Test 1
quick prototyp for using MPU9250 to get acc x, y values and gyro z values (change rate in deg/s !) to calculate present angle:
- 0° is upright
- -90° fall over foreward
- 90° fall over backwards

Questions
How big is the L6230driver PCB?
It measures 42 × 34 mm and has 2 copper layers, 1.6 mm thick.
What parts does the L6230driver use?
57 parts, built around the MCP6004T-I/SL(MS), L6230PD and 1N4148WT. 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 L6230driver KiCad files?
From the mwuerms/rollin repository on GitHub, at the commit this page was made from: the board is kicad/l6230driver/l6230driver.kicad_pcb and its schematic kicad/l6230driver/l6230driver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the L6230driver 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).
