![]() 7 input pads acting as capacitive touch inputs.ġ input pads acting as analog output (True analog output).8x input/output pins compatible with alligator-clip.Made with one phototransistor, a transistor conducting current when it is excited by the light.īased on microphone capturing sounds (or tap) all around.Ī 7.5mm magnetic speaker/buzzer + audio amplifier (class D)Ĭan transmit any remote IR control codes or receive IR signals.Īllows to send messages between Circuit Playground Expresses and can also act as proximity sensor. (a triple-axis accelerometer that can be used for tap detection, sock detection, fall detection, thanks to A LIS3DH)Ī thermistor where the internal resistor varies with the temperature. 10x NeoPixels (each one can display a different color).Some features and interface of the board: You just need a Web Brower and a free USB (or text editor) and you are ready to go! It is a great and simple way to program a board, no need for compiler or specific software on the computer. Once the CircuitPlayground Express plugged on the computer, it show itself as an USB flash drive (easy to transfert MakeCode and CircuitPython program to the board). The CircuitPlayground can be powered from USB, AAA battery pack or Lipoly accumulator (experimented users). Wearable addicted can also sew the connections with conductive wire. The board is round offers alligator clips holes for quick and easy connexion (no need to solder for experiment electronics). So it is a great board for learning and experimenting from beginner level to expert level, Circuit Playground Express has something to offer to everyone.ĬPX is design to be easy to use, even for beginner. ![]() It would alsso allow a significant saving while learning (we can learn 4 times with the same material). You can check the Adafruit starter guide which details the Circuit Playground Express plateform and getting started with MakeCode, CircuitPython, CS Discoveries ( ) or Arduino!Ĥ programming languages to program the same board is great to re-use the material in different way. It is also possible to use the CS Discoveries from to learn coding from you WebBrowser! Arduino IDE, allows to program the board at the low level and being able to create really powerful project. Advanced user will also appreaciate to try the Arduino IDE environment to program the board in C. But the board can also be programmed with CircuitPython (a MicroPython based interpreter running on board). The user can start discovery with MakeCode (MicroSoft), a block based (or Javascript) programming environment. This board is based on the polupar Adafruit Circuit Playground Classic board (which is Arduino Compatible only) but modified to make it simplier to program while sitll adding more sensor. Circuit Playground Express, it is like the Micro:bit but with other sensors, other user interface and other possibilitiesĬircuit Playground Express (CPX) will be a step forward to discover the programming and electronic.
