    MicroPython May Be Powering Your Next Embedded Device
    MicroPython has announced that their pyboard D-series modules are now available.

    MicroPython has been an interesting project to watch over the last few years. If you’ve not heard of it, MicroPython is an open source project to port Python to run in a real-time, microcontroller-based environment. The ports typically are for ARM Cortex-M processors but there are several ports that run other architectures from Microchip Technology Inc. and other vendors. There are several advantages to using MicroPython over a traditional programming language like C such as:

    Easy to learn (I’ve seen elementary students write Python code)
    It is object-oriented.
    Is an interpreted scripting language which removes compilation
    Supported by a robust community including many add-on libraries which minimizes re-inventing the wheel
    Includes error handling (something that C didn’t get the memo on)
    Easily extensible

    The Pyboard D-Series Module

    As of this week, MicroPython has announced that their pyboard D-series modules are now available. These modules are particularly interesting because they provide a MicroPython compatible microcontroller along with built-in Wi-Fi and Bluetooth that can be connected to a carrier board through a mezzanine connector as shown below in Figure 1. This overcomes the challenges that developers face with using MicroPython in a production environment that forced them spin their own MicroPython compatible boards since the pyboard D-series is a module.

    The first is their standard model which utilizes a STM32F722 microcontroller from STMicroelectronics N.V. to provide 256k RAM and 512k of internal flash.

    The second option available is the pyboard D-series high-performance module. This module is based on the STM32F767, which provides 512k of RAM and 2MB of internal flash for application scripts.

    New Part Day: Pyboard D is Smaller, Wireless, and Has Expansion Modules

    Since the launch of pyboard and release of MicroPython source code, we’ve played with ports running on an ESP8266 and on a BBC micro:bit. The software ecosystem has continued to grow, most recently we looked at LittlevGL graphics library. But just because all the flashy action has been happening on the software side doesn’t mean the hardware side has been sitting stagnant.

    Pyboard-D upgraded from original pyboard’s STM32F4 to more capable STM32F7 chips. Witnessing the popularity of MicroPython on networked darlings ESP8266 and ESP32, there will be a pyboard D variant with a Murata 1DX on board for WiFi and Bluetooth connectivity.

    Hands-On: New Nvidia Jetson Nano is More Power In A Smaller Form Factor

    Today, Nvidia released their next generation of small but powerful modules for embedded AI. It’s the Nvidia Jetson Nano, and it’s smaller, cheaper, and more maker-friendly than anything they’ve put out before.

    The Jetson Nano follows the Jetson TX1, the TX2, and the Jetson AGX Xavier, all very capable platforms, but just out of reach in both physical size, price, and the cost of implementation for many product designers and nearly all hobbyist embedded enthusiasts.

    The Nvidia Jetson Nano Developers Kit clocks in at $99 USD, available right now

    A New Azure Sphere Development Board From Seeed Studio

    Last year Microsoft unveiled Azure Sphere — an end-to-end solution for securing micro-controller based smart things. Alongside the announcement was hardware support. With that announcement was the first official Azure development board built around the Mediatek MT3620 released by Seeed Studio, it cost $84.95.

    That price point was way out of line in a market that is highly price sensitive, and people are willing to make do with computing that is “good enough.”

    much cheaper version, the new MT3620 Mini Dev Board priced at a rather more reasonable $34.90.
