Cooler Master Pi Case 40 V2 Raspberry Pi 4

Cooler Master Pi Case 40 V2 case for Raspberry Pi 4 is the successor of the fanless Pi Case 40 metal enclosure launched in 2020 on Kickstarter. The company also offers 3D files for the case and accessories to expand its functionality. Cooler master Pi Case 40 V2 (MCM-PI400-MNNN-S01) specifications: Designed for Raspberry Pi 4 Model B Access to internal Raspberry Pi interfaces – 40-pin GPIO header, SD card, display, and camera I/F Misc – Remappable power button Dimensions – 96 x 68.2 x 27.3mm (excl. protrusions) or 28.58mm (incl. protrusions) Color(s) – Gun Metal Grey, Black Materials – Aluminum, Plastic, TPU The fanless enclosure ships with four modular mounting brackets, one Allen Key, two Thermal Pads, a 90° GPIO adapter, an ON/OFF switch, and a 40-pin jumper cable. It will not work with most/any other board compatible with Raspberry Pi 4 due to the different positions of the CPU. […]

FOMO (Faster Objects, More Objects) enables real-time object detection on low-end embedded systems

FOMO used to stand for “Fear Of Missing Out” in my corner of the Internet, but Edge Impulse’s FOMO is completely different, as the “Faster Object, More Objects” model is designed to lower the footprint and improve the performance of object detection on resource-constrained embedded systems. The company says FOMO is 30x faster than MobileNet SSD and works on systems with less than 200K of RAM available. Edge Impulse explains the FOMO model provides a variant between basic image classification (e.g. is there a face in the image?) and more complex object detection (how many faces are in the image, if any, and where and what size are they?). That’s basically a simplified version of object detection where we’ll know the position of the objects in the image, but not their sizes. So instead of seeing the usual bounding box while the model is running, the face position will be […]

Getting started with Maker Nano RP2040 using CircuitPython: Blinky, RGB LED, and Piezo Buzzer

CNXSoft: This getting started guide was initially posted in Thai language by Suthinee Kerdkaew, and I’ve just translated her work into English with some minor edits. As discussed in an earlier article, Maker Nano RP2040 is a board following the Arduino Nano form factor, but with a more powerful Raspberry Pi RP2040 microcontroller. The board also comes with plenty of LEDs, as well as two RGB LEDs, and a piezo buzzer for audio output. Mr. Jean-Luc Aufranc has just given me a Maker Nano RP2040 board received from Cytron for review. I’ve never used a board before, so it’s my first experience, and in this article, I’ll try to program Maker Nano RP2040 with CircuitPython with three demos: a blinky sample, changing the color of the RGB LEDs, and playing a melody through the piezo buzzer. Let’s see if I can do it. Let’s get started. I first downloaded the […]

RAKwireless adds more Wisduo and Wisblock modules, launches WisToolBox configuration tool for IoT devices

RAKwireless have launched several Wisduo wireless modules, a dozen of Wisblock modules for IoT prototyping, updated WisDM, WisGateOS, and RUI3 software, and introduced WisToolBox mobile/desktop configuration tool for IoT devices as part of their spring launch 2022 even entitled “Empowering the Innovators: Making IoT your own”. Three new Wisduo modules RAK3172-SIP WisDuo SIP based on STM32WLE5 Wireless SoC with LoRa connectivity. Compared to the original RAK3172, it offers more IO pins, integrates a TCXO, and comes in a smaller size. The module supports LoRa P2P and complies with Class A, B, & C of LoRaWAN 1.0.3 specifications. Cost: $5.99. WisDuo RAK3272-SiP – That’s a breakout board for the RAK3172-SiP System-in-a-Package module for LoRaWAN and allows easy access to all pins via 2.54mm pitch headers. RAK4630 WisDuo Stamp Module – This module supports both LoRa/LoRaWAN and BLE 5.0, and comes with RUI V3 (RUI3) firmware. It can be deployed as an […]

Raspberry Pi OS removes default “Pi” username, adds experimental support for Wayland

The Raspberry Pi Foundation has just released a new version of Raspberry Pi OS that removes the default username (pi) for security reasons, adds experimental support for Wayland, and lets people configure their Raspberry Pi with Bluetooth keyboard and mouse. Default username no more The most significant change in the new Raspberry Pi OS is the removal of the default “pi” user as several countries have legislation against default credentials for security reasons. That includes the Product Security and Telecommunications Infrastructure Bill (PSTI) in the UK, and California’s SB-327 IoT devices security law. Those laws mostly target default passwords, but removing a default username can be useful too to prevent force brute attacks. One consequence of removing the default username is that you won’t be able to skip the wizard in both the Desktop and Lite versions of Raspberry Pi OS since a new user needs to be created first. […]

Arducam Pi Hawk-eye is a 64MP camera for Raspberry Pi 4/CM4

Arducam Pi Hawk-eye is a 64MP “ultra-high resolution” camera for Raspberry Pi 4 or CM4 with built-in autofocus following the company’s 16MP autofocus camera introduced at the end of last year. The new camera module will allow you to take still images at up to 9152 x 6944 resolution, but videos will still be limited to 1080p30 on the Raspberry Pi 4. The Pi Hawk-eye is also compatible with the official Raspberry Pi v1/v2 cameras, meaning you can reuse your enclosures/mounts, and keep on using the same software, for instance, libcamera. Arducam Pi Hawk-eye specifications: Sensor – Sensor with 9152 x 6944 pixels resolution Still resolution – 64MP Video modes On Raspberry Pi – 1080p30, 720p60, and 640×480 @ 60/90fps Camera module – 1280×720 @ 120 fps, 1080p60, 2312×1736 @ 30 fps, 3840×2160 @ 20 fps, 4624×3472 @ 10 fps, 9152×6944 @ 2.7 fps Optical size – 9.25mm diagonal (7.4×5.5mm) […]

Raspberry Pi Compute Module 4S SO-DIMM module is powered by Broadcom BCM2711 SoC

The Raspberry Pi Compute Module 4S is an upcoming system-on-module based on the same Broadcom BCM2711 quad-core Cortex-A72 processor found in Raspberry Pi Compute Module 4, but using the same SO-DIMM connector as found in earlier Raspberry Pi Compute Module boards, instead of the new board-to-board connectors. The Raspberry Pi Compute Module 4S is not launched yet, but we discovered it will be used on Revolution Pi S and SE series DIN-rail industrial computers via a tweet from Jeff Geerling and his post on Raspberry Pi forums. Apart from the faster processor and support for 4K video output, The Raspberry Pi Compute Module 4S is quite similar to the Raspberry Pi Compute Module 3+. Memory bandwidth might be a little better with the LPDDR4 memory too (TBC), but all the rest looks the same. The main advantage of the new Raspberry Pi CM4S module is compatibility with older SO-DIMM carrier […]
