iMX233-OLinuXino-NANO user's manual
SY0605E - power supply adapter 5V/1A for iMX233-OLinuXino-NANO (50Hz utility frequency -
for EU residents only)
SY0605E-CHINA - cheaper power supply adapter 5/1A for iMX233-OLinuXino-NANO (50Hz
utility frequency - for EU residents only)
iMX233-OLinuXino-SD - SD card with the Linux image
USB-SERIAL-CABLE-F - USB serial console cable female (check “6.1.1 UART Debug” for info
how to connect it to the board)
BREADBOARD-1 – relatively small breadboard (82x52x10mm) that allows easy access to the
GPIO pins via jumper wires (no soldering required)

2.3 Powering the board
The board may be powered via a 3.7V Li-Pol battery connected to the LIPO BAT connector or
using a 5V external power supply on pins 1 and 2 of CON2 connector. When powering the board
from CON2 it should be supplied with a 5V with a maximum current of 1A.

from CON2 it should be supplied with a 5V with a maximum current of 1A.
Note that there is a built-in battery charger the iMX233 processor.
When the board is powered only by a 3.7V battery the USB would NOT be able to power USB
devices since there IS NO step-up convertor (to 5V).
devices since there IS NO step-up convertor (to 5V).
It is a good idea to have a power supply providing minimum of 0.2 A.
If measuring the current consumption it should be around 0.06A before initializing all the
peripherals. The consumption raises to 0.12A if performing a task without additional peripherals
connected.
peripherals. The consumption raises to 0.12A if performing a task without additional peripherals
connected.
If Linux enters seep mode the consumption goes down to 0.01A.
2.4 Prebuilt software
Note that the boards arrive without Linux or SD card. The Linux image can be purchased separately
on a SD card or you can built and write it yourself.
on a SD card or you can built and write it yourself.
Currently the official iMX233 Linux image is based on Debian. It replaced the Archlinux
distributions used before.
distributions used before.
When we program the boards we change the default position of the following HW_OCOTP_ROM0
fuses of the processor:
fuses of the processor:
SD_MBR_BOOT(3) - Blown
SD_POWER_GATE_GPIO(21:20) – 10-PWM3
SD_POWER_GATE_GPIO(21:20) – 10-PWM3
For burning the fuse position we use the BitBurner software. This operation is discussed in details
before. Proceed with great caution when burning fuses since it is irreversible operation.
