LoRa Remote Alarm Transmitter

Another one of my LoRa device projects, been having a lot of those lately:) This one has the need to have an onboard relay, as well as inputs for sensors on a single PCB. I also have the requirement that this unit has to be powered from 12v. I made use of on-PCB heatsinks for the two voltage regulators, as well as used my reliable N-MOS based level converter circuit to convert signals to and from the RA-02 module and the Atmega 328/168/88/8a MCU. Full optical isolation ( Not Galvanic ) is provided on the relay driver as well. Well manufactured, Looks great, thank you

    Custom onewheel pint x battery box. Excellent print and material build. Great customer service. Exact fitment for project. Will use for future projects
    Properly manufactured and good quality PCB, all the component placement was okay and properly soldered.
    Very impressed with the build quality. The fasteners fit like a glove into the threads and countersinks. The plate is even smoother than I expected. It does have visible milling marks (as expected)...
