Regulator
About the Regulator PCB
Regulator is an open source PCB design by shelxty, published on GitHub. It is a 2-layer board measuring 28.4 × 9.4 mm, with 10 components from 9 distinct parts.
Other key parts include the TPS79333DBVR. By type, the board carries 3 capacitors, 2 connectors, 2 diodes, 2 resistors and 1 IC.
From the project
Simple regulator PCB that converts a volatile 3.4 to 5V input to a stable 3.3V output; contains 2 LEDs that indicate when inputs are received and outputs are successful.
After a lot of struggle with attempting to understand KiCad (thank you Hack Club Fallout mentors!) I made a simple linear voltage regulator to get started with learning, since this was a project simple enough to actually understand completely (schematic, PCB, everything). It's the first PCB I fully finished, designed in KiCad. I guess it can also be counted as my first actual electronics project!

Regulator: common questions
How big is the Regulator PCB?
The Regulator measures 28.4 × 9.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Regulator?
10 components, from 9 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Regulator design files?
From the shelxty/regulator_pcb repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Regulator design in my own project?
The repository has no license, so all rights stay with shelxty. Use it as a reference, and ask the author before reusing the design.
