{"title":"Circuit Playground Express [Developer Edition]","handle":"circuit-playground-express-developer-edition","url":"/products/circuit-playground-express-developer-edition","description":"The Circuit Playground Express is an all-in-one development board packed with sensors, LEDs, and a speaker — all on a round, beginner-friendly PCB with alligator-clip pads. No soldering required. It supports four programming environments: Microsoft MakeCode (block/JavaScript), CircuitPython, Arduino IDE, and code.org CS Discoveries.\n\nPowered by an ATSAMD21 ARM Cortex-M0 processor at 48 MHz with 2 MB of SPI flash, the board plugs in via Micro-USB and shows up as a drive for easy drag-and-drop programming. It can also be powered by a AAA battery pack or LiPo battery.\n\nOnboard Features\n\n\n10× Mini NeoPixels – Individually addressable RGB LEDs\n\nMotion Sensor – LIS3DH triple-axis accelerometer with tap and free-fall detection\n\nTemperature Sensor – Thermistor for ambient readings\n\nLight Sensor – Phototransistor (also functions as colour and pulse sensor)\n\nSound Sensor – MEMS microphone\n\nMini Speaker – 7.5 mm magnetic speaker with Class D amplifier\n\nIR Transmitter &amp; Receiver – Remote control codes, inter-board messaging, proximity sensing\n\n2× Push Buttons – Labelled A and B\n1× Slide Switch\n\n8× Alligator-Clip I/O Pads – Analogue input, PWM output, I2C, UART\n\n7× Capacitive Touch Pads – Plus 1× true analogue output\nGreen Power LED &amp; Red #13 LED\nReset Button\n\n\nSpecifications\n\n\nProcessor – ATSAMD21 ARM Cortex-M0, 48 MHz, 3.3V\n\nFlash Storage – 2 MB SPI (for CircuitPython code and libraries)\n\nUSB – Micro-USB; acts as serial port, keyboard, mouse, joystick, or MIDI\n\nPower – USB, AAA battery pack, or LiPo battery\n\n\nIdeal For\n\nBeginners learning electronics and programming\nClassroom STEM activities (MakeCode and code.org)\nWearable and interactive projects (no soldering needed)\nCircuitPython and Arduino development\n\n\nResources\n\nCircuit Playground Express Guide\nGetting Started with MakeCode\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":13790,"title":"Default Title","sku":"AF-3333","price":53.19,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":103,"option1":"Default Title"}]}
