Linux powered STMicro STM32MP1 Solder-down QFN-Style SoM Measures 27x27mm

STMicro STM32MP1 Cortex A7/M4 processor was launched last year with support for Linux and Android. Since then we’ve seen a few STM32MP1 SBC‘s, development kit and modules,  with some of the latter really compact with DHCOR STM32MP157 SoM found on Avenger96 board measuring just 29x29mm.

Direct Insight has now unveiled QFN-style solder-down QSMP systems-on-module based on STM32MP1 that measure just 27 x 27 x 2.3mm and manufactured in Germany by Ka-Ro Electronics.

QFN-style SoM

The base of the module functions as both a ground pad and a thermal conductor. The large solder pad underneath is also used to
hold the component at a defined height during soldering,
without the solder being compressed by the weight. The company claims the module is suitable for 2-layer baseboards. Details about soldering and baseboard layout guidelines can be found in the datasheet.

The QSMP module is said to come with a dedicated development system and a Linux BSP. The development kit includes a QSMP-1570 module with dual-core ST32M157C processor, 512MB RAM and 4GB eMMC, an RGB connector for a touch screen, as SD Card socket, as well as Gigabit Ethernet and USB host ports.

You’ll also find a debug UART port, and all 100 module pins are brought to a 2.54 mm solder pads.

The module and development kit are available now, but pricing has not been made public, and instead, you’re being asked to ask for a quote on the product page. As a side note, you may see some reference to “STMicro ST32M1” and “ST32M151A, ST32M153A, ST32M157C” in the aforelinked page and some news sites, but there aren’t any new “ST32” processors, those are just typos…

    1. I don’t understand why you would buy this. There is 0 public documentation and probably 0 software support as well. Similar to most chinese SoCs.

      1. >I don’t understand why you would buy this.
        Ugh, because if you want something like this STM32MP1 QFN module maybe you’d be interested in some weird takes on the same theme? For a person that reads a site like this your imagination is a bit lacking…

        I’m trying to mainline support for this family of chips at the moment.

        1. It’s not like I am not interested in chinese ICs (because I really am). But I usually stop tinkering if even chinese forums don’t have any information about a specific one available (which is the case for the SSD201 according to your table and also after looking at two forums myself). Maybe it’s just me but I don’t know how you are supposed to move forward if literally there is no information available? How are you doing it?
          That said, there are some Cortex A7 SoCs from Allwinner which are supported by linux sunxi / Olimex. There also is the Mediatek MT6572 with a large datasheet / register definition available which is also a dual core A7 (not with integrated memory though).
          Edit: It seems like you did a lot of work reverse engineering. Big respect to you.

            I have the pinouts and databriefs for the SSD201 and SSD202..
            The SDK has leaked on github already too. They are basically the same as the other chips in this family so most of the hardware is worked out.
            >How are you doing it?
            I was manually poking registers and pins previously but now github’s code search returns a bunch of kernel etc sources that have been uploaded and I think aside from the video encoder/decoder stuff and the NPU the source for everything useful is in the wild.
            Someone even uploaded the minutes of internal meetings about the development of some of these chips. :p
            >That said, there are some Cortex A7 SoCs …
            >(not with integrated memory though).
            QFN with memory is the niche. The only things around are SoMs like this which are expensive, the sigmastar chips and one hisilicon part from what I can tell.

          2. That’s very interesting. Thank you. Nevertheless, the SSD201 doesn’t seem to be available for purchase anywhere (besides your linked devkit)?

          3. Yeah availability is a bit of a problem. That said modules like this are usually hidden behind a “contact us for a price” link so it’s not vastly different. I did write “cheaper if you can get them” in my first comment 🙂

    1. The page won’t load here. What’s the starting price?
      Edit: Had to use a UK VPN. QSMP solder-down QFN style module with STM32M151A: $30.24
