The Olimex A13-OLinuXino-Micro is a shrunk down, cheaper version of the A13-OLinuXino. The differences against the A13-OLinuXino are that it has half the ram, a single USB Host port, only u-boot and reset buttons, no RTC, battery connector, NAND or Wifi. As with all Olimex Devices this board is Open Source Hardware.


The board handily reads "A13-OLinuXino-MICRO".

Sunxi support

Current status





Manual build

  • For building u-boot, use the "A13-OLinuXino-Micro" target.
  • The .fex file can be found in sunxi-boards as a13-olinuxinom.fex

Everything else is the same as the manual build howto.

Mainline kernel

Use the sun5i-a13-olinuxino-micro.dts device-tree file for the mainline kernel.

Tips, Tricks, Caveats

FEL mode

The U-Boot button triggers FEL mode.


Even though the A13 does not provide DACs itself, the A13-Olinuxino has a VGA connector.

This is implemented through 3 separate DAC chips (NXP LVC244A) which are connected to the LCD0 lines. This in turn means that you cannot use an LCD and a VGA monitor at the same time, but this is ok as the A13 can only drive one display at a time anyway.

Due to the bandwidth limitations of the A13 SoC, the best resolution you can hope for is 800x600.

LCD modules

You can attach several Olimex LCD modules to the LCD connector (LCD_CON).

Expansion ports

Several expansion options are provided:

TODO: verify that the GPIO pin-outs are a 1-1 match with the A13-OLinuXino

Adding a serial port


In the top left corner of the device, there are some pins marked UART1. The pin-out is described at the back of the board. All you have to do is connect some leads according to our UART howto.
