This handy, credit-card sized PCB is the perfect accessory for the amateur electrical engineer. On one side it has a beautiful eight-color silk screened resistor chart to help you identify resistors by their color (and finally beat Mho’s Resistance) and on the other there’s a comprehensive SMT reference with to-scale footprints for common SMT parts.
The best part of this PCB is how easy and fast it is to use. The colors are bright and the card’s clear and intuitive. And the back’s handy for anyone who has grown beyond through-hole soldering and is ready to take on surface mount.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
