Figure 1: Full Diagram of a RISC-V AWS IoT Core Device Example
This demonstration shows a capacity of PSU (Power Supply Unit) for manage power for Marmot System by using Solar panel and battery. By monitor voltage on the Solar and Battery, PSU can decide resource of power supply will be use. In the case good sunshine, PSU use power from Solar to (1) Keep the system work as normal (2) Can charge for battery. Otherwise PSU can use power from battery.
