    Going OT here a bit... I just posted benchmarks for RPi 4 maker board and Compute Module

    Passmark Performance Test Results:

    OrangePi Zero2 Cortex-A53 (aarch64) 4 cores @ 1512 MHz | 984 MiB RAM Number of Processes: 4 | Test Iterations: 1 | Test Duration: Medium -------------------------------------------------------------------------- CPU Mark: 453 Integer Math 10026 Million Operations/s Floating Point Math 1397 Million Operations/s Prime Numbers 2.7 Million Primes/s Sorting 2054 Thousand Strings/s Encryption 131 MB/s Compression 3117 KB/s CPU Single Threaded 214 Million Operations/s Physics 49.2 Frames/s Extended Instructions (NEON) 186 Million Matrices/s Memory Mark: 328 Database Operations 234 Thousand Operations/s Memory Read Cached 2701 MB/s Memory Read Uncached 1712 MB/s Memory Write 3691 MB/s Available RAM 844 Megabytes Memory Latency 169 Nanoseconds Memory Threaded 1832 MB/s --------------------------------------------------------------------------

    The system averaged just under 15MB/s storage write speed using a Samsung 32GB class 10 MicroSD card. If high-rate disk I/O is typical of your application, you may consider using a system with on-board eMMC, or that offers an alternate interface (PCIe/SATA/NVMe).

    Looks like the OS problems lets the Espresso down.

    The OS issue redeemed itself pretty quickly using ARMbian, and after getting comfortable with what I was doing (I hate just typing in commands from a set of instructions), but from the perspective of documentation, I'd have to agree: GlobalScale lets itself down with dated OS images and incomplete instructions. Anyone who would not find that the ARMbian project separately publishes an up-to-date Debian/ARMbian for this board would be really disappointed and may discard or return it.

    @a-lurker said in RPi Alternative: ESPRESSObin V7:

    Any sockets for an internal SSD or would the USB 3 socket be taken up with an external SSD?

    The V7 boards have a SATA port inside. A common complaint about the case is that it leaves almost no room for any SATA drive or module. The SATA connector is vertical on the board, and indeed, the SATA modules I have would all be too tall to fit in the case without chopping a hole in it. But it's there. There's also a Mini PCIe connector, but I can't find any statement that it can be used for storage (I suspect it could, perhaps with work, as detection is more of an kernel/software issue than a hardware issue). USB 3.0 would also be an option.

    The board has provision for eMMC, and more RAM, but I don't see any models that have it. That may be something they make available when you order a custom lot.

    Some take a 2 mm central pin and others use a 2.5 mm pin.

    Indeed! This is a 2.1mm inner.

    About power. I’m just using a usb cable attached to the Ethernet cable, going back to my rack, where I have a Zwave switch doing 20-80 cycle automatically. I’m using FullyKiosk and it’s http and mqtt api. You can switch it on/off, dim the screen, open apps and pages automatically.

    Not quite sure.
    However when I set up my 3B+ I had been using it for a couple of weeks with an SD card including z-way.
    I just made an image with Win32DiskImager of the complete SD and copied it to the SSD and it worked.
