The first kits rev 0.7 are up for grabs

Hello,

I have been overloaded with messages and e-mails since i have posted some pictures of the new revision of the mcHF. Apologies if i have not been able to answer or too slow, but switching to the new revision kit was huge logistical operation, even with the help of Lucy.

The first batch of Components Kit is ready, please check the Order page for detailed information. Just a few things though – we have planned to supply those kits with the case, but due to being sourced by four different suppliers, not everything is ready in time, so i am sorry. Will have to list it separate on a later date. Also i haven’t uploaded pictures of detailed boards assembly and the case yet, this is to come as well.

The current kit comes with three boards, six bags of parts, again SMD and post assembly. Also the kit will include speaker, the nice optical encoder and LED lit buttons. Maybe in the future we will resort to cheaper option – like mechanical replacement for the optical encoder and keeping the optical as a option, not supplying the speaker and using the older style buttons (footprint fits fine), all this to drop the kit cost down. Depends on how this revision would be met by fellow hams.

If you’ve been waiting, please check the Order page, the quantity is limited, but i hope to have the next batch before Xmas, all depends on how fast we can get parts during the busy period.

Edit: I forgot to mention that all kits from now on will come with CPU installed and programmed, as this was the main complaint by OMs – difficulty of loading the bootloader and firmware.

    So, Chris

    there is no actual regulator that outputs “LOGIC_5V” as such.

    What happens instead is that “VCC_5V” from U4 becomes “LOGIC_5V” after the transition through P1b.

    And the same I guess for LOGIC_3V3 and LOGIC_8V

        Understood. A bit confusing initially but since i only want to build part of mcHF, a need to better understand things a bit more !

    Can u advise on the HY32D display. Can it be run in SPI mode also? I see on the Schematic a reference to Low Speed interface. It’s not clear on the Sch or even the data i found for the HY32D if SPI is possible.
    There appears to be no jumper on the HY32D for selecting SPI/Parallel.

    This is the display I bought.

      Hi,

      The HY32D does not have SPI interface (there is serial for the TP interface only). The one you link to it seems a copy of it,
      but not sure if they ‘modded it’ to have a serial, doesn’t look like from the pins.

        OK Thanks Chris,
        The reason I ask, is I am considering using this display and loading some of the 0.7 circuitry as a Panadapter only.

        Is the German groups software compatible with vers 0.7 boards?

          Hi Glenn,

          Yes, rev 0.7 is compatible with rev 0.6 schematics, very minor changes, so if a firmware that runs on 0.6 should
          be ok on the new revision.

            Thanks Chris
            Sorry to be a pain but i am having a hard time finding where the “LOGIC_5V” net comes from.
            I can find U3 which is VCC_8V net
            U4 is VCC_3V
            U5 is VCC_3V
            U206 is UI_3V_MCU
            U208 is USB_3V

            But no LOGIC_5V source on any of the schematics.
            Glenn

            2 typos on my post
            U4 is VCC_5V
            U208 is USB_5V

            I did a search on the all the Sch pdf files but can’t find LOGIC_5V source.

    I looked up the Alps switches (Alcoswitch) in the BOM, at Farnell but they appear to have no actual button or LED under the part number you give.

    Is there another number for the button/led assembly?

        Hi Chris, that seems to be the part I guess you used, but the picture shows no push button insert with led etc. Juts the bare switch

      Hi Brian,

      Sorry about that. For the next batch we should have much bigger quantity and regular stock (as before). Switching to new revision is always painful and takes a bit of time.

    Hi,

    Looks good – thanks for all the excellent work on this – any rough estimate when the bare 0.7 boards will be in stock again please? (as I already have most of the components in the form of a 0.6 kit)

      Hi,

      I don’t have the price yet, still waiting for the boards from factory. The housing is with me,
      but not complete,some components i am still waiting on.
