The tactile button spot is a nice touch too, making calibration a one-thumb job. Took me about an

After messing up a couple of breadboard prototypes, having this PCB made the EDTracker build so much cleaner. The breakout for the MPU-9250 is really handy, and the tactile button placement feels intuitive for calibration.
