6.2.2   Power System 

The power supply on the Debug Board is input from the USB Type-A Plug. A MB39C022G LDO is used to provide a 3.3-V 
output for each device. A supercapacitor (SC1) on the Solar BLE Sensor is charged via diode when the Solar BLE Sensor 
connects. The following is the block diagram for the power system.
