STMicro releases IO-Link actuator board for industrial monitoring and home appliances

STMicro EVLIOL4LSV1 IO-Link actuator board

STMicro has announced the EVLIOL4LSV1 IO-Link actuator board, an STM32G071CB Cortex-M0+ MCU-based reference design for commercial manufacturers with a built-in protocol stack and application software. Aimed at industrial beacons and home-appliance alarms, the EVLIOL4LSV1 combines the L6364Q dual-channel IO-Link transceiver (communications) and IPS4260L intelligent low-side power switch (for driving industrial loads). The EVLIOL4LSV1 IO-Link actuator board is powered by an STM32G071CB Arm-Cortex-M0+ microcontroller that hosts the proprietary stack and application software and communicates with the transceiver and low-side power switch. The evaluation board can be used to test the IPS4260 and L6364Q ICs. It features a 4-pin M12 connector for an IO-LINK master and a 5-pin SWD connector for programming. It can also directly interface with signaling systems, ranging from smart tower lights in factory automation to funnel alarms for quantity monitoring. The onboard transceiver is protected against electromagnetic interference and supports COM2 and COM3 speeds. It offers multiple modes […]

Getting Started with Raspberry Pi AI HAT+ (26 TOPS) and Raspberry Pi AI camera

Raspberry Pi AI HAT+ and AI camera review

Raspberry Pi recently launched several AI products including the Raspberry Pi AI HAT+ for the Pi 5 with 13 TOPS or 26 TOPS of performance and the less powerful Raspberry Pi AI camera suitable for all Raspberry Pi SBC with a MIPI CSI connector. The company sent me samples of the AI HAT+ (26 TOPS) and the AI camera for review, as well as other accessories such as the Raspberry Pi Touch Display 2 and Raspberry Pi Bumper, so I’ll report my experience getting started mostly following the documentation for the AI HAT+ and AI camera. Hardware used for testing In this tutorial/review, I’ll use a Raspberry Pi 5 with the AI HAT+ and a Raspberry Pi Camera Module 3, while I’ll connect the AI camera to a Raspberry Pi 4. I also plan to use one of the boards with the new Touch Display 2. Let’s go through a […]

Beelink EQ14 mini PC features Intel N150 quad-core “Twin Lake” processor, built-in power supply

Last month we noted the Intel Processor N150, Processor N250, and Core i3-N355 Alder Lake-N Refresh CPUs were found in the upcoming ASUS NUC 14 Essential mini PC family, but availability was unclear. The Beelink EQ14 is the first Intel N150 mini PC which can be purchased today on either AliExpress (with EU plug) or Amazon for $182 and up for Black Friday and Cyber Monday 2024. Beelink calls the CPU family “Twin Lake” instead of “Alder Lake-N Refresh”, but we can’t confirm that since the N150 has not been officially launched yet and it’s not listed on Intel Ark. The computer is equipped with 16GB DDR4 memory, a 512GB NVMe SSD, two HDMI ports, two gigabit Ethernet ports, WiFi 6, etc… It also comes with a more unusual feature: a built-in AC power supply, something we previously saw in the Beelink EQ13 with an Intel N200/N100 CPU. Beelink EQ14 […]

$7 Raspberry Pi Pico 2 W board launched with 2.4 GHz WiFi 4 and Bluetooth 5.2 wireless module

As expected, the Raspberry Pi Pico 2 W – the wireless version of the Raspberry Pi Pico 2 – is now available with an extra 2.4GHz WiFi 4 and Bluetooth 5.2 wireless module at an official price of $7. We’ll go through the specs and perform a mini review in this post trying out both WiFi and Bluetooth code samples. It’s not the first Raspberry Pi RP2350 with WiFi and Bluetooth we’ve seen, as Pimoroni introduced the Pico Plus 2 W board with an RP2350B MCU and Raspberry Pi RM2 Wi-Fi and Bluetooth module, and iLabs launched the Challenger+ RP2350 WiFi6/BLE5 board relying on ESP32-C6 wireless module. However, the Raspberry Pi Pico 2 W is the official board, is cheaper, and will certainly be the most popular/widely used. Raspberry Pi Pico 2 W specifications Raspberry Pi Pico 2 W specifications: SoC – Raspberry Pi RP2350 CPU Dual-core Arm Cortex-M33 @ […]

Mitigating a DoS attack with GoAccess and Cloudflare

In this off-topic post, I’m going to discuss some behind-the-scenes “fun” that may happen when managing the web server used to host the CNX Software website. From time to time, the server becomes unreachable, but I can still access its console, and notice a very high CPU load (over 100) on a VPS with four cores, while the CPU load is typically 0.5 to 2 under normal circumstances. That’s usually due to a DoS (denial of service), DDoS (distributed denial of service), or some bug I can’t identify. An easy way to solve this issue is to log in to Cloudflare and set the “Under Attack Mode” to on. It will show all visitors a JavaScript challenge the first time they visit the website, and the CPU usage typically drops back to normal level within a minute or so. That means I can access my website and so do regular […]
