FAQ
Which Arduino should I buy first?
The UNO R3 or R4 WiFi is best for beginners. It’s compatible with most shields and lessons online.
Are these original or compatible boards?
Both are available. Originals come from Arduino.cc; compatible versions provide the same pinout and IDE support at lower cost.
Can I use the Arduino IDE on Mac or Linux?
Yes, the Arduino IDE runs on Windows, macOS, and Linux. You can also use the Arduino Web Editor.
Do you ship nationwide?
Yes — fast shipping anywhere in the Philippines. Same-day processing on in-stock orders before cutoff.
