Protection Circuit
There is a diod transient voltage suppression diode (D12) which protects the board from reverse polarity, voltage spikes. Additionaly there is an Over/under voltage (IC) which protects the board from over voltage damagesovervoltage / undervoltage protection device (U9) for board protection.
