MicroPython pyboard v1.1 (with Headers)

The pyboard is a compact and powerful electronics development board that runs MicroPython. It connects to your PC over USB, giving you a USB flash drive on which to save your Python scripts, and a serial Python prompt (a REPL) for instant programming. With the MicroPython pyboard you gain a low-level Python operating system that you are able to use to control plenty of different electronics projects.

This board comes with headers soldered, as in the pictures above. The header pins are the HDR-PD8 product and are female with 56 total positions. These headers are compatible with standard 0.65mm square male pins (Arduino style).

At its heart, 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: 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 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.

Pyboard Hookup Guide

September 7, 2017

Getting started with the Pyboard using MicroPython.

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

2 Programming

Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Very powerful board

Having Micropython as the operating system eliminates much of the overhead of having a Linux system. The clock speed is a little slow for some complex tasks, but the MicroPython makes it much easier to do complex tasks than bare-metal programming.

Great for testing hard to access chips

For testing various chips, especially ones with weird I2C registers, or other protocols that may be out of the mainstream, this board is great. And the python code that you develop for the problem chips is easily ported to C or anything for embedded work.

Great MicroPython Board

The Pyboard makes using MicroPython very easy.
