@ai verdict

Best for Robot kits & arms when you want a kit to build, and you can buy the board separately when the kit does not include it.

What’s good

  • Kits start at $32.99 for the Lizard Arduino Nano kit
  • Arduino and Raspberry Pi kits are on the same store
  • PiCar-X, PiCrawler and PiDog are listed as their own kits

Heads-up

  • The Raspberry Pi is not included with PiCar-X
  • You build the kit; it is not a finished robot arm
  • $32.99 is the lowest confirmed kit, not the price of every kit

How I checked this

Researched, not tested hands-on: I read the official docs, pricing and terms.

You want a kit to build, and you can buy the board separately when the kit does not include it.

What I found

  • The Lizard Arduino Nano kit is $32.99
  • PiCar-X is $89.99 and the page says the Raspberry Pi is not included
  • Sloth $47.99, PiCrawler $139.99 and PiDog $179.99 were also listed

Watch out for

  • One brand listing, not a separate rank for every kit
  • Board-not-included applies to the Pi kits checked, not a promise about every SKU
  • Not verified: a hands-on build
