MicroPython pyboard v1.1

MicroPython pyboard v1.1 is a compact and powerful electronics development board that runs MicroPython. It connects to PC over USB, giving a USB flash drive on which to save the Python scripts, and a serial Python prompt (a REPL) for instant programming. With the MicroPython pyboard, gain a low-level Python operating system that able to use to control plenty of different electronics projects.The MicroPython 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. We have two options for the pyboard available: one with headers and one without.

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 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.
