Arduino-Compatible Due R3 clone built around the ATSAM3X8E ARM Cortex-M3 running at 84 MHz. A 32-bit step up from 8-bit boards for robotics, motion control, and embedded prototyping that needs more speed and memory.
Runs 3.3V logic and the I/O pins are NOT 5V tolerant. Use a level shifter for any 5V sensors or modules.

FAQ
Will this ship from Manila?
Yes — all stock ships from our Quezon City warehouse. Order before 4 PM weekdays for same-day cutoff via J&T or LBC.
Do you ship nationwide?
Yes. Metro Manila usually arrives next-day; provincial 1–3 working days.
Can I get this on a school PO or class order?
Yes — we accept Purchase Orders from accredited schools and universities. Contact us with your PO details and we'll process it.
Is this compatible with Arduino, ESP32, or Raspberry Pi?
Most parts work with common maker boards — check the description for specific pinout / voltage notes. If you're unsure, send us a message before ordering.
What's your return policy?
7-day inspection window for DOA units. Email proof of issue and we'll ship a replacement or refund. Used / installed parts are not returnable unless faulty.
Do you offer technical support?
Yes — questions land on our forum or via email, weekday or weekend. We've actually wired up most of what we sell.
