Questions
How big is the ESP32-Sequencer v0.2 PCB?
It measures 152.4 × 94 mm and has 6 copper layers, 1.6 mm thick.
What parts does the ESP32-Sequencer v0.2 use?
125 parts, built around the ESP32-S3-DEVKITC-1-N8, ADS1115IDGS, TPS5430DDAR and MMBT2222A. 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 ESP32-Sequencer v0.2 KiCad files?
From the brokebit/PA-Sequencer-Hardware repository on GitHub, at the commit this page was made from: the board is ESP32-Sequencer-v0.2.kicad_pcb and its schematic Buttons.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32-Sequencer v0.2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask brokebit before reusing the design.
