x2 times more memory than RaspberryPi and will run code x8 times faster.
If we compare A13-OLinuXino with BeagleBone it will have x4 times more memory and will run code about x1.5 times faster.
EDIT: 13.06.2012 PCB layout changed to 130×90 mm to fit all connectors and buttons:
