SunFounder PiPower 3 kit is a UPS solution for the Raspberry Pi 5 SBC

Raspberry Pi 5 UPS Solution

SunFounder PiPower 3 kit is a UPS solution designed to work with the Raspberry Pi 5, other Arm SBCs, or even MCU boards like Arduino UNO and Raspberry Pi Pico. The board delivers a stable 5V/5A output, and a 32-bit CH32V003 RISC-V microcontroller takes care of power management and battery level reporting to make sure the Raspberry Pi 5 keeps running when a power failure occurs and shutdowns gracefully when the battery level is low. The kit comes with two 18650 2,000mAh batteries that connect through a 2-pin connector, and all accessories – standoffs, acrylic case, and fan – for assembly with the Raspberry Pi 5, or other compatible boards like the Pi 4, Banana Pi BPI-M5, Radxa Rock Pi E, Orange Pi 3B, and others.   PiPower 3 kit specifications: 32-bit CH32V003 RISC-V microcontroller supporting I2C communication Input – 5V/5A via USB Type-C with PD support Output – 5V/5A […]

N-Fuse PoE HAT for the Raspberry Pi 5 also includes mini PCIe or M.2 Key-M/E/B sockets

Raspberry Pi PoE HAT M2 socket

N-Fuse has designed a PoE HAT for the Raspberry Pi 5 SBC that also serves as a PCIe expansion board thanks to either a mini PCIe socket or an M.2 Key-M, Key-B, or Key-E socket supporting 2230, 2242, or 3042 modules such as SSDs, AI accelerators, or wireless modules. The SBCPoE RPi5 HAT complies with the latest 802.3bt standard delivering up to 25W with active cooling or 15W with passive cooling. The HAT board still allows users to make use of the 40-pin Raspberry Pi 5 header thanks to a 40-pin Raspberry Pi interposition header. SBCPoE RPi5 HAT specifications: Power Supply IEEE 802.3af/at/bt compliant Overload protection 25W power delivery with active cooling, 15W without active cooling Output current up to 5A 5V output via optional 2.54mm pin header High efficiency (> 85%) enabled by active MOSFET bridge rectifier Short-Circuit Duration – infinity PCIe expansion (one or the other) Mini PCIe […]

RAUC open-source OTA update solution for embedded Linux ported to Rock Pi 4 SBC

RAUC OTA firmware update Rock Pi 4

RAUC open-source OTA update solution enabling A/B updates for embedded Linux images has recently been ported to the Radxa Rock Pi 4 Model B SBC powered by a Rockchip OP1 SoC by the project’s maintainer, Leon Anavi working for Konsulto Group. If you run a Linux distribution like Ubuntu, Debian, or Fedora, packages and OS images are taken care of automatically or by running a few commands. However, software engineers who build custom embedded Linux images with the Yocto Project or Buildroot must handle this themselves. Luckily, there are already open-source OTA firmware update solutions such as Mender, Balena, Torizon, OSTree, Snap, or RAUC, and we’ll look at the latter today. RAUC (Robust Auto-Update Controller) was started by Pengutronix in 2015 and eventually adopted by the community. It’s a lightweight update client that runs on an Embedded Linux device and controls the A/B update procedure when a new firmware revision […]

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

Raspberry Pi 5 NUMA emulation

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.

PCIe to 5G HAT+ for Raspberry Pi 5 takes SIMCom and Quectel 5G modules

Raspberry Pi 5 5G PCIe HAT+

Waveshare PCIe to 5G/4G/3G HAT+ for Raspberry Pi 5 is a PCIe Gen 2 x1 to M.2 HAT+ designed to take 5G modules from SIMCom and Quectel and a Nano SIM card. The kit ships with a 4-in-1 PCB antenna, associated cables, a heatsink, a 4cm 16-pin PCIe FPC cable, a 40-pin female header, and a fixture set for mounting. We had previously written about the SixFab 5G HAT for the Raspberry Pi 5 with a Quectel RM502Q-AE M.2 module, but this specific kit still relies on the USB 3.0 interface. The Waveshare kit is the first 5G kit using the PCIe interface from the Raspberry Pi 5 interface and it is offered with Quectel RM502Q-AE, RM530N-GL, RM520N-GL, or SIMCom SIM8262E-M2, SIM8262A-M2 M.2 3042/3052 modules. Waveshare PCIe to 5G HAT+ specifications: M.2 Key B socket for 3042/3052 5G modules with PCIe interface 16-pin PCIe FPC connector directly connected to the […]

Ochin V2 tiny Raspberry Pi CM4 robotics carrier board gets micro HDMI port, Fast Ethernet support

Ochin V2 CM4 robotics carrier board and USB-C board

Ochin V2 is an update to the tiny Ochin Raspberry Pi CM4 carrier board for robotics applications and drones that adds a micro HDMI port, support for Fast Ethernet through pads or a GHS connector (no RJ45 connector), two user LEDs, and a few other changes. The form factor remains the same at just 55 x 40 x 4.7mm, or about the size of a Raspberry Pi Compute Module 4, which in combination with a range of USB, UART, I2C, and SPI interfaces, makes it an ideal candidate for space-constrained applications such as robotics system or UAVs. Ochin V2 specifications (differences against Ochin v1 shown in bold or strikethrough): Supported modules – Raspberry Pi CM4 with Broadcom BCM2711 quad-core Cortex-A72 processor, up to 8GB RAM, up to 32GB eMMC flash (the CM4 Lite is not supported since there’s no microSD card on the board), 4Kp60 H.265 decode, 1080p30 H.264 encode, […]

picoLLM is a cross-platform, on-device LLM inference engine

picoLLM Raspberry Pi 5

Large Language Models (LLMs) can run locally on mini PCs or single board computers like the Raspberry Pi 5 but with limited performance due to high memory usage and bandwidth requirements. That’s why Picovoice has developed the picoLLM Inference Engine cross-platform SDK optimized for running compressed large language models on systems running Linux (x86_64), macOS (arm64, x86_64), and Windows (x86_64), Raspberry Pi OS on Pi 5 and 4, Android and iOS mobile operating systems, as well as web browsers such as Chrome, Safari, Edge, and Firefox. Alireza Kenarsari, Picovoice CEO, told CNX Software that “picoLLM is a joint effort of Picovoice deep learning researchers who developed the X-bit quantization algorithm and engineers who built the cross-platform LLM inference engine to bring any LLM to any device and control back to enterprises”. The company says picoLLM delivers better accuracy than GPTQ when using Llama-3.8B MMLU (Massive Multitask Language Understanding) as a […]
