SBC Case Builder v3.0 can create thousands of cases for popular SBCs and standard motherboards (mini-ITX, Pico-ITX, NUC…)

SBC Case Builder V3.0 case design utility has just been released with the ability to create over 1,000 standard cases – not including customization – for popular SBCs from Raspberry Pi, Hardkernel, Orange Pi, Radxa, and others, as well as standard motherboards following Mini-ITX, Pico-ITX, NUC, Nano-ITX, etc.., and SBC adapters following these standards, meaning you could install a Raspberry Pi 5 into a mini-ITX case if needed. SBC Case Builder started as a command line utility for designing DIY case for SBCs relying on OpenSDAD in April 2022, but Edward Kisiel (hominoids) quickly released version 2 with a GUI in October or the same, and has now further improved the utility with the release of SBC Case Builder v3.0. Version 3.0 comes with many improvements but the main focus was to reuse existing and new PC standard form factor cases by creating SBC adapters and custom I/O Shields since […]

M5Stack CoreMP135 – A Linux-powered industrial controller based on STM32MP135 Cortex-A7 MPU

M5Stack CoreMP135 industrial control host

M5Stack CoreMP135 is an industrial control host powered by the STM32MP135DAE7 Arm Cortex-A7 core microprocessor running at 1GHz, equipped with up to 512MB DDR3L SDRAM memory, and loaded with high-performance interfaces such as two Gigabit Ethernet ports, three USB ports, two CAN FD interfaces, two Grove interfaces, and an “HD” video output. An integrated PWR485 communication board bundles a 9V to 24V power input and an RS485 interface. The device also features a microSD card slot for storage, a small IPS capacitive touch screen, and a 1W speaker for human-machine interaction. The CoreMP135 is designed for low-power consumption and uses an Allwinner AXP2101 chip for power management. It supports scheduled wake-up and sleep with an integrated real-time clock (BM8563 module). The device runs Linux and comes with a microSD card loaded with the Debian operating system, simplifying setup and allowing usage out of the box. A DIN rail base plate […]

Review of SONOFF SNZB-06P human presence and SNZB-04P door/window Zigbee sensors

SONOFF has been gradually refreshing its Zigbee product lineup since August 2023, and CNX has recently written about the Temperature/Humidity Sensor (SNZB-01P), Switch/Button (SNZB-02P) and Motion Sensor (SNZB-03P), and the SONOFF SNZB-06P human presence sensor. I’ve now had the opportunity to review both the SONOFF SNZB-06P and the new Door/Window Sensor (SNZB-04P). After we keep trying them out for a few weeks, we think reliability is much improved, especially with the Door/Window Sensor, the materials made as well as the appearance look better than the previous models. As for the Human Presence Sensor, it’s the first generation, which is quite impressive considering its price and features. Let’s take a closer look. Door/Window Sensor (SNZB-04P) review Unboxing Obviously, the rounded design differs from the previous rectangular version. It integrates better with the surroundings than the previous model. Additionally, the lithium battery capacity is larger (CR2450 @550mA vs. CR2477 @1000mA), resulting in […]

Raspberry Pi 5 vs Intel N100 mini PC comparison – Features, Benchmarks, and Price

The Raspberry Pi 5 Arm SBC is now powerful enough to challenge some Intel systems in terms of performance, while Intel has made the Intel Alder Lake-N family, notably the Intel Processor N100, inexpensive and efficient enough to challenge Arm systems when it comes to price, form factor, and power consumption. So we’ll try to match the Raspberry Pi 5 to typical Intel processor N100 mini PCs with a comparison of features/specifications, performance (benchmarks), and pricing with different use cases. That’s something I’ve been wanting to look into for a while but I was busy with reviews and other obligations (Hello, Mr. Taxman!), and this weekend I had some spare time to carry on the comparison. Raspberry Pi 5 vs Intel N100 mini PC specifications I’ll start by comparing the specifications of a Raspberry Pi 5 against the ones for typical Intel Processor N100-based mini PCs also mentioning optional features […]

Olimex ESP32-POE2 board offers up to 25W for power-intensive applications

The Bulgarian hardware manufacturer, Olimex, has designed a new ESP32 board with Power over Ethernet (PoE) functionality. The Olimex ESP32-POE2 board builds on the original ESP32-POE and features the same ESP32-WROOM-32 microcontroller module with Wi-Fi and Bluetooth connectivity. However, it supports up to 25W power delivery from the Ethernet port via PoE and can be used in more demanding projects. The Olimex ESP32-POE2 board features a low-power design and consumes only 200µA in deep sleep mode. The board can be powered via USB-C, Ethernet, or Li-Po battery. The Ethernet interface is built on Texas Instruments’ TPS2378PW chip with IEEE 802.3at classification and legacy PoE support. Powering with PoE requires at least 37V DC for seamless operation. Two proprietary connectors (UEXT and EXT1) can be used to add sensors and other modules and expand the board’s operation for IoT projects. Users can select between 24V/0.75A or 12V/1.5A power output, with a […]
