Raspberry Pi 5 review – Part 2: Raspberry Pi OS Bookworm, benchmarks, power consumption, and more

Raspberry Pi 5 Review Raspberry Pi OS Bookworm

A few days ago I finally went through the Raspberry Pi 5 kit I received last September going through all the items and booting it with Raspberry Pi OS bookworm. I’ve now had time to perform more tests to check out the performance with benchmarks and test various features on the Raspberry Pi 5. So I’ll report my experience in the second part of the review and compare the Raspberry Pi 5 SBC to the Raspberry Pi 4 and some other Arm Linux SBCs.

System information in Raspberry Pi OS Bookworm

Last time around, I installed the Raspberry Pi 5 in its official case, but for most of the testing, I decided to go back to the bare board fitted with its active cooler since it’s the best cooling option as we’ll see further in the review.

Makeblock mBot Neo robot review with Smart World Add-on Pack

MakeBlock mBot Neo, also known as mBot2, is an educational robot that builds upon the previous generation mBot1 robot, and the company has sent us a review sample, following our earlier review of the Ultimate 2.0 10-in-1 educational robot kit, along with the Smart World Add-on Pack. The mBot Neo features a new ESP32-based CyberPi control board with WiFi connectivity for IoT and AI support. The robot is also equipped with a 2nd generation Ultrasonic sensor with improved object detection accuracy and status indicator, a built-in 4-ch RGB line sensor that can detect colors, as well as a new drive motor that comes with an encoder for more precise motion control. The mBot Neo robot kit is expandable with metal parts from other Makeblock models, mBuild modules and various electronic modules can be added making it also possible to build custom robots with third-party structural parts. The mBot Neo robot […]

ESP32 Arduino Core 3.0.0 adds support for ESP32-C6 and ESP32-H2

Espressif Systems has now released an alpha version of ESP32 Arduino Core 3.0.0 enabling the new ESP32-C6 and ESP32-H2 targets to be programmed with the Arduino IDE, and including a number of new features made possible by the ESP-IDF 5.1 SDK. Announced in 2021, the ESP32-C6 WiFi 6, Bluetooth 5 LE, and 802.15.4 wireless MCU became available in modules and devkits at the beginning of this year, but so far they could only be programmed with the latest version (5.1) of the ESP-IDF framework, and so was the new ESP32-H2 Bluetooth 5.2 and 802.15.4 (Zigbee/Thread) MCU. But fans of Arduino programming can now rejoice as an alpha version of ESP32 Arduino Core 3.0.0 brings support for the new microcontroller, and a stable release is planned for December 2023. But as you can probably imagine ESP32 Arduino Core 3.0.0 will also bring lots of other changes since the ESP32 Arduino Core […]

$150 BeagleV-Fire SBC features Microchip PolarFire RISC-V SoC FPGA, supports BeagleBone capes

BeagleV-Fire is a new single board computer powered by Microchip PolarFire MPFS025T penta-core RISC-V SoC FPGA that follows the BeagleBone Black form factor for compatibility with BeagleBone capes expansion boards. Microchip PolarFire RISC-V SoC FPGA was one of the first Linux-compatible RISC-V SoCs and was found in pricey boards such as the Icicle and TySOM-M-MPFS250 development boards. I also got an Icicle board for review, and while getting started with the Yocto Linux BSP was OK, I really struggled with the FPGA part including just installing Libero SoC in Ubuntu and going through the license, and even I gave up trying to run a bitstream sample on the board due to a lack of time. The BeagleV-Fire makes it much cheaper to try out the PolarFire and hopefully makes it easier to get started with both Linux and the FPGA fabric through easier-to-understand documentation and code samples. BeagleFire-V specifications: SoC […]

Arm makes strategic investment in Raspberry Pi

Arm has just acquired a minority stake in Raspberry Pi through a strategic investment in order “to deliver critical solutions for the Internet of Things (IoT) developer community.” Paul Williamson, SVP and GM, Internet of Things Line of Business, Arm explains the rationale behind the investment: Arm and Raspberry Pi share a vision to make computing accessible for all, by lowering barriers to innovation so that anyone, anywhere can learn, experience and create new IoT solutions. With the rapid growth of edge and endpoint AI applications, platforms like those from Raspberry Pi, built on Arm, are critical to driving the adoption of high-performance IoT devices globally by enabling developers to innovate faster and more easily. This strategic investment is further proof of our continued commitment to the developer community, and to our partnership with Raspberry Pi. Eben Upton, Raspberry Pi founder and CEO, also provided remarks: Arm technology has always […]

ADATA SE920 USB4 external SSD offers up to 2TB capacity, supports up to 3,800 MB/s data transfers

ADATA SE920 is a small USB4 external SSD with 1TB or 2TB storage capacity that leverages the 40 Gbps connection enabled by USB4 and delivers up to 3,800 MB/s sequential read speed. The storage device supports Thunderbolt 3 & 4 and is backward compatible with USB 3.2 and USB 2.0 standards. The USB-C port makes it suitable for mini PCs, laptops, SBCs, and even smartphones, but one potential downside of the small form factor is that it integrates a fan to cool the SSD although the user can enable/disable it by extending/retracting the telescopic case. ADATA SE920 specifications: Capacity – 1TB / 2TB Host interface – USB4 up to 40Gbps, backward compatible with USB 3.2/2.0 Performance Sequential Read – Up to 3,800 MB/s, or in other a 10GB file can be transferred in about 3 seconds Sequential Write – Up to 3,700 MB/s (USB4) or up to 3,200 MB/s (Thunderbolt […]

Rockchip roadmap reveals RK3576 and RK3506 IoT processors, Linux 6.1 SDK

The Rockchip RK3588 processor may remain the most powerful processor from the company for a while as an updated Rockchip IoT processor roadmap reveals the new RK3576 octa-core SoC and RK3506 tri-core Cortex-A7 chip, as well as a Linux 6.1 SDK to be released in Q4 2023. With the limited information we have, the Rockchip RK3576 looks to be a cost-down version of the RK3588 processor with eight cores, a 6 TOPS NPU, a 4K video codec, as well as PCIe and USB-C interfaces. Strangely the Rockchip RK3582 that should serve a similar purpose is not showing up in the roadmap. [Update: The RK3576 is indeed a lower-cost SoC but features four Cortex-A72 and four Cortex-A53 cores instead as per the comparison table reproduced below: That also means we now have the RK3576 specifications (some obtained from another document too): CPU Octa-core Arm processor with 4x Cortex-A72 cores at 2.2 […]
