What computers or devices are compatible with the Code Kit?
To use the Code Kit, you'll need a computer with a USB port.
The Code Kit App is compatible with the following Operating Systems:
Mac 10.10 & above
Windows 7, 8 & 10
Chrome OS 50 & above
Ideally, you’ll have one computer for each Code Kit you want to use. You can operate multiple codeBits with one computer, but your students will have to take turns using the computer to upload their code from the littleBits Code Kit app to their invention.
UPDATE v1.1: Some users are reporting difficulties connecting to their codeBits with Mac 10.11 El Capitan and Mac 10.12 Sierra. If you see this behavior, try removing the latest version and downloading app version 1.0.8 here.
