In your journey hacking, modding and making electronics you will bump into many a FLASH chip. Often times these store program memory, settings, data files etc. Some microcontrollers have built-in flash, but an external flash chip allows for field-updating. Also, fitting a large Flash chip inside a micro or FPGA can increase cost a lot, where-as having it be external lets the customer pick exactly the right size they need. They can range from 256 bytes up to 16 MBytes or even more!
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.
