CircuitPython has a number of “ports” that are the core implementations for different microcontroller families. Stability varies on a per-port basis. As of this release, these ports are consider stable:
atmel-samd: Microchip SAMD21, SAMx5x
cxd56: Sony Spresense
espressif: Espressif ESP32-S2
nrf: Nordic nRF52840, nRF52833
raspberrypi: Raspberry Pi RP2040
stm: ST STM32F4 chip family
These ports are considered alpha and will have bugs and missing functionality:
broadcom: Raspberry Pi boards such as RPi 4, RPi Zero 2W
espressif: ESP32, ESP32-S3, ESP32-C3
mimxrt10xx: NXP i.MX RT10xxx
stm: ST non-STM32F4 chip families

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.
