Circuit Playground Express is a perfect introduction to electronics and

programming. It combines a poweful ATSAMD21G18 microcontroller with full

Code.org CS Discoveries, MakeCode, CircuitPython and Arduino support. You

can program it in any of those language and it even comes with a collection of

useful sensors, inputs and outputs all built-in! The board is round and has

alligator-clip pads around it so you don't have to solder or sew to make it work.

You can power it from USB like your computer. To make it portable, a AAA

battery pack, or with a Lipoly battery (for advanced users) can be plugged in.

Circuit Playground Express has built-in USB support. Built in USB means you

plug it in to program it and it just shows up, no special cable or adapter

required. Just program your code into the board then take it on the go!

This pack is for educators who wish to purchase Circuit Playground

Express development boards in bulk along with accessories for getting

started. You'll get enough parts for 15 students working individually or 30

students working paired up. All at a price that makes it possible to give anyone

a chance to explore, perfect for classrooms and workshops!

In particular, this pack is for instructors teaching the physical computing unit of

the Code.org CS Discoveries curriculum, but it can also be used by any

instructor who is teaching with MakeCode, Arduino or CircuitPython

Pack includes:



15 x Circuit Playground Express - Programmed with Firmata so it can be
