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 […]

Year 2022 in review – Top 10 posts and statistics

It’s the last day of the year and the time to look at some of the highlights of 2022, some traffic statistics from CNX Software website, and speculate on what 2023 may bring us. The semiconductors shortage continued in 2022, but things are looking brighter in 2023 with the full reopening of the world mixed with forecasts of difficult economic times that should keep the demand/supply equation in check. On the Arm processor front the biggest news of the year, at least in this corner of the Internet, was the launch of the Rockchip RK3588 octa-core Cortex-A76/A55 processor together with interesting single board computers that we’ll discuss below. Announced last year, the Amlogic A311D2 octa-core Cortex-A73/A53 was finally made available in a few SBC’s, and we finally got some news about the Amlogic S928X Cortex-A76/A55 SoC showcased in 8K TV boxes, but we have yet to see it in action.

Adding an external serial console port to NanoPi R6S

I had no trouble with my first experience with NanoPi R6S while installing and running the FriendlyWrt/OpenWrt 22.03 image, but that was another story when testing Ubuntu or Debian as the mini PC would not boot at all after flashing the images with eFlasher apparently successfully, but suspiciously fast (under 2 seconds). I spent nearly four hours trying the different images and then the Rockchip Windows utility, but all my attempts failed, and FriendlyElec was not overly helpful. So I decided to connect a serial console to see what was going on. The NanoPi R6S comes with a 3-pin header for the serial console, but it’s not populated. So I soldering one, but not at the top of the bottom, and instead at the bottom since it would allow me to still use the metal enclosure to cool the processor. Some readers, or at least one, often complain about the […]

Getting Started with CrowBot BOLT smart robot car

CrowBot BOLT is a smart robot car based on an ESP32 wireless microcontroller and designed for the education market with the ability to program the robot with visual programming, Arduino, or MicroPython. Elecrow sent me a sample of the CrowBot BOLT kit for evaluation so I’ll have a look at the hardware, show how to assemble it, showcase the features of the built-in firmware, and demonstrate how to program the robot with visual programming, Arduino, and MicroPython using some of the provided code samples. CrowBot BOLT unboxing The package lists some of the highlights with 16 teaching courses, support for multiple programming platforms, scalability with Grove connectors, and the inclusion of the Joystick that’s also programmable. The CrowBot BOLT comes as a kit so there will need to be some work to do to assemble the robot, but no soldering is required (in normal cases, more on that later). The […]
