DIY Beagle Board

Does anyone know how to get the exact chips on the beagleboard BOM
list? I'm planning to tinker with the schematics a little bit to
physically fit a project. Any help and advice will be greatly
Thanks in advance.

Just download the BOM from The OrCAD schematic is also available,


Here are the links ofr the BOM and the schematic:

You may have great difficulty getting the POP memory devices used on the beagleboard.


I’ve just finished a complete design with Omap3. The only issue I had was with getting the TWL4030, so I used another power chip -
TPS65023, which is readily available.
I also used off the shelf DDR mobile ram, and NAND Flash - because I was not able to get the POP memory (my company is too small to get any attention from samsung or Micron).

The problem with such a design is the PCB - it cost me, the samples only, around $8,000, this is because of the 0.4mm bga, and having to use filled blind vias in pads with hole size of 6mil, I used 8 layers, and the total size came out to be 4x6cm.

I suppose to receive the first two assembled boards next week, and I hope they work :slight_smile:

Will post here as soon as my board works.

I could have helped on the POP side with a few samples. What DDR and NAND did you use? It would be helpfull if you used what was in the POP devcies to save you form having to modify the code to support a different device.


My BOM is:

NAND: Micron MT29F1G08ABBHC-ET:B VFBGA63 128Mbx8 1.8V (available

DDR: Micron MT46H32M32LFCM-6:A TR VFBGA90 Mobile DDR SDRAM
(available at digikey) 8Meg x 32 x 4 banks = total of 128Mbyte

As soon as I have the system running, will post the intialization code
and the schematics, if somebody interested.

How many DDR devices are you putting on your board?


I have only one DDR on my board. It is 32 bit DDR.

Sounds good!


And here is my board - just received it 3 days ago from the fab:

Had some mistakes, but luckily not critical. Able to communicate with
JTAG to the omap3.


Looks great!!! Keep us posted on your progress.


What will I have learn to start experimenting with the architecture
and PCB. What software will be best for this kind of work
and how much it will cost (the software). I am an electronics engineer
working in embedded software(Unlucky not PCB design) with Honeywell.
How many layers have you used for this design?

Thanks in advance,

Looks really beautiful, I didn't find any DVI or HDMI connector on
this other than composite video.

can you please confirm the same. What kind of sensors are you planning
to interface to Camera module?

Great work..


Nice one! Any idea on cost of reference design (including H/W and S/W)?


Layers - 8
PCB design - there are few good ones out there... Pricing of PCB
software - do not know...

Hi Khasim,

Thanks :slight_smile:

Have on board only single composite video out, no DVI, and no HDMI.
Cameras - going to use a camera module, e.g. :


The BeagleBoard is 6 layers. All of the design material for beagle is on the site. There is also an OMAP PCB design guideline that can be downloaded as well at The .4mm and the .65mm packages are available at this location.

As to layout tools, they won’t be cheap. We use Allegro on beagle, but there are several other good ones out there. You might be able to find some used packages out there that will work for you and save you some money.


Hi Nazu,

It is still too early to offer this as a reference design, and I
cannot support it as good as beagleboard is supported. I have no
intentions of competing with beagle / bSquare / Mistral etc...

Basically I do not mind to sell it later, when I manufacture more, on
"AS IS" basis, along with schematics, without much profit, and make my
profit on adaptations / changes / SW if needed.

Some of the differences between my board and beagle:

1. The most important difference is that ALL components which I use
are readly available (without having to sign NDA or similar
privileges). They are available to order directly from digikey, mouser
and arrow, and all are available in stock.
Pricing of my board scaleable - can choose smaller memories, and not
to install some other components (e.g. not USB, no Audio).
I use standard micron mobileDDR, standard micron flash, and instead of
the TWL4030 I use tps65023 (off the shelf low cost power chip).

2. Digital camera connector (actually two)

3. Piggyback connector to another board (which is NOT yet developed)
to have ethernet, analog video input, and I/O in the future.

4. TWO SD connectors (one I shall be using for SD-WiFi, and the
microSD connector shall be using for Flash)

5. Connector for CEATA hard disk (otion)

6. Smaller size.

Things that I do NOT have:

1. My USB is capable of working only as a slave.
2. Have not DVI video out.
3. No audio input (although I have microphone on board)



I will disagree with you on one point. There are no parts that are used on Beagle that require and NDA. The Micron part is the only part that could be in question, but Micron is working to put that information on their public website. Even today you don’t have to sign and NDA to get that information. There is an easy way to contact Micron direct to get that information.
