This clone acts just like an Arduino, and works with the latest Arduino software. For many projects it can even be preferable! The kit includes all parts necessary, the assembly is straightforward and well documented, using just a soldering iron anyone can complete it within 10 or 15 minutes. This version of the Boarduino does not have a DC jack. That means you cant use a 9V adapter or battery holder with it (unless you build a 5V power supply). it does have USB built in and you can power your project or USB or by using a Mintyboost kit (which takes 2 AA batteries)
Designed to plug into a breadboard for easy prototyping
Petite size, only 2.75″ x 0.8″ (75mm x 20mm)
All ‘standard’ pins are brought out – Digital 0-13, Analog 0-5, ARef, 5V, 3V, Ground, and Reset
Chip comes pre-programmed with a “no-wait” Arduino bootloader (Read more here)
4 LEDs! There’s a green power-good LED, a red “pin 13” LED (just like the Arduino), and a pair of RX and TX indicator LEDs for debugging the serial connection
Nearly-all-surfacemount design. We left the chip as through-hole to make it easier to upgrade and repair. All surface mount parts are pre-assembled and tested.
ATmega328P, running at 16.00 MHz, just like all Arduinos
6-pin standard ICSP header
USB miniB jack
500mA fuse protects your computer’s USB port from overcurrent
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
