SiFive unveils Automotive E6-A, X280-A, and S7-A RISC-V processors

SiFive Automotive RISC V processor

RISC-V is coming to your car too, with the introduction of SiFive Automotive E6-A, X280-A, and S7-A RISC-V processors designed for automotive applications such as infotainment, cockpit, connectivity, ADAS, and electrification. Those are built on the existing SiFive Essential 6-series E6 32-bit real-time cores, SiFive Intelligence X280 64-bit RISC-V processor with AI extensions, and SiFive S7 64-bit real-time cores (equivalent to Cortex-R7/R8), but adds safety, security, and performance required by the automotive market such as ASIL compliance. Each new core targets specific applications within a vehicle: The SiFive E6-A series will be found in system control boards, hardware security modules (HSMs) and safety islands, as well as standalone in microcontrollers. The SiFive S7-A 64-bit  real-time core is said to be suited to the needs of SoCs with performant safety islands, requiring both low latency interrupt support and the same 64-bit memory space as the main application CPUs. The SiFive X280-A […]

Ortur LU2-10A 10W laser module issues and measuring laser power

Ortur LU2 10A laser module review

Karl here and I will keep this short for you. First I will share my experience installing an upgrade module for the Lasermaster 2 Pro, the Ortur LU2-10A. The LM2Pro came with a 5.5w laser module and this upgrade brings the power up to approximately 10w optical power. Spoiler, I am not happy with the kit. [Update (CNXSoft): The company has put us in direct contact with Ortur engineer, and they’ve promised to help us fix the issue. We’ll update the post if/once it is resolved] The Ortur LU2-10A kit comes with a very simple adapter board that appears to do two tasks. 1 is to adapt wiring, and 2, inject additional power for the higher power laser module. It looks like the board will adapt to a lot of different connection types. I followed the instructions and the first time I plugged everything in the laser came on full […]

SONOFF ZBMINI-L Zigbee 3.0 Smart Switch works without neutral wire

Sonoff Zigbee switch no neural wire

When using a wireless switch like SONOFF T2 a connection to the neutral wire is needed to power the device, but this is not always feasible/practical as many lights as cabled without a neutral wire. SONOFF ZBMINI-L Zigbee 3.0 smart switch solves this issue as it does not require a neutral wire. Simply connect the two wires for the light and you are good to go. ITEAD says its solution does not require an extra anti-flicker module and relies on an “advanced electricity extraction technique”. SONOFF ZBMINI-L specifications: Connectivity – Zigbee 3.0 via TI CC2652P, up to 50 meter range (line of sight) Input – 100-240V 50/60Hz up to 6A Output – 100-240V 50/60Hz up to 6A Max. Load Resistive – 1380W Max @ 230V, 720W Max @ 120V LED – 300W Max @ 230V, 150W Max @ 120V Dimensions – 54 x 45 x 24mm (supports 35mm DIN Rail […]

FOSDEM 2021 Online February 6-7 – Hardware, Embedded & IoT talks

FOSDEM 2021 Online

FOSDEM is an open-source developer event that takes place on the first week-end of February every year in Brussels, Belgium. Every year except this year, as due to COVID-19 restrictions, FOSDEM 2021 will take place online like most events these days. The schedule has been up for some time, and today I’ll look at some of the interesting talks mostly from the Embedded, Mobile and Automotive “virtual devroom” but also other tracks. Saturday, February 6, 2021 13:00 – 14:00 – From Reset Vector to Kernel – Navigating the ARM Matryoshka Long gone are the times of executing the OS in-place from memory-mapped flash upon reset. A modern SoC now comes with complex mask ROM firmware, with driver, filesystem, protocol and crypto support for loading… yet another bootloader. In his talk, Ahmad follows this chain of bootloaders until the kernel is started, stopping along the way for RAM setup, peripherial initialization, […]

Intel Elkhart Lake COM’s offer up to 3x 2.5GbE, SIL2 functional safety

Elkhart Lake COM Express 2.5GbE

Since the launch of the Intel Elkhart Lake IoT Edge processor family, we’ve covered several COM Express modules based on the new low power SoCs including TQ Embedded TQMxE40C1/C2 and Congatec conga-MA7 & conga-TCA7. But despite the processor supporting 2.5GbE, all the computers-on-module we’ve covered so far would only offer Gigabit Ethernet connectivity. But Eurotech CPU-161-19 and CPU-161-20 COM Express Compact Type 6 modules support up to three 2.5 Gbps Ethernet interfaces using COM Express with proprietary expansions, and CPU-161-20 is the first module we’ve seen taking advantage of Intel Atom x6000FE parts with Functional Safety (FuSa)  support making the module certifiable with SIL2 Safety Integrity Level (IEC 61508-2:2010) and/or Cat 3 PL=d (ISO 13849-1). As we may infer from the photos above and below, both modules share many of the same features, except for the added functional safety on CPU-161-20. CPU-161-19/20 specifications: SoC CPU-161-19 module Atom x6212RE dual-core processor @ […]

UL-Certified TP-Link Kasa Smart Plug with Dual Outlet Sells for $19.99 (Promo)

UL-Certified Smart Plug TP-Link Kasa

WiFi smart sockets to control home appliances have been around for a few years, and one of my favorite companies is Sonoff as they offer a variety of affordable smart plugs pre-loaded with eWelink firmware and compatible with open-source firmware like Tasmota and ESPurna. The company is also attentive to safety. communicate issues with customers, and recently wrote a post entitled “Safety is our responsibility” where they detail all steps taken to make sure their mains connected device sare safe to use. Sadly that does not include safety certifications like UL/ETL, or TUV which may have implications for your home insurance depending on where you live, and for peace of mind, it’s always good to have a third verify your design for safety. Which brings me to the main point of this point, as a UL-certified dual-outlet smart socket, namely TP-Link Kasa Smart Plug, is currently on sale for $19.99 […]
