MIOTY Silicon Vendor Agnostic, Scalable LPWAN Standard to Take on LoRaWAN, NB-IoT

MIOTY

[April 6th update: The article was updated to reflect Fraunhofer invented the technology] There are plenty of LPWAN (Low Power Wide Area Networks) standards designed for low power, low bitrate and long-range connectivity with the most popular currently being NB-IoT and LoRaWAN. But Texas Instruments has joined other smaller companies (Fraunhofer, Ragsol, STACKFORCE, WIKA…) to form the MIOTY alliance in order to develop and promote a new LPWAN standard operating in the sub-GHz range called MIOTY. Texas Instruments explains MIOTY was born due to a lack of scalability and robustness (interferences issues) of current LPWAN solutions. But just like other similar low power WAN standards, it aims to support long-range while achieving long battery life, but MIOTY is also supposed to help IoT developers mitigate performance degradation in high-node-count networks. MIOTY works in the same license-free bands (868 MHz, 915 MHz …) as LoRa radios with no costs involved to […]

Rosetta@Home Now Supports 64-bit Arm SBC’s and Servers in the Fight against COVID-19

Roseatta@Home Arm Aarch64 Rock64

Folding@Home and Rosetta@Home projects aim to perform biomedical research using the computing power of volunteers. Basically, you just need to install a program on your computer, and it will use idle computing power to perform complex calculations without slowing down your computer as long as you are not short in RAM. The projects are now working on COVID-19 to understand how SARS-CoV-2 protein is structured which could help find a cure. The programs have been available for Windows, Linux and Mac OS on 32-bit and 64-bit x86 targets for years, but very recently Rosetta@Home has been made available for 64-bit ARM targets so people can also run BOINC program on Arm Linux SBCs such as Raspberry Pi 4, NVIDIA Jetson Nano, or Rock64, or even powerful Arm servers to help with Rosetta@Home project’s COVID-19 research. As explained in an article on miniNodes, you’ll need a board with at least 2GB […]

How to Build KiCad on Ubuntu 18.04 / 20.04 and Import Altium PCB Files

BeagleBone Black Altium KiCad

KiCad open-source EDA (Electronics Design Automation) suite software is now very popular, and many new projects are designed with the utility. AFAIK, some companies like Olimex switched all their new designs to KiCAD. But since many schematics and PCB layouts have been designed with other tools like EAGLE, Orcad Allegro, or Altium PCB design tools, it would be nice to be able to import those designs into KiCad. Converters have been around for a long time but when I tried to convert Beagleboard-xM OrCAD schematics to import them in KiCAD back in 2012, the results were really awful and unusable. But I recently saw a tweet saying it’s now possible to import Altium files into KiCAD. Finally, importing #altium boards into #kicad is only one click away (in the developer version). This allows to view and edit #opensource #hardware which was designed with #proprietary software, and thus, in fact, not […]

Widora TINY200 Allwinner F1C200s ARM9 Development Board Supports DVP Camera, Up to 512MB SD NAND Flash

Allwinner F1C200s ARM9 Development Board

Widora TINY200 is a tiny ARM9 development board equipped with Allwinner F1C200s with a DVP camera interface compatible with OV2640 / 5640 sensor, an audio amplifier, and various storage options from a 16MB SPI flash to a  512MB SD NAND flash. I first heard about the processor when I wrote about Microchip SAM9X60 ARM9 SoC last month, and some people noted there were other fairly new ARM9 SoCs around such as Allwinner F1C200s that also includes 64MB RAM so you can run Linux without having to connect external memory chips. Widora TINY200 V2 specifications: SoC – Allwinner F1C200s ARM926EJS processor @ 400-600 MHz (Overclockable to 900 MHz) with 64MB DDR1 RAM Storage – 16MB SPI NOR flash or 128MB NAND flash and MicroSD card slot or 512MB SD NAND flash. Display I/F – 40-pin RGB FPC cable for resistive touch screens; additional 6-pin FPC cable for capacitive touch support Camera […]

ESP32-S2-Saola-1 Development Board is Now Available for $8

ESP32-S2-Saola-1 Board

Espressif ESP32-S2 WiFi SoC mass production started at the end of February 2020,  and soon enough we started to find ESP32-S2 SoC and modules for $1 to $2 on sites like Digikey, but so far we had not seen ESP32-S2 development boards for sale. The good news is the breadboard-friendly ESP32-S2-Saola-1 development board has started to show up for $8 on resellers such as Mouser and Digikey albeit with a lead time of 8 to 12 weeks. ESP32-S2-Saola-1 specifications: Supported modules – ESP32-S2-WROOM(-I) & ESP32-S2-WROVER(-I) with 4 MB SPI flash and for ESP32-S2-WROVER modules only, 2 MB PSRAM USB – 1x Micro USB port for power and programming / debugging via USB-to-UART bridge Expansion – 2x 20-pin I/O headers with SPI, I2S, UART, I2C, touch sensors, PWM, etc… Misc – Boot and reset buttons, RGB LED, 3.3V power on LED Power Supply (3 methods) 5V via Micro USB port (default) […]

PinePhone “Community Edition: UBports” Linux Phone Launched with Ubuntu Touch

PinePhone Community Edition UBports

PinePhone “BraveHeat” Limited Edition Linux smartphone launched last November as promised for $149.99. As the codename implied, it was for the enthusiasts as the phones that were part of that product batch may have had some defects, and came without an operating system, meaning the users had to flash the firmware themselves. But there’s now a new edition, namely PinePhone “Community Edition: UBports” pre-loaded with UBports with Ubuntu Touch featuring Lomiri user interface. The specifications are exactly the same with an Allwinner A64 quad-core Cortex-A53 processor, 2GB RAM, 16GB eMMC flash, a 5.95″ display with 1440×720 resolution, and 4G LTE cellular connectivity. The only difference is that Ubuntu Touch is preloaded to the device, and the back of the phone should have a marking showing you purchased UBports Edition. What should be noted is that it’s still not considered as a consumer device, as UBports is still beta, and the […]
