RK3188-SOM Quad Core Cortex-A9 running at 1.6GHz System On Module first prototypes work fine


May is the month of our System On Modules πŸ™‚


Today our next SOM with RK3188 successfully was tested and OK.

This one is little beast comparing to A20 it have 4x Cortex-A9 vs 2x Cortex-A7 and runs on 1.6GHz vs. 1GHz so RK3188 makes total 16000 DMPIS vs. 3800 DMIPS for A20 (4.2 times faster) and vs. 965 DMIPS for RaspberryPi (16.6 times faster).

On the SOM there is:

  • RK3188 running at 1.6Ghz
  • 1GB DDR3 memory
  • Power Managment Unit IC
  • optional 4GB NAND Flash
  • micro SD-card to boot Llinux or Android
  • two buttons
  • three status LEDs
  • debug UART console
  • 5 GPIO connectors 2×20 pins 0.05″ step

RK3188-SOM and RK3188-SOM-4GB will be available for sale in June. The price of RK3188-SOM will be EUR 40 / 1000 pcs, the price of RK3188-SOM-4GB will be EUR 45 / 1000 pcs

RK3188-SOM-EVB is also available with Eagle CAD files, so any one can tailor board to his needs:


The RK3188-SOM-EVB reference design have:

  • RK3188-SOM-4GB module
  • 4x USB Hosts
  • 1x USB OTG
  • HDMI output
  • 100MB Ethernet
  • RTC with backup battery
  • LCD connector compatible with A13-LCDxx A10-LCDxx, A20-LCDxx displays we have
  • 2x UEXT connectors
  • 2x 40 pin GPIO connectors

RK3188-SOM-EVB will be available for sale in June too and the price is EUR 85.00

Android and Debian Linux will be provided.

    No sata port ?

    power consumption?

    when can we order this SoM ? any ETA

    At last, enough power for my hobbyist, unoptimized, memory-eating computer vision programs! πŸ™‚ Just in time for my birthday! πŸ™‚ That’s way smaller than my laptop running OpenCV. Do I get both the EVB and the SOM for € 85? Do you think it will run Picuntu? Thanks

    Real Time kernel supported by Olimex?

    RK3188 is faster but also hotter than A20 and this might be a problem considering the current design of SoM+EVB where it is not possible to install even a passive cooler.

      we will do some power measurements today, but so far we didn’t noticed RK3188 to heats
      Do not forget RK3188 is made on 28 nm proces while A20 uses 40 nm process

        Ok. I’ve noticed that alot of chips are very cool until you utilise the Mali core or try to run HD video decoding. And how about doing 3D graphics and playing HD movie AND running some multicore heavy load apps in backgroung? I think in small enclosure that could be a problem. Btw. I like to wach a movie while linux builds in background.

    Is there an I2S support? RK3188 has 2ch 16/24/32bit up to 192khz i2s
    can we just pick a signal from gpio-s? what about software?
    btw specs are great and price is ok.

    Now, it’s time for the quad-core Atom-based x86-OLinuXino for even more performance (and, finally, after all the Chinese SoCs, publicly available long processor data sheets and open source graphics with public GPU documentation)! πŸ™‚

    Need moar ram! MOAR!
    But seriously, rk3188 allegedly supports up to 4gb, though 2gb is common.

    How is the linux situation on RK3188 compared with A20? Do we have all the sources?

    I need an EVB for a project. No other board in the market is both open and powerful enough for it. I’d like to be among the first to buy it. Can I preorder it? Does the first board have the number “1” printed on it? πŸ™‚

    Is it released? Will Linux OS be supported with hardware accelerated video codecs

    Is the full RK3188 Specification Datasheet Technical Reference Manual available anywhere yet?
