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.
