You obviously did not read the other posts. You can not run this at 4.5 volts.
It will not regulate and will draw more current.

You are right the LEDs should be pulled up to VCCIO. I would be vary cautious about using this to translate to 1.8v. Depending on how you drive your VCCIO (I was just using a resistor divider from the 5v). You will get bleed through of the VCC through the leds and will hike up the VCCIO. I removed the LED resistors and now translates to correct levels.

It does not look like they brought out the ID pin. Why? This is my biggest complaint with all your breakout boards, if you are going through all the trouble of building a breakout board why don’t you bring out ALL the pins? I see this issue on the MMC/SD breakouts also which seem to be limited to just the SPI signals and not the full 4bit interface …DUMB!
News - BatchPCB Gets a Feature

Don’t get me wrong. I totally love the concept of community driven PCB development and I agree the price can’t be beat. The thing that rubs me is an advertised price of $5.00 that cost $30+ to get to your door. Thats more then a 6X difference! And yes I know most of these costs are not under Batch’s control.
Not such a great deal. For a $5.00 joy stick PCB they charge $10.00 handling and thats not including shipping!.

I love the fact thay put in the VCCIO jumper. I am interfacing to a 1.8 volt system and use this functionality. Unfortunately the LEDs are also both pulled up through VCCIO and both remain constantly lit when operated with VCCIO at 1.8v. They should have pulled up the LEDs through the dedicated 3.3 volt regulator.

yea, RGB interface is the standard stuff. Thats not the problem. The controller requires quite a lot of setup via the SPI to get the pin pads setup for the proper drive as well as other things. The initialization sequence is quite extensive. I would like to see an example, app note or even the HD66790 datasheet. There seems to be nothing available on the web.
Nix the zebra.
Looks to be a Samsung product.
More then likely it used a Zebrastrip for the connection.
No public wish lists :(
