  1. FYI getting ready to try my new motor shield, came across this.


    "However, the code running on it is really sloppy, resulting in the firmware hanging and bringing the I2C bus down whenever you look at it funny. But we are hackers, we can fix it!"
  2. I found the shield to be useless without flashing the new firmware mentioned above. The process is pretty painless if you have a 3.3V USB to serial adapter and a few pin-to-pin jumper wires.

    Also, the schematic link above is broken, and the current link on the Wemos wiki points to the relay shield schematic :(
