Circuit Playground Bluefruit - Bluetooth Low Energy Bluetooth * Antenna Type: Antenna NotCircuit Playground Bluefruit is our third board in the Circuit Playground series, another step towards a perfect introduction to electronics and programming. We've taken the popular Circuit Playground Express and made it even better! Now the main chip is an nRF52840 microcontroller which is not only more powerful, but also comes with Bluetooth Low Energy support for wireless connectivity. The board is round and has alligator clip pads around it so you
