Our RK3328-SOM prototypes are testing now.
These are with dimensions of only 55 x 41 mm.
RK3328 SOC has:
- 4x Cortex-A53 cores @1.5Ghz
- DDR3/DDR3L/DDR4 support 1/2/4GB
- GPU: ARM Mali-450MP2
- HDMI 2.0
- CSI up to 5Mpix
- Video decode H.264 H.265 4K@60Hz
- Video encode H.264 H.265 1080p@30Hz
- Audio: I2S, Codec
- Gigabit 10/100/1000 Ethernet
- Megabit 10/100 Ethernet with PHY
- USB3.0 host
- USB2.0 host
- USB-OTG 2.0
- SPI/eMMC Flash
- SD-card
RK3328-SOM-EVB is evaluation board and reference design for RK3328-SOM:
Software support:
- Android 10
- Linux Kernel 4.4 is the official SDK of Rockchip. There is just basic mainline support with no drivers for USB3 although these SOCs are on the market for quite a lot of time.
The preliminary prices are:
- RK3328-SOM-1G (1GB DDR3L) EUR 27.00
- RK3328-SOM-2G (2GB DDR3L) EUR 37.00
- RK3328-SOM-4G (4GB DDR4) EUR 57.00
- RK3328-SOM-EVB (no SOM installed) EUR 18.00

Any reason for picking the 3328 over the PX30/3326 ? The latter having a much more modern GPU, with mainline support being developed by Bootlin.

GMAC+EMAC, USB 3.0, two USB2.0, video 4K@60Hz

Fair point, should make a compelling upgrade over the somewhat ageing A64 as well.

So you did went with the RK3328 after all, not the RK3288 or RK3399 and done so in a small custom footprint (55 x 41 mm), not SOM204 (https://olimex.wordpress.com/2017/10/03/new-universal-system-on-module-in-so-dimm-204-pin-form-factor/#comment-27664).
Have you abandoned the idea of developing SOM204 further (not enough interest from potential buyers)?

We didn’t abandon SOM204, just RK3328 has no most of the features SOM204 have, this means lot of additional stuff to complete the job, which makes circuit complicated and expensive.
About RK3288 and RK3399 these are power hungry SOCs that need heatsink and feeding high currents through SODIMM connector is not so good idea.
Many customers were asking for board with more decent Android support because there is plenty of cheap Java/Android developers compared to Linux developers 🙂 Allwinner A10/A13/A20/A64 have Android 4 which is way too old, so RK3328 with Android 10 support is an good option for these customers.

Oh, so we might perhaps expect Olimex DIY mobile phones running Android soon 😛

When do you think boards will be available for purchase? also when will you have info files on Github? thank you very much.
Apr 15, 2021 @ 09:43:50
There is lot of work on the software side, I guess not early than June. Sure there will be documentation on GitHub like for all other SOMs

I almost thought, you’d given up on Rockchip parts. Do you intend to make a board or module with RK3568 at some point, that fully uses its potential, in particular, ECC RAM, E-Ink display support, SATA and PCIe interfaces? I recently read, that there’s going to be mainline Linux support for this chip rather soon.

with the current state of semiconductor industry is hard to plan any new boards

Noname, judjing by the progression so far, you’ve guessed correctly the next Rockchip part! Here’s why:
1) Olimex has 1 existing Rockchip board – utilizing RK3188
2) The now announced board will be using RK3328
From these two, we can observe the following dependencies:
– The first number in the RK part code of each successive Olimex board stays the same – 3
– The second number increases with 2 (1 -> 3), hence the next one will be 3+2 = 5
– The third number is a bit tricky – starting with 8, it is increased by 4 = 12, but because it needs to stay single digit, a modulo 10 operation is performed and we get 12%10 = 2 – the next one would then be – 2+4 = 6
– The final number, similarly to the first one, is so far always the same – 8
So from these, it clearly follows that the next Rockchip part for Olimex to use would be RK3568.
Congratulations for craking the code, the recruiters from the hidden Olimex branch might contact you. You will easily recognize them, as they are the Men in Red (MiR) and are pretty distinctive with their red coats (occasionally mistaken for Santas during the winter period).
