    Quick update.

    After the initial version was made, I found a few minor issues. All issues are resolved in V1.2

    • Added battery charging functionality, so you can use this module with 3.7V LiPo battery powered. It handled by MCP73831 chip. JST 1.25mm 2P is used  for battery connector.
    • Change PCB color and tidy up top silkscreen 2x13P connector


    Results so far :

    • PCB assembly succesfully, and quite easyly done by hand-soldering
    • Upload code done using Arduino IDE
    • Two Way Ranging tested perfectly in indoor, but for some reason the zero distance reported as 30cm. Maybe need to calibrate the antenna.

    Please take a look the project github link for the schematic, gerber file, and sample code for the current mile-stone.
