This OLinuXino development board enables code development of applications running on the i.MX233 microcontroller manufactured by Freescale Semiconductor.
iMX233-OLinuXino-MICRO is 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. It allows embedded software development without fully needing to understand the hardware side. This board is suitable for breadboard use via 60 GPIO pin pads.
There is no voltage regulator. The board must be supplied with regulated 5V power via its barrel connector. Unfortunately, our basic wall-mount universal power supplies do not work with this board (the 4.5V setting is not enough and the 6V setting kills the board). The easiest, no-solder solution is to get the MIKROE-192 voltage regulator/rectifier and connect the PWR-CABLE adapter to its 5V output screw terminals. Then you can use the 9V or 12V setting on the WA-VAR-US or WA-UNI power supply plugged into the MIKROE-192.
Note that you will need to download and write a Linux image. The user manual steps you through that task (or even building an image from source if you're so inclined).
i.MX233 ARM9 Board Features
- iMX233 ARM926J processor at 454 MHz
- 64 MB RAM
- SD-card connector for booting the Linux image (card not included)
- Composite PAL/NTSC video output (RCA jack)
- USB High-Speed Host (does not communicate with Low-Speed devices like many mice and keyboards; using a USB hub is recommended)
- Three Buttons
- 2×30-pin GPIO for connection to other hardware
- PCB dimensions: 3.00 × 1.70 inches (76.2 × 43.2 mm)
- Nominal dimensions: 3.40 × 1.70 inches (86.4 × 43.2 mm)
Debugging Options If you don't have a separate monitor or display around, and you don't wish to swap cables constantly with your PC, there are three debug interfaces that provide a better option for your OLinuXino experience. Pins already are provided for the U_DEBUG interface, which requires only the USB-to-Serial Cable that you can select from the Optional Recommended Products list below. Pads are provided for you to install more traditional serial and parallel interfaces if you wish to use a Freescale-compatible JTAG dongle. See the user manual for details.
Some users experience random lockups If you find that the board locks up on you frequently, removing the termination resistor at R17 will fix that issue.
