While the device looks good on paper, the build quality is appalling. I spent an hour figuring out why the I2C OLED screen didn't work until I realized the breadboard wires were shorting each other. To add insult to the injury, the documentation is scarce, referencing to a git repository that doesn't exist. An educational kit like this lives or dies by the documentation so in the current state I cannot recommend it. On the positive side, I'm very happy with the lego-like building blocks. They're fairly robust, and I would consider buying the building kit.
