Raspberry Pi 5 gets a PoE HAT+ kit that doubles as a cooling solution

Waveshare PoE HAT(F) is an 802.3af/at-compliant 24W Power-over-Ethernet (PoE) HAT+ board designed for the Raspberry Pi 5 that also cools the SBC with its embedded fan, a heatsink, and two thermal pads. The Chinese company has beaten Raspberry Pi to it as the UK company is working on releasing the L-shaped 25W “PoE+ HAT(+) for Raspberry Pi 5” a little later. The existing official Raspberry Pi PoE+ HAT delivers up to 25.5 Watts which would be enough to power the Pi 5, but since the PoE header has been moved to another location, it’s not compatible anymore, so new solutions are needed such as the Waveshare PoE HAT(F). Waveshare PoE HAT(F) specifications: Supported SBC – Raspberry Pi 5 only Connected via 40-pin Raspberry Pi GPIO header and 4-pin PoE header PoE (Power Over Ethernet) IEEE 802.3af/at-compliant Input voltage – 37V-57V DC input Output 2-pin header – 12V/2A max GPIO header […]

Raspberry Pi 5 industrial HMI displays gain M.2 NVMe SSD, RS232/RS485 interfaces, audio input/output jacks

Raspberry Pi 5 industrial HMI with RS232/RS485 audio input/output jacks

EDATEC ED-HMI3020 is a family of Raspberry Pi 5-based industrial HMI displays that build upon the earlier ED-HMI3010 panel PCs by adding an M.2 socket for NVMe SSD, RS232 and RS485 interfaces, as well as 3.5mm audio input and output jacks. The new models are still offered with either a 7-inch (1024×600) or 10.1-inch (1200×800) touchscreen display, a Raspberry Pi 5 with 4GB or 8GB RAM with all main ports (HDMI, Ethernet, USB) accessible externally, and support for an optional 8MP front-facing camera. ED-HMI3020 specifications with differences again ED-HMI3010 highlighted in bold or strikethrough: SoC – Broadcom BCM2712 CPU – Quad-core Arm Cortex-A76 processor @ 2.4 GHz with crypto extensions, 512KB per-core L2 caches, 2MB shared L3 cache GPU – VideoCore VII GPU @ 800 MHz with support for OpenGL ES 3.1, Vulkan 1.2, 4Kp60 HEVC decoder System Memory – 4GB or 8GB LPDDR4X-4267 SDRAM Storage MicroSD card socket M.2 […]

SB’s Dual Roundy and Squary Displays are powered by RP2040 or ESP32-S3 microcontrollers (Crowdfunding)

Dual Display Modules Roundy and Squary by SB Components

SB-Components has launched Dual Roundy and Dual Squary display modules powered by Raspberry Pi RP2040 or ESP32-S3 microcontrollers. These compact modules feature a 6-DoF IMU, interchangeable displays, and multiple storage and connectivity options. The Dual Roundy is equipped with two 1.28-inch round displays, with a 240 x 240 resolution, and uses the GC9A01 display driver IC. In contrast, the Dual Squary features two 1.54-inch square displays with a 240 x 240 resolution but utilizes the ST7789 display driver. Both displays offer a choice between a Raspberry Pi RP2040 MCU and the ESP32-S3-WROOM-1 module catering to different needs in performance and wireless capabilities. We’ve previously explored other rounded displays like the MaTouch ESP32-S3, T-RGB ESP32-S3, and ESP32-S3 Round SPI TFT. We’ve also examined other products from SB Components such as the Cluster HAT, PiMecha, PiTalk 3G HAT, and Micro RP2040. Feel free to check these out for more interesting tech insights. […]

SunFounder PiCar-X 2.0 review – A Raspberry Pi 4 AI robot car programmable with Blockly or Python

