Solar Sense Board
The Solar Sense board monitors the current, voltage and temperature of each MPPT. It takes in SPI communications from each MPPT, regulates it, uses I2C ADCs to sense the voltage from each MPPT, regulates the I2C signal and then passes all of these communications to the controller board. It also runs accepts connections from thermistors running from each of the solar arrays.
The Solar Sense board is important because the car needs to keep track of voltage and temperature as well as communicate with the MPPTs to keep the car running optimally as well as prevent and respond to emergency conditions.
