Sfera Labs Strato Pi Max DIN rail industrial controllers now support the Raspberry Pi Compute Module 5

The Raspberry Pi Compute Module 5 (CM5) was launched at the end of last month, and we are starting to see companies slowly announce upgraded CM4 designs. Yesterday, we wrote about EDATEC ED-IPC3100 DIN-Rail mountable industrial computers, and today, we’ll cover Sfera Labs’ addition of the Raspberry Pi Compute Module 5 to their Strato Pi Max DIN rail industrial controllers. The controllers still feature a gigabit Ethernet port, a 10/100M Ethernet port, two USB 2.0 ports, a Raspberry Pi RP2040 microcontroller for power management and boot sequence control, and support expansion modules for up to sixteen RS-485 or RS-422 ports, four CAN V2.0B ports, digital and analog I/O, and more. Strato Pi Max specifications (as of December 2024): Base Module Raspberry Pi Compute Module 5 Raspberry Pi Compute Module 4 Zymbit SCM options. Microcontroller – Raspberry RP2040 dual ARM Cortex-M0+ at 133 MHz. Storage – eMMC, microSD (dual for XL), M.2 PCIe […]

Raspberry Pi 500 keyboard PC launched together with 15.6-inch Raspberry Pi Monitor

The Raspberry Pi 500 keyboard PC is now available with the guts of a Raspberry Pi 5 including a Broadcom BCM2712 quad-core Cortex-A76 SoC, 8GB LPDDR4x and a 32GB microSD pre-loaded with Raspberry Pi OS. But the company also took the opportunity to launch the 15.6-inch Raspberry Pi Monitor that was first showcased at Embedded World 2024. That means Raspberry Pi launched 22 products this year including kits, and we’re promised that would be the last launch for 2024! But Pi fans can expect a small surprise in the first half of January… Raspberry Pi 500 keyboard PC Raspberry Pi 500 specifications: SoC – Broadcom BCM2712 CPU – Quad-core 64-bit Arm Cortex-A76 processor @ 2.4GHz GPU – VideoCore VII GPU with support for OpenGL ES 3.1 graphics, Vulkan 1.2 VPU – 4Kp60 HEVC decoder System Memory – 8GB LPDDR4X-4267 SDRAM Storage – 32GB microSD card preloaded with Raspberry Pi OS […]

BredOS Arch Linux Arm distribution runs on Rockchip RK3588 single board computers

BredOS is a Linux distribution based on Arch Linux Arm and optimized to run on Rockchip RK3588/RK3588S single board computers (SBCs) with current support for 22 boards from Radxa, Orange Pi, Khadas, and others. Board vendors will usually provide OS images for their SBCs, but the quality and support may be limited, so projects like Armbian and DietPi are maintaining Ubuntu and/or Debian images for popular single board computers. But if you’re an Arch Linux (Arm) fan, there are fewer choices, and you may have to roll your own port for your board. BredOS provides an easy-to-use alternative based on Arch Arm Linux. BredOS highlights (provided by the developers): User-Friendly Interface – A simplified and intuitive user interface for easy navigation and use. Arch-Based – Built on top of Arch Linux, ensuring access to a vast repository of packages and a rolling release model. Arm Support – Optimized for Arm-based […]
