GEEKOM A8 Review – Part 3: Ubuntu 24.04 tested on an AMD Ryzen 8945HS mini PC

GEEKOM A8 mini PC Review Ubuntu 24.04 Linux

We’ve already checked out GEEKOM A8 mini PC hardware with an unboxing and a teardown, before testing the AMD Ryzen 9 8945HS mini PC in Windows 11 Pro, and we’ll now report our experience with the GEEKOM A8 running Ubuntu 24.04 to see how it performs in Linux. We tested most features of the GEEKOM A8 mini PC on Ubuntu 24.04, ran several benchmarks to compare it to the similar GEEKOM A7 mini PC, performed storage and networking performance testing, ran stress test to check thermal performance, and measured fan noise and power consumption under various conditions. Installing Ubuntu 24.04 on the GEEKOM A8 mini PC As usual, we resized the Windows 11 partition to install Ubuntu 24.04 alongside Microsoft OS using a bootable USB flash drive created with the Ubuntu ISO. But you’ll notice BitLocker is enabled so the Ubuntu 24.04 installation can’t proceed. The installation wizard will ask […]

NiCE5340 SoM packs Nordic nRF5340 MCU, Lattice iCE40 FPGA, and 11 sensors into a tiny 29x16mm form factor

Stefano Viola's NiCE5340 SoM

Stefano Viola’s NiCE5340 SoM is built around a Nordic Semi nRF5340 Bluetooth SoC, an iCE40 FPGA, 11 sensors, a battery charger, and various other peripherals in a 29×16 mm form factor. The nRF5340 used in the SoM is a low-power, dual-core Arm Cortex-M33 SoC with Bluetooth 5.4, Bluetooth LE (BLE), Thread, Zigbee, and other proprietary protocols. Meanwhile, the Lattice iCE40 FPGA features 3520 logic cells, 80 Kbits of embedded Block RAM, I2C, and SPI blocks, and many other features that make it suitable for applications like environmental monitoring, health tracking, and others. Previously, we have written about Unexpected Maker NANOS3, TinyS3, FeatherS3, and ProS3 boards, and ESP32-S3 4G dev board which all fall under the tiny and compact board category but this is the first time we have seen an MCU board with so many features built into a module of that size.

M5Stack CoreS3 SE cost-down ESP32-S3 IoT controller features a 2-inch touch display, a microSD card slot, a speaker, two microphones

M5Stack CoreS3 SE ESP32-S3 IoT controller

The M5Stack CoreS3 SE, also called M5CoreS3 SE, is a cost-down version of the M5Stack CoreS3 IoT controller based on the ESP32-S3 wireless microcontroller with a 2-inch capacitive touch display, a microSD card slot, a USB-C port, a speaker, two microphones, and one Grove connector for expansion. The M5Core S3 SE loses the DIN Base so the associate features are gone and DIN rail mounting is not possible by default anymore. That also means the M5Stack CoreS3 SE controller is about twice as thin, and the color is also different (medium grey vs black grey). Major internal changes include the removal of the camera and the three sensors found in the original model. M5Stack CoreS3 SE specifications with highlights in bold and strikethrough showing differences against the CoreS3 model: Wireless MCU – Espressif Systems ESP32-S3FN16R8 CPU – Dual-core 32-bit Xtensa LX7 microcontroller with AI vector instructions up to 240MHz, RISC-V […]

Inkplate 6 MOTION STM32-powered wireless e-paper display offers higher resolution and faster refresh rates (Crowdfunding)

Inkplate 6 MOTION with enclosure

The Inkplate 6 MOTION is a new product from Soldered Electronics in their Inkplate series of wireless e-paper displays. It is a 6-inch e-paper display with a partial refresh rate of 11fps which reduces obvious latency in rendering dynamic content such as videos, animations, and scrolling text. The display is driven by an STMicroelectronics dual-core STM32H743 microcontroller, with an ESP32-C3 as a secondary processor. It features Wi-Fi and Bluetooth for networking and a host of peripheral interfaces for physical connectivity. It includes several sensors such as a rotary encoder for quick navigation, a gravitational accelerometer with a gyroscope for tracking device orientation, and a motion detection sensor. We covered the original Inkplate 6 display when it launched on Crowd Supply in 2019. The Inkplate 6 is much less expensive than the new model but has a lower screen resolution (800 x 600 px) and slower refresh rates (256ms). Furthermore, it […]
