README
Readme.mdPBSEQ-D2
PBSEQ-D2 is a simple push-button based power sequencer demo board designed in KiCad. You can press the push-button momentarily to turn on the output. Pressing again will turn off the output. A PMOS transistor is used as a high-side switch to control the power. An NMOS transistor controls the power sequencing. This demo project is fully open-source and you can find the source design files here.
A tutorial of designing and testing the circuit will soon be available at CIRCUITSTATE.

Questions
How big is the PBSEQ D2 PCB?
It measures 19 × 19 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PBSEQ D2 use?
22 parts, built around the 0603B104J500CT, WR06X1002FTL, WR06X1001FTL and WR06X2000FTL. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the PBSEQ D2 KiCad files?
From the CIRCUITSTATE/PBSEQ-D2 repository on GitHub, at the commit this page was made from: the board is PBSEQ-D2.kicad_pcb and its schematic PBSEQ-D2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PBSEQ D2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask CIRCUITSTATE before reusing the design.
