Breadboard power supply with variable voltage output
This project is ideal for breadboard power supply so that different output voltages can be configured for other circuits.
The main power connector is USB type C, with which the PD fast charging protocol is implemented. The voltage output is provided by the header connectors J1, J2, J3, and J4.
With the Dip Switch SW1, you can configure the different supply voltages according to the configuration table of the CH224K integrated. Different voltages power the D1 indicator, so its brightness will vary depending on the voltage configured on the power supply.
