ESP32-Ethernet-Kit, an Ethernet-to-Wi-Fi development board based on ESP32

The ESP32-Ethernet-Kitis  is an ESP32-based Ethernet-to-Wi-Fi development board that enables Ethernet devices to be interconnected over Wi-Fi. At the same time, to provide more flexible power supply options, the ESP32-Ethernet-Kit also supports power over Ethernet (PoE).

It consists of two development boards, the Ethernet board A and the PoE board B. The Ethernet board (A)contains Bluetooth / Wi-Fi dual-mode ESP32-WROVER-B module and IP101GRI, a Single Port 10/100 Fast Ethernet Transceiver (PHY). The PoE board (B)provides power over Ethernet functionality. The A board can work independently, without the board B installed.

Install Python 3.7 (and IDLE3) on Ubuntu 19.10

This post show how to install Python 3.7 and IDLE (the integrated development environment for Python) on Ubuntu 19.10. Tested on VirtualBox running over Windows 10.

By default, Python 3 is installed on Ubuntu 19.10, currently Python 3.7.5rc1. You can run the command to install it if it's not installed:
$ sudo apt install python3

To run Python 3, simple enter the command:
$ python3

But IDLE is not installed by default. To install it, enter the command:
$ sudo apt install idle3

or

$ sudo apt-get install idle3

After installed, you can run IDLE with the command:
$ idle

TensorFlow Lite for Microcontrollers

TensorFlow Lite for Microcontrollers is an experimental port of TensorFlow Lite aimed at microcontrollers and other devices with only kilobytes of memory.

It is designed to be portable even to "bare metal" systems, so it doesn't require operating system support, any standard C or C++ libraries, or dynamic memory allocation. The core runtime fits in 16KB on a Cortex M3, and with enough operators to run a speech keyword detection model, takes up a total of 22KB.

Google introducing new Cloud IoT Device SDK for embedded IoT devices to connect to Google Cloud IoT Core

Google, in collaboration with silicon partners, are introducing a new Cloud IoT Device SDK.

The partners include:

• Arm
• Cypress Semiconductor
• Nordic Semiconductor
• Espressif Systems
• Microchip
• NXP

The Cloud IoT Device SDK consists of client libraries written in Embedded C that enable developers to securely connect, provision, and manage devices with Cloud IoT Core. The kit targets energy- and size-constrained applications, such as battery-powered cellular devices that act as asset trackers, or Wi-Fi smart home devices with limited flash ROM (read-only memory).

In addition to partner platforms that are supported out of the gate, now you or your embedded systems engineering team can easily port the Cloud IoT Device SDK to a wide array of 32-bit microcontrollers (MCUs) and across various real-time operating systems such as Zephyr, ARM Mbed OS, FreeRTOS kernel, with more to come. The SDK also operates on POSIX-compliant operating systems like Linux, and can scale down to bare metal devices with the inclusion of its asynchronous API and event scheduler.

Microchip introduces new development board for Google Cloud IoT Core

Microchip Technology Inc. (Nasdaq: MCHP) announced a new Internet of Things (IoT) rapid development board for Google Cloud IoT Core that combines a low-power PIC® microcontroller (MCU), CryptoAuthentication™ secure element IC and fully certified Wi-Fi® network controller. The solution provides a simple way to connect and secure PIC MCU-based applications, removing the added time, cost and security vulnerabilities that come with large software frameworks and Real Time Operating Systems (RTOS). Once connected, Google Cloud IoT Core provides powerful data and analytics to help designers make better, smarter products.

Machine learning models + IoT data = a smarter world

With the IoT market set to triple in size by 2020, and massive increases in computing power on small devices, the intersection of IoT and machine learning is a trend that all developers should pay attention to. This talk will cover three core use cases, including: how to manage sourcing data from IoT devices to drive machine-learned models; how to deploy and use trained models on mobile devices; and how to do on-device training with a Raspberry Pi computer.
