@Shrigglepuss @bonkers Just in case Microbit isn't what @fluffy was looking for: honestly, if it's just one device and that you can't find elsewhere and it's for a good cause, don't feel bad to buy from them once. We're not those who make the rules, avoiding questionable or even outright bad actors isn't always possible.
The more your niece learns about tech the more knowledgeable she is to identify bad actors herself later. Exceptions confirm the rule, and this would be a reasonable one. π
@Natanox @Shrigglepuss @fluffy if the kid has no prior programming experience, RPi will be an overkill that will also be difficult to use. Microbit is designed for kids specifically. You just connect it and start coding in scratch, JavaScript or python, straight from the browser. Also, a ton of third party add-ons, like robot cars or servos.
