Pi-oT Raspberry Pi Add-on Board Targets Commercial & Industrial IoT Automation (Crowdfunding)

USA Based Startup Builds RPi Add-on Pi-oT, a Cleveland based startup has launched a Kickstarter campaign for a Raspberry Pi add-on for commercial and industrial IoT automation. The unit is a full mountable chassis with fan and DIN-rail that extends the Pi’s GPIO with 26-pin terminal connectors and provides 5x relays, 8x ADCs, and power outputs. We have reported on a variety of uses for the Raspberry Pi SBC, from home automation to development in IoT, to hobby projects, and in education settings. It is not surprising to see an automation module developed for IoT industrial applications around the popular and powerful SBC. The Choices The Kickstarter campaign has passed its low initial target and is set to ship at the end of October. There is an early launch discount on the unit’s price of $40 for commercial and $50 for industrial backers. That early bird type special is 15% […]

Microsoft to Support exFAT File System in Linux, Releases exFAT Specification

Microsoft’s exFAT file system is quite popular for removable mass storage devices such as SD cards and USB flash drives as it’s supported in Windows, and many consumers devices such as cameras can handle Microsoft’s patented file system. The “patent” part causes an issue in Linux, as companies need to license it in order to ship it in their products or operating systems image. I recently re-installed Ubuntu 18.04 on my laptop, and if I reinsert my “test” USB drive: BTRFS, EXT-4, and NTFS partitions all mount automatically, but not the exFAT one. If I click on the partition, I get this message: That’s because Canonical does not provide exFAT by default in Ubuntu due to legal issues. It’s however easy enough for the user to install exFAT utilities

sudo apt install exfat-fuse exfat-utils

1	sudo apt install exfat-fuse exfat-utils

The drive will mount successfully:

 mount | grep -i exfat
/dev/sdc3 on /media/jaufranc/USB3_EXFAT type fuseblk (rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096,uhelper=udisks2)

1 2	mount \| grep -i exfat /dev/sdc3 on /media/jaufranc/USB3_EXFAT type fuseblk (rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096,uhelper=udisks2)

Note that it’s using FUSE (Filesystem in Userspace), and it’s usually not a problem […]

Using Sony PS3 Eye Camera as an Inexpensive Microphone Array

Almost exactly two years ago to the day, we published an article showing how microphone arrays performed against a single USB microphone, and the latter started to have a poor wake word detection success rate at around 3 meters array even in a silent room, and it got worse with white noise or background music, while the microphone arrays would pick up the wake word with a much higher success rate in all conditions. The price of smart audio development kits varies a lot from $500 for Intel Speech Enabling Developer Kit to $129 for an Allwinner R18-based 3-Mic Far-Field Amazon AVS Development Kit, and $99 for ReSpeaker Core v2. If you’ve already got a Raspberry Pi 3/4 board, you can get cheaper options such as ReSpeaker 4-Mic Array for $25, but nothing beats the price of Sony PS3 Eye camera that comes with a 4 microphone array and sells […]

$5 Longan Nano GD32V RISC-V Development Board Comes with LCD Display and Enclosure

There’s been some exciting news about RISC-V microcontrollers recently with Gigadevice announcing GD32V, one of the first RISC-V general-purpose microcontrollers, which outperforms its Arm Cortex-M3 equivalent in terms of performance and power consumption. The company also announced some development boards, but they are not quite that easy to purchase being listed on Tmall website in China. The good news is that Sipeed has introduced Longan Nano development board powered by GD32VF103CBT6 microcontroller, and it’s up for sale on Seeed Studio for $4.9. Longan Nano board specifications: MCU – Gigadevice GD32VF103CBT6 32-bit RISC-V (rv32imac) microcontroller @ 108 MHz with 128KB Flash, 32KB SRAM Storage – MicroSD card slot Display – 0.96″ 160×80 IPS RGB LCD connected via SPI USB – 1x USB Type-C port for power and programming Expansion – 2x 16 through holes (2.54mm pitch) exposing 3x USART, 2x I2C, 3x SPI, 2x I2S, 2x CAN, 1x USBFS (OTG), 2x […]

AndesCore N22 RISC-V Core Supports RV32IMAC or RV32EMAC Instruction Sets

We covered Gigadevice GD32V general-purpose microcontroller with a RISC-V “Bumblebee” core last week, and I was informed that Andes Technology had recently introduced AndesCore N22 RISC-V “Bumblebee” IP core capable of supporting either RV32IMAC or RV32EMAC instruction sets. A web search did not reveal any specific information about what “Bumblebee” RISC-V cores are exactly, or maybe it’s in reference that many can be coupled in parallel. But that’s just a small detail, let’s check out in some details what AndesCore N22 core has to offer. The RISC-V core is designed for entry-level MCUs found in IoT devices and wearables, and is capable of deeply embedded protocol processing for I/O control, storage, networking, AI and AR/VR. Highlights of AndesCore N22: AndeStar V5 (RV32IMAC) / V5e (RV32EMAC) Instruction Set Architecture (ISA), compliant to RISC-V technology plus Andes extensions architectured for performance and functionality enhancements 32-bit, 2-stage pipeline CPU architecture 16/32-bit mixable instruction […]

Nordic Thingy:91 Cellular IoT Prototyping Platform Comes with 16 Sensors

Nordic Semiconductor launched the Nordic Thingy:52 back in mid-2017 in the hopes of bringing app and web developers into the hardware ecosystem as fast and easy as possible. The Nordic Thingy:52 was a Bluetooth 5 IoT sensor development kit based on the company’s nRF52832 WiSoC. Although the Nordic Thingy:52 kit is still very much available for purchase and support always available, Nordic Semiconductor has gone further launching a new development kit called the Nordic Thingy:91 targeting cellular IoT applications. The Nordic Thingy:91 is a cellular IoT prototyping platform with support for LTE-M, NB-IoT plus GPS option. Even though IoT connectivity standards like LoRaWAN, BLE, WiFi, ZigBee, and others are very much growing and expanding, Nordic Semi is fully backing cellular technology, something that has very much been available and most likely will still keep been available, and the adoption of 5G is another testimony to that. Cellular is here, and […]

Fairphone 3 Socially Responsible Android Smartphone Launched for 450 Euros

Most phones today are disposable items, and if yours stops working for whatever reason it’s hard to repair it yourself work, and repairing it at the shop may prove to be too expensive. They are not really expandable either, so if you want a new feature, you may have to buy a completely new phone instead of simply adding a module with the functionality. The difficulty in repairing the phone and the lack of modularity leading to electronics waste. Finally, consumer products are cost-optimized, and that’s great for your wallet, but it may come at the cost of being made by slave labor either directly at the factory, or indirectly through the mining of materials. Aren’t you already feeling bad being complicit in destroying the planet and sponsoring human suffering while reading this on your device? Good! But luckily there’s a solution with Fairphone that aims to be an ethical […]
