*A USB cord is included the Hummingbird Bit Robotics Kit with the purchase of a micro:bit. If you would like to program your robot wirelessly, you will need a BLE bluetooth dongle. You can connect via Bluetooth to up to three micro:bits or Hummingbirds, which means you can make larger projects.
**We support native Bluetooth for Macs equipped for Bluetooth 4.0. This includes all devices manufactured after 2014, and many devices from before that.
