A system comprising a power source, a RASPBERRY PI Hardware Attached on Top (RPI HAT) with an Uninterruptable Power Supply (UPS), and a RASPBERRY PI (RPI) is provided. The power source provides power to the RPI via the RPI HAT. The RPI HAT comprises a super-capacitor (SC) back-up system comprising an SC power bank and compatibility circuitry configured to charge the SC power bank to a sufficient level such that the SC power bank is usable as a back-up power supply in response to the loss of power from the power source. The SC back-up system is electrically coupled to the power source such that the power source is capable of charging the SC power bank and the SC power bank discharges and provides power to the RPI in response to a loss of power from the power source to the RPI.