SunFounder PiCar-X 2.0 is an AI-powered self-driving robot car using the Raspberry Pi 3/4 as the main processing board. It is equipped with a camera module that can be moved by a 2-axis servo motor, allowing the camera to pan or tilt, an ultrasonic module for detecting distant objects, and a line detection module. The PiCar-X robot can also perform computer vision tasks such as color detection, face detection, traffic signs detection, automatic obstacle avoidance, and automatic line tracking. The PiCar-X can be programmed with two computer languages: Blockly-based Ezblock Studio drag-and-drop program and Python, and the robot works with OpenCV computer vision library and TensorFlow for AI workloads. Finally, you can also control the robot through the SunFounder controller application on your mobile phone. The company sent us a sample of the Picar-X 2.0 for review, so let’s get started. SunFounder PiCar-X 2.0 robot overview The PiCar-X robot kit […]

Linux 6.7 release – Main changes, Arm, RISC-V, and MIPS architectures

Linus Torvalds has just announced the release of Linux 6.7, following Linux 6.6 LTS a little over two months ago: So we had a little bit more going on last week compared to the holiday week before that, but certainly not enough to make me think we’d want to delay this any further. End result: 6.7 is (in number of commits: over 17k non-merge commits, with 1k+ merges) one of the largest kernel releases we’ve ever had, but the extra rc8 week was purely due to timing with the holidays, not about any difficulties with the larger release. The main changes this last week were a few DRM updates (mainly fixes for new hw enablement in this version – both amd and nouveau), some more bcachefs fixes (and bcachefs is obviously new to 6.7 and one of the reasons for the large number of commits), and then a few random […]

Tillitis Tkey is an open-source RISC-V security key in a USB-C case

Tillitis’ TKey is a small, simple security key in a USB-C form factor, and described as a “new type of flexible USB security token” that is inspired by DICE (Device Identifier Composition Engine) and measured boot powered by a simple 32-bit RISC-V core, the PicoRV32, in a Lattice iCE40 UP5K FPGA. While we have covered hardware security modules in the past, this is the first security key we have seen that is based on an FPGA running a RISC-V core. The security token lacks persistent, onboard storage, unlike alternatives such as Yubikey Neo. Apps need to be loaded onto the key every time it is connected to a host device. It uses measured boot to generate a unique identifier for each application and is more secure than the alternatives since private keys are not stored on the device. Also, the hardware and software for the TKey are completely open-source for […]

2023 Year in review – Top 10 posts, statistics, and what to expect in 2024

It’s the last day and last article of the year, so we will look at some highlights of 2023, some traffic statistics on the CNX Software website, and speculate what interesting developments may happen in 2024. Looking back at 2023 The semiconductor shortage that had happened since 2020 started to fade away in early 2023, and supplies for most electronics components and devices seem to be adequate at this time, so that was a bright spot this year, and hopefully, it will stay that way in 2024 despite geopolitical tensions. We did not have any super exciting new Arm application processors from Rockchip, Amlogic, or Allwinner announced this year, although the Amlogic S928X penta-core Cortex-A76/A55 CPU started to show up in some 8K TV boxes. The launch of the Raspberry Pi 5 SBC with a Broadcom BCM2712 quad-core Cortex-A76 processor was probably the main highlight for Arm on this side […]

Sipeed Longan Pi3H – A Raspberry Pi Zero-sized board with gigabit Ethernet, WiFi 6, HDMI, and USB ports

Sipeed Longan Pi3H is a Raspberry Pi Zero-sized single board computer (SBC) powered by an Allwinner H618 quad-core Cortex-A53 processor and equipped with full-size connectors namely an HDMI 2.0 video output, two USB 2.0 Type-A ports, and a gigabit Ethernet RJ45 jack. It also offers WiFi 6 and Bluetooth 5.4 connectivity, features the usual 40-pin GPIO header found in Pi Zero boards and relies on a USB OTG Type-C port for power. Its design is unusual for a board of that size, not only because of the full-size ports, but also because it’s comprised of a carrier board and a replaceable LM3H CPU module with the Allwinner H618 SoC, RAM, and eMMC flash. Sipeed Longan Pi3H specifications: SoC – Allwinner H618 CPU – Quad-core Arm Cortex-A53 processor @ up to 1.5GHz with 1MB L2 cache GPU – Arm Mali-G31 MP2 GPU with support for OpenGL ES 1.0/2.0/3.2, OpenCL 2.0, Vulkan […]
