What we like, and what to watch
What we like
- Lots of learning material. Kits come with free online tutorials and a forum, and kits like the Raphael Kit list 161 projects and 70+ video lessons, according to the brand.
- Free shipping with no minimum. The shipping policy lists free delivery to the US and most of Europe regardless of order size, with DHL or UPS used for orders over $400.
- Wide Raspberry Pi 5 range. Beyond kits, the store has Pironman cases with NVMe slots, touchscreens, UPS HATs and cooling made for the Raspberry Pi 5.
Watch out for
- Robot kits and cases do not include a Raspberry Pi, so the real cost is higher than the sticker price.
- Everything ships from China; standard US airmail is quoted at 7-14 working days, and import duties, if any, are on you.
- Return shipping is your cost unless the item is damaged or defective, and the return window is 15 days (the shipping page says 30, so confirm first).
- The refund policy does not state how long the warranty lasts, and opening, modifying or reflashing a product can void coverage.
Who should buy from SunFounder
SunFounder makes sense if you or your kids want to learn electronics and coding with a guided Raspberry Pi or Arduino kit, or you want an upgraded case for a Raspberry Pi 5. Plan for China shipping times and check whether you need to buy a Pi board separately.
SunFounder
Students, parents, teachers and hobbyists who want a guided Raspberry Pi or Arduino kit with lots of tutorials, or Raspberry Pi 5 owners looking for a feature-rich case.
