...the HDMI tracks goes direct to the RK3288 (only the ESD protection there)...

Thanks so much for the detailed pics and info!

Ah looks like I was not clear.

RK3288 has a HDMI transmitter built into the SoC.
"HDMI2.0 to support maximum 4Kx2K display" [RK3288 SoC - Video Interface]

If the current versions of the RK3288 are not HDMI 2.0 capable, then will there be a new hardware revision later? That seems very expensive.

Alternatively, they could include a separate chip like on RK3188 boards.

If the RK3288 is already is HDMI 2.0 capable, then its a matter of updating firmware/driver support.

The RK3188 does not support HDMI from SoC, that is why they use the IT66121FN. The RK3188 has 2 LCD called LCD0 and LCD1 that send the RGB 24bits, Enable, Clock, Vertical syncronization and horizontal syncronization. They just take one of the LCD and convert to HDMI through the IT66121FN:



But this is because RK3188 does not manage the HDMI directly (while the RK3066 and RK3288 can). You can see from the pictures I posted before about a RK3288 board, the HDMI tracks goes direct to the RK3288 (only the ESD protection there):




Specifications say:

• HDMI2.0 to support maximum 4Kx2K display

So it must be HDMI port managed by the SoC directly.

Nope its a HARDWARE upgrade 2.0 all HDMI cables will work with 2.0 and 2.0 is backwards compat with previous versions of HDMI.

If your looking for a UHD product it must have 2.0 for now and the future.

Lets hope that companys are sensible and will wait for HDMI 2.0 as there a few companys who have got and will get supplys very soon.Products with 1.4 will seem pointless.

Isn't HDMI 2.0 simply software + hardware driver? The connecter is physically the same so anything that ships now should be able to be upgraded to 2.0 or am I missing something?

Here is a small video. This board boots Android 4.4 in around 17-18 seconds

Is that a production run....solder points look rough.

It's the latest test board (and definitive). Now working over software.

I just received a new "toy" in the office:



I'll share more info as soon as I can... these days I have lots of products over my desk

It appears the wifi versions are available. I just ordered one from Geekbuying.com today.

I'm looking forward to doing some ROMs for it very soon.

yes, the wifi version has arrived in our ware house, but just very limited stock, pipo hasn't released the enough stock, budy. stay tuned, we will written some reviews, and play it a lot.

let's check the rk3288 performance in the tablet first.
