Orange Pi CM5 – A Raspberry Pi CM4 alternative with up to 16GB RAM, 256GB eMMC flash

Orange Pi CM5 is a system-on-module mostly compatible with the Raspberry Pi CM4 (and upcoming Raspberry Pi CM5?) powered by a Rockchip RK3588S octa-core Cortex-A76/A55 processor that supports up to 16GB LPDDR4 and 256GB eMMC flash compared to the Pi CM4 module that is limited to 8GB RAM and 32GB flash. Since the Rockchip RK3588S has more interfaces than the Broadcom BCM2711 found in the Raspberry Pi CM4, the company added an extra 100-pin board-to-board connector with extra interfaces such as native USB 3.0, SATA III, CAN Bus, and an additional PCIe 2.0 x1 interface for a total of two. Orange Pi CM5 specifications: SoC – Rockchip RK3588S octa-core processor with 4x CortexA76  cores @ up to 2.4GHz, 4x CortexA55 core @ 1.8GHz Arm Mali-G610 MP4 “Odin” GPU with support for OpenGL ES1.1/2.0/3.2, OpenCL 2.2 and Vulkan 1.2 Video decoder – 8Kp60 H.265, VP9, AVS2, 8Kp30 H.264 AVC/MVC, 4Kp60 AV1, […]

NUMA emulation patch boosts Geekbench 6 benchmark results by up to 18% on Raspberry Pi 5

Igalia Engineer, Tvrtko Ursulin has recently submitted a patch to the Linux kernel adding a NUMA (Non-Uniform Memory Access) emulation implementation for arm64 platforms that boosts the performance of 64-bit Arm targets by “splitting the physical RAM into chunks and utilizing an allocation policy to better utilize parallelism in physical memory chip organization”.

The NUMA emulation implementation was tested on a Raspberry Pi 5 SBC and the Geekbench 6 single-core score improved by 6%, while the multi-core score boosted by 18% after splitting into four emulated NUMA nodes. In other words, that’s like having a Broadcom BCM2712 CPU overclocked from 2.4 GHz up to 2.83 GHz.

Olimex NEO6502 is a W65C02 and Raspberry Pi RP2040-powered retro computer with HDMI, USB, and more

Olimex has recently launched NEO6502 an open-source hardware retro computer designed for educational and entertainment purposes, but that doesn’t mean it can’t be used for retro gaming. The board is very unique as it’s built around a 65C02 MPU and Raspberry Pi Pico RP2040 MCU in a dual-processor configuration. The MOS6502 handles the Apple II, Oric, and Commodore 64 emulators whereas the RP2040 handles everything else including HDMI (DVI) video output using the PicoDVI project. Previously we have written about similar retro computer kits such as the CERBERUS 2100, TinyLlama x86, DevTerm with ClockworkPi v3.14, Olimex AgonLight2, and many others feel free to check those out if you are interested in retro tech with a modern twist. Olimex NEO6502 board specifications Processors Western Design Center W65C02S 8-bit microprocessor @ 6.25 MHz with 64kB RAM, 32kB Graphics RAM Raspberry Pi RP2040 dual-core Cortex-M0+ MCU @ 133 MHz with 264 KB SRAM Storage […]

The Pico Display Base Board offers a simpler way to create Raspberry Pi Pico LCD projects

The Pico Display Base Board is a printed circuit board from Applying Microcontroller Solutions that provides a platform for building Raspberry Pi Pico-based display projects. It works with a Raspberry Pi Pico board and an LCD screen based on the Solomon Systech SSD1963 display controller. The Pico Display Base Board features a 40-pin header (Display Port) which connects to GPIO on the Pico to provide an 8-bit parallel interface for the display and SPI pins for the touchscreen and integrated SD card. It supports various display sizes from 4.3 inches up to 7 inches. Displays up to five inches can be powered directly by the Pico. A jumper block on the board can be used to pass power to the LCD and wire the display’s optional flash chip to the Pico. A USB-C port on the board can provide an alternative power source for larger displays. It also has male […]

LimeNET Micro 2.0 Developer Edition board leverages Raspberry Pi CM4 and LimeSDR XTRX SDR module (Crowdfunding)

The LimeNET Micro 2.0 Developer Edition board is a modular software-defined radio (SDR) platform from Lime Microsystems that is based on the Raspberry Pi Compute Module 4 and the company’s own SDR board, the LimeSDR XTRX. It builds upon previous versions from Lime Microsystems, such as the LimeSDR Mini and LimeSDR Mini 2.0. It features a MIMO (multiple-input, multiple-output) radio and runs the more powerful Compute Module 4, an upgrade from the Raspberry Pi CM3 in earlier versions. The LimeSDR XTRX is an open-source, high-performance SDR in a compact, Mini PCIe form factor.  It provides a platform for building logic-intensive digital and RF designs and can be used for MIMO antenna configurations from 2Tx2R to 32Tx32R. The platform is built around a planar system board, the LimePSB RPCM, which integrates the CM4, the XTRX, and other components and interfaces to make a complete baseband + RF solution for diverse wireless […]

Apple’s Embedded Swift programming language supports ESP32-C6, Raspberry Pi RP2040, STM32F7, nRF52840 microcontrollers

Apple has released a beta version of Embedded Swift that notably works with Espressif ESP32-C6 wireless RISC-V microcontroller, and the company also built a Matter sample based on ESP-IDF and ESP-Matter SDKs. Embedded Swift is not limited to the ESP32-C6 and supports other microcontrollers from STMicro, Raspberry Pi, Nordic Semi, etc… Apple Swift programming language is mostly designed for mobile app development, but we’ve also seen it being used on Mad Machine’s SwiftIO board powered by a 600 MHz NXP i.MX RT1052 Arm Cortex-M7 crossover processor and the tiny SwiftIO Micro launched a few years later. The company has now decided to create a subset of the Swift programming language better suited to microcontrollers simply called Embedded Swift that’s currently working on STMicro STM32F746, Raspberry Pi Pico, nRF52840, and ESP32-C6. The “Go small with Embedded Swift” presentation at WWDC 2024 shows how to get started with Embedded Swift using Espressif […]
