Launched in 2016, the LEGO®
Education WeDo 2.0 Core Set (45300) contains 280 pieces, including a motor, and tilt sensor, and motion sensor. WeDo 2.0 features a programmable SmartHub that connects to a computer or tablet via Bluetooth Low Energy, meaning that there is no longer a need to physically tether creations to a computer (as was required with the original WeDo kit). The SmartHub is powered by either two AA batteries or a rechargeable battery pack (purchased separately).
