RK3188-SOM, RK3188-SOM-4GB and RK3188-SOM-EVB are in stock now!


RK3188-SOM and RK3188-SOM-4GB system on modules are now in stock, these modules have same size as A20-SOM 81.28 x 55.88 mm and use same 0.05″ connectors, well they are not exchangeable though.

RK3188 is quad core, Cortex-A9 running at 1.6GHz. What does this means? Comparing to A20 you can expect everything to run about 10 times faster.

As power requirements, it takes more power than A20 obviously you pay for the performance and the higher clock rates.

For these who want to make their own board we made RK3188-SOM-EVB template with:

  • HDMI
  • 100Mb Ethernet
  • x4 USB hosts
  • RTC clock and backup battery
  • +6-16VDC power supply
  • LCD connector where you can connect LCD-OLinuXino-XX LCDs
  • 2x 40 pin 0.1″ step GPIO connectors

RK3188-SOM starts from EUR 35 for 1000 pcs and it’s probably least expensive quad core Cortex-A9 1.6Ghz module on the market, the RK3188-SOM-4GB starts from EUR 40 / 1000 pcs.

The evaluation board RK3188-SOM-EVB cost EUR 70

    Does it have SATA?

      RK3188 SOC does not have SATA support or any other fast enough bus that can be converted to SATA with full speed (there is only USB which is slower than SATA) so no SATA on the SOM and EVB.

    EVB price in shop is 70 EUR – first night promo, or a mistake in the blogpost πŸ˜€

    10 times faster is absolutely appealing πŸ™‚

    Asking if there is good documentation (possibly written/edited by Olimex) available to allow to drive it properly ? (Especially from the HAL-makers standpoint).

    Any plans for RK3188-OLinuXino-LIME?
    LIME form factor, RK3188, 1 GB RAM, 1-2 USBs more instead of SATA port, 50-60 Euro price

    Will we have a OLinuxXino with this RK3188?

    Now that the new Raspberry Pi 2 is a quad-core ARMv7, this RK3188 may be the nearest thing to a SoC that can compete with Pi in the way that the LIME series did previously. This System On Module isn’t positioned that way, but more for an industrial audience.

    I think it would be surprising though if Olimex didn’t have something up their sleeves to address the changed situation in Pi vs LIME.

    How much memory speed is the 3188 achieving, so far ?

    10 times faster? In terms of pure multithreaded GHz power, we get

    4 * 1.6Ghz = 6.4 (for RK3188)
    2 * 1GHz = 2 (for A20)

    And yes, Cortex-A9 is somewhat faster than Cortex-A7 per MHz, but that’s just a few tens percents at most. So the realistic performance improvement estimate is more like “only” 4 or 5 times faster πŸ™‚

    Cortex-A7 is 1.5 DMIPS/Mhz Cortex-A9 is 2.5 DMIPS/Mhz x 4 cores x 1.6 clock difference it’t above 4 times

    the 10 times faster is based on tasks we run on A20 and RK3188 on later they take 10 times less time, so it may be also the bus settings, memory IO etc.

    right! still calculation is correct 2.5 * 4 * 1.6 = 16 / 2 * 1.9 * 1 = 16 / 3.8 more than 4 times faster just the core


    • SK

      I think it will be more correct to advertise it as roughly 4 times faster compared to A20 purely technically then πŸ™‚

      And after that you could mention that your particular 2 SOMs based on the 2 chips can have as much as 10 times difference and the work/tests at wich this was mesured (and any settings if applicable). πŸ˜‰

        thechnically one SOC is not just the core πŸ™‚
        when one job takes 20 minutes on A20 but 2 minutes on RK3188 I call this 10 times faster πŸ˜‰

    “when one job takes 20 minutes on A20 but 2 minutes on RK3188”

    I would call it an anomaly, which requires further investigation πŸ™‚ Could you please provide more details about this particular use case?

    I got issue with “RK3188-SOM Debian for microSD card – kernel 3.0.36+ – release #1” (more details https://www.olimex.com/forum/index.php?topic=4308.0).
    Does anybody try this img?
