Seeed Grove Kit + BBC micro:bit Go
The Seeed Grove Kit comes with a book of 12 starter tutorials, with the 10 hardware modules provided. The BBC micro:bit Go/Essentials kit includes the micro:bit itself, USB cable, and plug-in battery pack to make your projects nice and portable. For primary-aged kids, there's no need to mess around with fiddly jumper cables or breadboards, and for parents/teachers it's easy to pack and go without worrying about disturbing ongoing projects.
This kit is great for those kids that already know a bit about coding but haven't yet ventured into programming hardware - where keyboard input is replaced by changes in light, movements, gestures or the turn of a dial. Rather than simply moving an object on a screen, kids can move on to turning on lights, digital displays, or sounds.
This combo includes the BBC micro:bit - which extends much further than this kit, allowing over 20 pins to integrate into other DIY electronics projects, kits and accessories. It even connects with Bluetooth, mobile devices, and to other micro:bits via radio.
