Readme

This board is targeted to be used for motorized cellular shades. The board dimensions are constrained to fit inside the shade's top housing. The board has a current sensor to monitor the motor strain to tell whether the shade is being pulled up or let down. The board allows for a LiPo battery and solar panel so that the motorized shade doesn't have to be connected to a power source. The board has a buck converter to boost the battery voltage to 12 volts for the motor.
