96Boards IoT Edition IVY5661 Board Features UniSoC UWP5661 WiFi 5 + Bluetooth 5 SoC

If you ever wanted to start a new IoT project with WiFi and Bluetooth connectivity, you’d like think about using Espressif ESP32 WiSoC that supports single band 802.11 b/g/n WiFi (WiFi 4) and Bluetooth 4.2 LE thanks to great community and software support on top of the ultra low cost of the solution. But in case your require 802.11ac (WiFI 5) – yes, I’m trying hard to get used to the new WiFi naming scheme for consumers -, or Bluetooth 5, Espressif Systems does not offer such solution yet. Instead you may consider UniSoC UWP5661 Arm Cortex-M4 WiSoC with WiFi 5 & Bluetooth 5 connectivity that will be found in the soon-to-be-launched UcRobotics IVY5661 96Boards IoT Edition board. I could not find lots of information about UWP5661 chip tself, so let’s jump directly to IVY5661 board specifications: SoC – UniSoC UWP5661 dual core Arm Cortex-M4 microcontroller @ 416 MHz manufactured with 28nm process Storage – 32Mbit NOR flash Connectivity (built-in …

Makerdiary nRF52840 Micro Development Kit Works with OpenThread, Arm Mbed OS, Zephyr OS, Mynewt, etc…

nRF52840 Micro Development Kit

If you want to play around with Bluetooth 5, Nordic nRF52840 is probably one of the best option, and among the development board, $9/$12 Particle Xenon is hard to beat when it comes to value. But if you need a bit more storage, I/Os and features, Makerdiary nRF52840 micro development kit looks like a good candidate to evaluate, especially it supports plenty of frameworks / operating systems such as Arm Mbed OS, Zephyr Project, OpenThread, Mynewt, and others. It’s also the first MCU class board I’ve seen with a USB type C port, although I’m not sure it brings any benefits to this type of hardware. Makerdiary nRF52840 micro development kit (nRF52840-MDK) hardware specifications: SoC – Nordic nRF52840 Arm Cortex-M4F WiSoC with 1 MB FLASH and 256 kB RAM, Arm TrustZone Cryptocell 310 security subsystem External Storage – 64-Mbit QSPI flash Wireless Connectivity (on-chip) Bluetooth 5, Bluetooth Mesh Thread, IEEE 802.15.4 ANT, 2.4GHz proprietary On-chip NFC-A tag On-board 2.4G chip …

My Attempt at Getting Started with Zephyr Project OS on ESP32

Zephyr Project is a real-time operating systems for the Internet of Things (IoT) that was introduced in early 2016, and supported/hosted by the Linux Foundation. It runs on a fairly large number of MCU boards from different architecture (x86, Arm, RISC-V, etc..), and Linaro even launched 96boards IoT compliant hardware like BLE Carbon board that are designed to run Zephyr Project. More recently, Linaro CEO revealed several commercial products are shipping with Zephyr Project OS, so I thought it might be a good time to give it a try. Target Board – Wemos Lolin32 I only had STM32 Bluepill, and some ESP32 boards, so I went with the latter since it comes with WiFi. But instead of re-using some of my existing boards, I asked Banggood whether they could send Wemos Lolin32, which they did. They sell it for $7.99 shipped, but any other ESP32 board should do. The board comes with two headers that you can solder if you …

Rigado Vesta IoT Gateway Runs Linux and Zephyr OS, Supports Bluetooth 5, 802.15.4, WiFi, Ethernet and Cellular Connectivity

I’ve recently read several open source software news related to Rigado IoT gateway, starting with Canonical announcement last month, that the gateway would ship with Ubuntu Core starting in summer 2018, and a few days ago it popped up again during Linaro CEO keynote at Linaro Connect HK 2018, as one of the first commercial devices to run the Zephyr OS, specifically its fully open source Bluetooth stack on a Nordic nRF52 chip. Rigado Vesta IoT gateway is not exactly new, as it was first announced in December 2016. The hardware relies on an NXP i.MX 6UL Cortex A7 processor, up to 256MB RAM, 4GB eMMC flash,  and includes built-in support for dual band WiFi, Bluetooth Smart, Bluetooth 5/4.2, 802.15.4 (Thread), Fast Ethernet with PoE, as well as optional support for a cellular LTE Cat 1 modem. Rigado gateway hardware specifications: Processor – NXP i.MX6 UltraLite (G3) Arm Cortex A7 processor @ 528MHz System Memory – 128MB or 256MB DDR3L …

RISC-V Keynote at Embedded Linux Conference 2018 (Video)

The Embedded Linux Conference and OpenIoT Summit 2018 have just started, and the Linux Foundation has already uploaded a few keynote videos to YouTube, including the one by Yunsup Lee, Co-Founder and CTO, SiFive, entitled “Designing the Next Billion Chips: How RISC-V is Revolutionizing Hardware”. Yunsup explains the current problem with chip development, and go through the open source RISC-V solutions offered by Sifive. Currently design a chip has a high upfront (NRE = non-recurring engineering) costs, is time-consuming (1.5 to 2 years at least) and silicon vendors normally target high volume production, but now many applications like IoT or machine learning require custom chips that may not be (yet) manufactured in such high volume. The solution is to adapt some idea from open source software to open source hardware in order to lower the costs, enable fast prototyping, and involve the community of designers and software developers. He took Instagram as an example, as it sold for $1 billion …

Embedded Linux Conference & IoT Summit 2018 Schedule

The Embedded Linux Conference 2018 and the OpenIoT Summit 2018 will jointly take place next month, on March 12 – 14, 2018 in Portland, Oregon, USA. The former is a “vendor-neutral technical conference for companies and developers using Linux in embedded products”, while the latter is a “technical conference for the developers and architects working on industrial IoT”. The Linux Foundation has already published the schedule, and it’s always useful to learn what will be discussed about even for people who won’t attend. With that in mind, here’s my own virtual schedule with some of the talks I find interesting / relevant to this blog. Monday, March 12 10:50 – 11:40 – Progress in the Embedded GPU Ecosystem by Robert Foss, Collabora Ltd. Ten years ago no one would have expected the embedded GPU ecosystem in Linux to be what it is now. Today, a large number of GPUs have Open Source support and for those that aren’t supported yet, …
