I've been tinkering with Arduino in its various offshoots and incarnations, over the past 15 years, and this little kit caught my eye, so I decided to give it a go. I really like the mix of sensors & outputs, which put this device almost on par with the Arduino Esplora, in terms of out-of-the-box usability. My only minor gripe is over the lack of an RGB led. Lessening the sting, somewhat, is the welcome inclusion of an OLED display. Especially nice is the fact that while all of the components are attached, as shipped, the board is preconfigured in a reasonable way that allows beginners to focus on coding, without worrying about learning electronics at the same time. I feel this would be an excellent courseware item for teaching entry level microcontrollers.ADDENDUM: New hobbyists should be warned that Grove-friendly sensors are often much more expensive than their generic Arduino counterparts. Even Grove cables are expensive enough that those needing more cables would get their best value out of purchasing another Grove Beginner's Kit.

For begginers, this board is good for whoever wants to focus on programming first and not physical connections

Very basic, great for getting started. Has everything you need to start in the box, including an Arduino-like board that is hooked up to sensors on one PCB. Just plug in to PC and start coding in Arduino IDE. (I use PlatformIO in VS Code.) Instructions on web-site are amateurish but clear. You can break out each sensor from the PCB by cutting it out and then use one of the cables in the kit to connect it to the MCU or your own Arduino board. Only gripe is the connectors are proprietary design and close but not equal to standard JST connectors. I guess this means you keep going back to them to buy cables and/or breakout boards for different Arduino-family or Raspberry Pi models. It will also work with Dupont style connectors although the connection isn't as perfect.

This is so so cool. I own dozens of Ardunio and Rasberry pi starter kits. By far the best starter kit. Maybe a dozen times 3 to be honest.

When I initially ordered it for my son, I ordered an Arduino to work with it, but once we got it, I realized it has an Arduino built in! Great kit to explore different interfaces with super easy connections.
