The Crow Pyboard is a powerful electronics development board which runs MicroPython. Connecting it to your PC via USB, and giving you a USB flash drive on which to save your Python scripts, and a serial Python prompt for instant programming. With the Crow Pyboard you gain a low-level Python operating system that you are able to use to control plenty of different electronics projects.
At its heart, the Crow Pyboard possesses a STM32F405RG microcontroller with a 168 MHz Cortex M4 CPU, 1024KiB flash ROM, and 192KiB of RAM. Each pyboard is also equipped with a microUSB connector for power and serial communications, a microSD card slot, an MMA7660 3-axis accelerometer, 31 GPIO, four LEDs, a reset switch and a user switch.
MicroPython is a complete rewrite of the Python (version 3.4) programming language so that it fits and runs on a microcontroller. It includes many optimizations so that it runs efficiently and uses very little RAM. Additionally, MicroPython runs bare-metal on the pyboard, and essentially gives you a Python operating system. The built-in pyboard module contains functions and classes to control the peripherals available on the board, such as UART, I2C, SPI, ADC and DAC.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
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.
