** All three boards have the option to work with MOD-WIFI_RTL8188, which is USB WIFI
modem with RTL8188CU chip and can be purchased separately. MOD-WIFI_RTL8188 can be
connected to any of the OLinuXino boards via the USB.
*** OLinuXino-MINI has additional option of having RTL8188CU hardware mounted! If you wish
RTL8188CU embedded in the device you should purchase OLinuXino-MINI-WIFI. Choosing the
embedded WIFI option will leave your USB-HOSTs available for use.
1.2 Target market and purpose of the board
The boards from the OLinuXino family are ready to use, easy to setup and are suitable for
embedded programming enthusiasts, Linux hobbyists, gadget fans and also professionals (since its
low cost makes it very good solution for application orientated embedded systems). The main usage
of the board is software embedded development without the urge of understanding perfectly the
hardware.

OLIMEX© 01 OLinuXino User's Manual
The strong points of the boards are the processor speed, the mobility of the board and the low price.
Customers have full access to the technical documentation of the board. The software is released
under General Purpose License and the board is considered open-hardware.
1.3 Organization
Each section in this document covers a separate topic, organized as follow:
–Chapter 1 is an overview of the board usage and features
–Chapter provides a guide for quickly setting up the board
–Chapter 3 contains the general board diagram and layout
–Chapter 4 describes the component that is the heart of the board: the iMX 33
microcontroller
–Chapter 5 is an explanation of the control circuitry associated with the microcontroller to
reset. Also shows the clocks on the board
–Chapter 6 covers the connector pinout, peripherals and jumper description
–Chapter 7 shows the memory map
–Chapter 8 provides the schematics
–Chapter 9 contains the revision history, useful links and support information

CHAPTER 2 SETTING UP THE OLINUXINO BOAR
2. Introduction to the chapter
This section helps you set up the OLinuXino development board for the first time.
Please consider first the electrostatic warning to avoid damaging the board, then discover the
hardware and software required to operate the board.
The procedure to power up the board is given, and a description of the default board behavior is
detailed.
2.1 Electrostatic warning
OLinuXino is shipped in a protective anti-static package. The board must not be exposed to high
electrostatic potentials. A grounding strap or similar protective device should be worn when
handling the board. Avoid touching the component pins or any other metallic element.
2.3 Requirements
In order to set up the OLinuXino optimally, the following items are required:
- 6V to 16V source of power with 1A maximum amperage.
- SJTAG interface programmer
- USB keyboard
- Monitor with composite interface or Personal Computer + USB-SERIAL-CABLE-F
- SD card with Linux image
Note that the board arrives without SD card or Linux image. You can purchase a card with Linux
separately. It is recommended that the user has basic Linux experience.
Some of the suggested items can be purchased by Olimex, for instance:
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)
SY0612E - power supply adapter 1 V/0.5A for iMX 33-OLinuXino-MINI

2.4 Powering the board
The board is powered either via the PWR jack or via a battery. It should be supplied from a 6V to
16V source with maximum current of 1A from the power jack.
All measures below are taken at 10V.
If measuring the current consumption it should be around 0.06A before initializing all the
peripherals. The consumption raises to 0.1 A without WIFI and USB hosts initialized and Linux
running. The consumption goes up 0.15A with the Linux running when WIFI and both USB hosts
initialized.
If you have a standard USB flash drive attached to a USB host, Linux and WIFI running the typical
consumption is around 0. 0A.
When powered by the typical 3.7V battery the WIFI and USB-hosts will be disabled if you use
external 3.3 DC-DC (not mounted by default).
For the European customers we sell a power supply adapter 1 V/0.5A - SY0612E.
2.5 Prebuilt software
Note that the boards arrive without Linux or SD card. The Linux i age can be purchased
separately on a SD card or you can built and write it yourself.
When we program the boards we change the default position of the following HW_OCOTP_ROM0
fuses of the processor:
SD_MBR_BOOT(3) - Blown
SD_POWER_GATE_GPIO( 1: 0) – 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.

2.6 Using BitBurner
IMPORTANT! MODIFYING THE FUSES IS IRREVERSIBLE PROCESS! BURNING THE
WRONG FUSES MIGHT DAMAGE OLINUXINO IRREVERSIBLY! BURNING WRONG
FUSES MIGHT CAUSE BOOT PROBLEMS!
BURN FUSES AT OWN RISK!
The bit burning is done via the USB of the computer connected to the OLINUXINO board and the
BitBurner software. To be able to burn the fuses you will need to make a custom cable that connects
a USB with the 3 pin holes found at the bottom of the board named “GND”, “DP”, “DM” (check
the picture below for a better view how the three wires must be connected.
After soldering the three wires you can place a marker on each of them or use colored wires to be
able to distinguish them. You can also use some gel to keep them tight on the USB connector. On
the opposite side of the cables you might place 50mil (1. 7mm) male connector following the order
of the signals. Please also restrain from using wires longer than 0 cm since that might make the
connection unreliable.
Download BitBurner from https://www.olimex.com/dev/OLINUXINO/iMX 33-
OLINUXINO/BitBurner.v1.0.4.6.zip. Extract it and start the .exe. If you connect everything you
should see and choose HID-compilant device from the “Select device” drop-down menu. If you
check the fuses we have already burned the application should show an image as the one on the next
page.
