CrowPi2 advanced kit for Raspberry Pi 3 or 4 SBC. It contains all accessories, except the MicroSD card (the firmware image can be found on Github), and the Raspberry Pi is not included either and needs to be purchased separately. The kit can be used to teach electronics and programming to kids aged 8 years or older. I’ve only used it for about two weeks for evaluation, and it’s good as new.
