Received tiny 3.3V stepper motor with embedded TMC2300 driver from Kade Turner today 👏

Together with this tiny TMC2300 breakout board. Both boards are extremely cool and well done!

Pendant qu'on est dans la soudure, quelques images qui montrent bien les phénomènes de mouillage et de capillarité lors de la soudure.

Testing out the tiny actuator. Not as strong as I thought but smooth and silent! 👋 Kade Turner

Ever wanted to debug your microcontroller over USB-C? (I'm talking JTAG/SWD, not just USB!) If you already have a USB-C connector, there's no need to have an additional connector to program (or tag-connect pads, which are super nice) Here's one way to do it: 🧵

If you want to analyze the DC drop of a simple power delivery polygon you can do so in 2D with the freeware tool FEMM. You can import the DXF contour of the polygon you want to analyze and assign fixed voltages and load currents.
