    Default Introducing the HGI80 alternative - the latest DIY kid on the block

    A few of us in the background have produced and tested a new DIY hardware platform that acts exactly like an HGI80. Think of it as an advanced version of the NanoCUL.
    The idea was to create a platform that was cheaper and easily available. One that could be put together using off the shelf parts. There is just one custom PCB that basically "glues" all the other parts together. Ofcourse there is no real need to purchase the custom PCB, you can even put this together on a breadboard or vero board.
    I've attached a few pictures to show you what it looks like in parts as well as a fully assembled unit.
    If you are interested in a board, put your name down in a list below and one of us will get in touch with purchase details. At this point, you need to be able to / be comfortable soldering 2mm pitch components.
    If and when a fully assembled unit is available to purchase, I will update this thread accordingly. For now, I am just looking for interest. So mark, if you want just a PCB or if you are interested in a fully assembled unit.
    I will list out all the parts needed to put a complete unit together.
    When plugged it, it will work just like the HGI80 and so is directly interfaced with Domoticz, Home Assistant, OpenHAB etc. You can also use the brilliant evohome_rf transport that basically decodes most of the Evohome radio messages.
    In addition to the custom PCB, you will need the following parts.
    1. SS Micro (a small USB Arduino board)
    2. CC1101 868MHz module (Red or Green)
    3. SMA socket, if you want to use a proper antenna
    4. 868Mhz antenna
    The Green CC1101 modules come with a pig tail antenna that is acceptable.
