    I was not able to resist the new ceech board the and the lucky one to receive the fully populated samples last week.

    The board incorporates the hardware to solar charge a li-ion cell including the measurements for voltage & current of both solar and cell.

    To test the board I dismantled a cheap solar garden light and connected a CR123 li-ion cell.

    The result

    For testing purposed I found that it works well to connect a HC-05 bluetooth module and use a mobile phone with bluetooth terminal to read the serial port. This way I don't need to carry a PC around the house. You can see the board producing it's intelligence 😆

  • The HC-05 is a great idea. Thanks for sharing.
