While it is a little pricey (~100 USD), there’s a lot to like about it. It comes with an LCD screen, plenty of pin breakouts, buttons, capsense pads and perhaps most relevant, a built-in ADC and DAC.
As an added bonus, the EFM32 PG12 includes an ARM Cortex M4 core with a dedicated floating point unit (FPU) that will speed up our computations. Using an ARM core also allows us to take advantage of the CMSIS DSP libraries that should give us an extra processing boost.
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.
