Embedded Open Source Summit 2023 schedule – Zephyr OS, Security, IoT, Embedded Linux, and more

The Linux Foundation has just announced the full schedule for the Embedded Open Source Summit, which will take place on June 27-30, 2023 in Prague, Czech Republic, as well as virtually starting on June 26. Over 175 sessions, birds of a feather (BoF) tracks, and workshops related to embedded and open-source innovation will be presented at the event itself comprised of six micro conferences: Automotive Linux Summit Europe, Embedded IoT Summit, Embedded Linux Conference, LF Energy Embedded Summit, Safety-Critical Software Summit, and Zephyr Project Developer Summit. Even though I’m not going to attend personally, I’ve gone through the schedule to create my own little virtual schedule with some sessions relevant that should be interesting to me and hopefully to CNX Software readers. Monday, June 26 (Virtual sessions) The first day of the event will have a Yocto Dev training in the morning, and a bunch of virtual sessions that are […]

Cytron CM4 Maker Board review – Part 2: NVMe SSD, RTC, Buzzer, Grove modules, ChatGPT…

We’ve already checked out Cytron’s CM4 Maker Board kit with a Raspberry Pi CM4 system-on-module and booted the system with the included 32GB “MAKERDISK” Class 10 microSD card preloaded Raspberry Pi OS in the first part of the review. For the second part of the CM4 Maker review, I’ve mostly used the 128GB NVMe SSD provided by the company and played with other features of the board including the RTC, the buzzer, some Seeed Studio grove modules, and even got help from ChatGPT for one of the Python programs I used. Booting Cytron CM4 Maker Board with the “MAKERDISK” NVMe SSD I connected several Grove modules with GPIO and I2C interfaces, a Raspberry Pi Camera Module 3, an Ethernet cable, two RF dongles for a wireless keyboard and mouse, an HDMI cable to a monitor, and finally inserted the provided 5V/3.5A USB-C power adapter. The MAKERDISK SSD comes with Raspberry […]

Pocket AI – A portable NVIDIA RTX A500 eGPU for AI developers, embedded & industrial applications

We’ve previously seen it’s possible to connect an eGPU to a mini PC through a PCIe x16 to M.2 NVMe adapter or a Thunderbolt 3 port, but while it’s fine to install on your desk for gaming or develop AI applications, the eGPU being larger than most mini PCs, it’s a little too big to integrate into products, and potentially inconvenient to carry around. ADLINK Pocket AI portable eGPU changes that with an NVIDIA RTX A500 GPU housed in a 106 x 72 x 25mm box that’s about the size of a typical power bank and connects to a host through a Thunderbolt 3 connector. The company says the upcoming eGPU is mostly designed for AI developers, professional graphics users, and embedded industrial applications, but can also be for gaming. Pocket AI specifications: GPU – NVIDIA RTX 500 Architecture – NVIDIA Ampere GA107 Base clock: 435 MHz Boost clock: 1335 […]

NanoPi R6C review – Ubuntu 22.04, NVMe SSD, USB debug

FriendlyElec has recently announced the NanoPi R6C mini PC that a variant of the Rockchip RK3588S powered NanoPi R6S mini PC and 2.5GbE router that we reviewed with FriendlyWrt/OpenWrt and Ubuntu 22.04 earlier this year, but with just one 2.5GbE and one GbE interface, a built-in M.2 NVMe SSD socket and USB-C Debug UART port for easy external access to the serial console. The company sent me a NanoPi R6C sample for review, but since we’ve already tested the similar NanoPi R6S extensively, I’ll write a single-post mini review this time around, checking out the hardware, and focusing on testing the new features such as the NVMe SSD and the USB debug port when running Ubuntu 22.04. NanoPi R6C unboxing As usual, the device came in a non-descript cardboard package with a few 3M rubber pads. The most obvious change compared to the NanoPi R6S is that all main ports […]

CH32V003 RISC-V MCU gets $1.5 development board, open source GCC toolchain and flasher utility

When we first wrote about the 10-cent CH32V003 RISC-V MCU it was offered in a $7 development board and the closed-source MounRiver Studio IDE had to be used for programming. But things have improved since October 2022, and now, you can buy a CH32V003 board for as little as $1.5 plus shipping, and an open-source GCC toolchain and flasher/downloader are now available. Let’s have a look at the hardware first with the low-cost nanoCH32V003 development board featuring a 48 MHz CH32V003 RISC-V microcontroller with 2KB SRAM and 16KB flash, a USB Type-C port for power, a reset button, and two rows of headers for the GPIOs. MuseLab nanoCH32V003 specifications: MCU – WCH CH32V003F4U6 32-bit RISC-V2A microcontroller up to 48 MHz with 2KB SRAM, 16KB flash (QFN20 package) Expansion – 2x 11-pin headers with up to 18x GPIOs,  1x USART, 1x I2C, 1x SPI, 8-channel 10-bit ADC, 5V, 3.3V, GND Debugging […]

ESP32 MPY-Jama is a MicroPython IDE for ESP32 boards

ESP32 MPY-Jama is a cross-platform MicroPython IDE specifically designed for ESP32 boards with a file manager, a  REPL terminal, real-time dashboards, and various ESP32-specific features. The IDE is an open-source Python program using pyWebView and pySerial plus some JavaScript for the user interface, and the developer of the program, Jean-Christophe Bos, provides binaries for Windows 64-bit and macOS 64-bit Arm or x86. It’s also possible to use it in Linux but needs to be built from source. Some of the key features of the ESP32 MPY-Jama IDE include: MicroPython code editor with syntax highlighting REPL interface Access to information dashboards with real-time data about WiFi and Bluetooth connections, system info with GPIO status, CPU frequency, memory and SPI flash details Easy 2-click methods to connect to WiFi and create an access point Graphical interface to install a new firmware through esptool Ability to create, import, and run “Jama Funcs” mini-applications […]

TerraMaster F4-423 review – A low-power 4-bay NAS tested with Unraid

Hey Karl here. The timing couldn’t have been more opportune when I was asked to review the TerraMaster F4-423 4-bay NAS. Let me explain why. I run Unraid as my OS of choice for my home lab. I have found it easy to maintain and hard to break. My old rig had a 3900X with 3 cores, 6 threads dedicated to docker containers, and the remaining cores running VM’s. It has been a fun and learning experience. I have run it with several different VM configurations over the past few years. The majority of the time I ran 2 VM’s. One personal and one work and I would RDP over to the work VM. If I wanted to game I had a third gaming VM and allocated all resources to it. It’s not super convenient and as convoluted as it sounds. But recently I moved back to my company-provided laptop […]

Quiet, ultrathin AirJet solid state active cooling chips could replace fans

Frore Systems Airjet Mini and Airjet Pro are active cooling chips that are just 2.8mm thick and quietly suck cool air in from the top of the chip before pushing it out the sides with the aim to replace traditional fan-based solutions in ultrabooks, or be integrated into VR headsets and smartphones for improved cooling. Yesterday we saw that cameras could clean themselves with micro-vibrations, and it happens that processors can be cooled with vibrations too as the Airjet chips are comprised of tiny membranes that vibrate at ultrasonic frequencies to generate a flow of air that enters through inlet vents in the top and transformed into high-velocity pulsating jets exiting from one side of the chip. The AirJet module is actually not placed directly on the processor in ultrabooks but on copper pipes because it allows for thinner designs that way. The company says the AirJet Mini and Pro […]
