Questions
How big is the RocketTracker PCB?
It measures 27 × 35.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RocketTracker use?
58 parts, built around the ESP32-C3-WROOM-02-H4, TPS63070RNMR, MCP73871-1CCI/ML and USBLC6-2SC6. 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 RocketTracker KiCad files?
From the masakinumata/RocketTracker repository on GitHub, at the commit this page was made from: the board is hardware/RocketTracker/RocketTracker/RocketTracker.kicad_pcb and its schematic hardware/RocketTracker/RocketTracker/ESP32C3core.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RocketTracker design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
