FAQ
Are these Pololu items compatible with Arduino and Raspberry Pi?
Yes—Pololu carriers expose standard pins and include documentation. Most work with Arduino, micro:bit, and Raspberry Pi via I²C/SPI/UART or GPIO.
Do you have QTR line sensor guides?
Check our Learning hub for line-follower projects and QTR calibration tips. You can also search “QTR” for available models.
Which stepper driver should I pick?
Start with DRV8825 for most NEMA 17s (1–1.5A). Move to TB67S/TMC for smoother motion and better thermals. See the quick guide above.
Do you ship nationwide?
Yes. We ship anywhere in the Philippines. Same-day processing on in-stock orders before cutoff.
