ESP32-C3 AWS IoT ExpressLink module & devkit aim to ease connection to AWS IoT services

Amazon and Espressif have launched another wireless module with the ESP32-C3 AWS IoT ExpressLink module together with a development kit supporting out-of-the-box AWS IoT connectivity, following their earlier collaboration with the launch of the ESP32-PICO-V3-ZERO Alexa Connect Kit Module last summer. Also called the “ESP32-C3-MINI-1-N4-A”, the ESP32-C3 AWS IoT ExpressLink module implements the AWS IoT ExpressLink specification and provides AWS IoT Core connectivity to a host MCU via AT commands over a UART interface. Pre-provisioned and pre-programmed with ease integration the module supports WiFi configuration, messaging, OTA, and device management.   The compact (16.6 x 13.2mm) ESP32-C3 module is currently offered as part of the ESP32-C3-AWS-ExpressLink-DevKit development board following the Arduino Zero board form factor allowing it to be plugged into the Arduino board, or easily connect to other host systems such as the Raspberry Pi. The goal is to simplify the deployment of IoT solutions removing the need for […]

Octo4a app installs OctoPrint server on Android smartphones

Octoprint is a popular open-source 3D printer controller software that runs on Raspberry Pi boards, Orange Pi Lite SBC, Amlogic TV boxes, and other devices. But considering many people may already an older, perfectly working smartphones at home, FeelFree (Filip) decided to create the Octo4a project that install an Octoprint server on Android smartphones. It makes perfect sense since many smartphones come with a USB OTG interface that can connect to the 3D printer for control, while the touchscreen display is used for the user interface, and the camera to monitor your prints. SSH could be used to access the phone Octoprint server and change the settings manually. You can access the source code and APK files on Github. You’ll need to enable third-party apps in the settings before installing the app in order to install Octoprint on the phone. The only required permission is storage, except if you’d like […]

Sipeed LicheeRV – A $16.90 Allwinner D1 Linux RISC-V board

Finally! There’s now a much more affordable Allwinner D1 RISC-V Linux board thanks to Sipeed LicheeRV Nezha CM SBC sold for $16.90 and up on Aliexpress, that’s much cheaper than the $100 asked for Nezha SBC, although still not incredibly cheap as we’ll see from the specifications below. Sipeed LicheeRV is actually both a board and a system-on-on-module with an edge connector, and is equipped with 512MB DDR3, a USB-C OTG port, a MicroSD card socket, and an SPI display interface. The dual M.2 edge connector can be plugged into a carrier board, and they will be a “86 Box” (86x86mm) for HMI display that can be used for home automation. Sipeed Lichee RV specifications: SoC – Allwinner D1 single-core XuanTie C906 64-bit RISC-V processor @ 1.0 GHz with HiFi4 DSP, G2D 2D graphics accelerators Memory – 512MB DDR3 memory @ 792 MHz Storage – MicroSD card slot Video – […]

Phytium D2000 ARMv8 Mini PC runs Linux, supports gaming with Box64 emulator

Dragonbox is now taking pre-orders for a “Phytium D2000 ARMv8 Mini PC” with an octa-core 64-bit Arm processor, 16GB RAM, a 512GB NVMe, and an AMD Radeon RX550 GPU that makes it powerful enough to play older PC gaming like Crysis through Box64 x86_64 emulator, the 64-bit version of Box86 x86 emulator compatible with Raspberry Pi and other 32-bit Arm platforms. If the Dragonbox name sounds familiar, it’s because that’s the community that developed the Pyra handheld Linux game console/PC, except now they are offering a mini PC based on Phytium D2000 processor based on the same FTC663 Armv8 cores as found in the earlier Phytium FT2000/4 processor, with both Pythium SoC specifically designed for desktop PCs, contrary to most other Arm SoCs on the market. Phytium D2000 mini PC specifications: SoC –  Phytium D2000 ARMv8 octa-core custom Armv8 (FTC663) desktop processor @ 2.3 – 2.6 GHz with 8MB L2 […]

Photon Mono X resin 3D printer review with Wash and Cure Plus Machine – Unboxing and First Prints

Hey, Karl here. Today we are going to unbox and take a look at Anycubic’s Photon Mono X resin 3D printer and Wash and Cure Plus machine. The Mono X is what I would consider a medium size resin 3D printer that boasts a 192x120x245 build volume. Mono is included in the name because they have changed to a mono screen. They say there are 2 advantages when using a mono screen. 1 the screen lasts longer compared to an RGB screen and 2 it allows more light through allowing for faster prints. I won’t go into much detail as I believe most people are aware of this 3D printing method. In summary, UV reactive resin is cured layer by layer until a model is printed. The typical layer height of .05mm vs a typical .2 layer height for FDM printing allows for high detail printing and the layers are […]

WinnerMicro W806 240 MHz MCU finds it way into a $2 development board

I’ve just been notified about an inexpensive board (HLK-W806) based on WinnerMicro W806 32-bit XT804 (XuanTie E804) microcontroller clocked at up to 240 MHz and equipped with 1MB flash and 288KB RAM. XuanTie is the microcontroller family from Alibaba’s subsidiary T-Head Semiconductor, notably XuanTie RISC-V cores, but I’ve just learned not all XuanTie cores are based on the RISC-V architecture, and as we’ll see below, Xuantie E804 core appears to be based on the C-Sky architecture. It may still be interesting, as it’s in the STM32 board price range (pre-2020), but with a much higher frequency, so let’s have a look. HLK-W806 development board specifications: MCU – WinnerMicro W806 32-bit XT804 microcontroller @ 240 MHz with 1MB Flash, 288KB RAM, FPU, DSP, crtypto engine Expansion – 2x 24-pin headers with (based on MCU specs) 1x SDIO host with support for SDIO 2.0, SDHC, MMC 4.2 1x SDIO device up to […]

ODROID-N2+ review with Ubuntu 21.10 using Wayland and Panfrost

ODROID-N2+ was launched in July 2020, but I only got the Amlogic S922X Rev C SBC recently with Hardkernel wanting me to test their latest Ubuntu 21.10 image with the Panfrost open-source GPU driver. ODROID-N2+ Kit Unboxing Let’s start by checking out the kit I received from the Korean SBC manufacturer. The package includes ODROID-N2+ single board computer fitted with a 32GB eMMC flash module, a 12V/2A power supply with an EU plug adapter, an 80mm fan kit, and a USB 3.0 to eMMC reader. ODROID-N2+ is now only available with 4GB RAM, as the old ODROID-N2 with 2GB was deprecated, and we get four USB 3.0 ports, HDMI 2.0 video output,  Gigabit Ethernet networking, and a 40-pin GPIO header with the board cooled by a larger heatsink attached to the bottom of the board. Fan installation, first boot, and system information As we’ll see below the fan is not […]

Linux 5.15 LTS release – Main Changes, Arm, RISC-V and MIPS architectures

Linus Torvalds released Linux 5.15, an LTS version, this past Sunday: It’s been calm, and I have no excuse to add an extra rc, so here we are, with v5.15 pushed out, and the merge window starting tomorrow. Which is going to be a bit inconvenient for me, since I also have some conference travel coming up. But it’s only a couple of days and I’ll have my laptop with me. Sometimes the release timing works out, and sometimes it doesn’t.. Anyway, the last week of 5.15 was mainly networking and gpu fixes, with some random sprinkling of other things (a few btrfs reverts, some kvm updates, minor other fixes here and there – a few architecture fixes, couple of tracing, small driver fixes etc). Full shortlog appended. This release may have started out with some -Werror pain, but it calmed down fairly quickly and on the whole 5.15 was […]
