Fittingly, it’s called the Ktuluino. Actually, this isn’t yet another attempt to build an Arduino clone that adds nothing to existing designs; it’s just [Jeff]’s attempt at PCB design.

The KIT_BTM9010/11 Arduino Shield (user manual here), which is currently available, comes equipped with the 10-A MOTIX full-bridge ICs BTM9010EP and BTM9011EP (Fig. 3).

In Part 1: Principles of Current Flow, we began with the basics. We learned that high-frequency signals flow not in the path of least resistance, but in the path of least impedance. We also discussed ...
