From the project
Complete KiCad PCB design of a 5V to 3.3V linear voltage regulator using AMS1117-3.3, with schematic, two-layer PCB layout, routing, and 0 DRC violations.
A compact 5V to 3.3V linear voltage regulator board designed in KiCad 10 using the AMS1117-3.3 regulator. The board accepts 5V input through a Micro-USB connector and provides a regulated 3.3V output through a 2-pin screw terminal. The board accepts 5V input through a Micro-USB connector and provides a regulated 3.3V output through a 2-pin screw terminal.
The board converts a 5V input supply to a regulated 3.3V output using the AMS1117-3.3 linear voltage regulator. The design includes input and output filtering capacitors to improve supply stability and reduce voltage fluctuations.
