Radxa Zero 3W SBC – Rockchip RK3566 SoC, 8GB RAM, WiFi 6 in Raspberry Pi Zero 2 W form factor

RADXA Zero 3W

More Raspberry Pi Zero 2 W lookalikes are coming to market, as after the Allwinner H618-based Orange Pi Zero 2W, the Radxa Zero 3W has now been introduced with a 1.6 GHz Rockchip RK3566 processor and up to 8GB RAM, plus WiFi 6 and Bluetooth 5.4 connectivity, which makes it one of the most powerful Arm Linux SBCs in the compact Raspberry Pi Zero form factor. The board also comes with an optional eMMC flash with up to 64GB capacity, a microSD card, a micro HDMI port, two USB Type-C ports, a MIPI CSI camera connector, and of course, the usual 40-pin Raspberry Pi GPIO header. Radxa Zero 3W specifications: SoC – Rockchip RK3566 CPU – Quad-core Arm Cortex-A55 processor @ 1.6 GHz (Note the RK3566 is usually clocked at up to 1.8 GHz but may have been underclocked here due to heat issues at the higher frequency as the […]

NORVI ESP-HMI-5C ESP32-based HMI features a 5-inch resistive touchscreen display

ESP32-S3 5-inch HDMI display

NORVI ESP32-based human-machine interface (HMI) solution features a 5-inch LCD with a resistive touchscreen driven by an ESP32-S3 wireless module and support for the LVGL library. NORVI previously brought us some headless ENET industrial controllers including some with Ethernet beside the WiFi connectivity built into the ESP32 microcontroller, but the NORVI HMI device is the first product from the company with a proper display suitable for HMI applications. NORVI HMI (ESP-HMI-5C) specifications: Wireless module ESP32-S3-WROOM32-1-N16R8 MCU – ESP32-S3 dual-core LX7 microprocessor @ up to 240 MHz with Vector extension for machine learning, 512 KB SRAM Memory – 8MB octal SPI PSRAM Storage – 16MB flash Connectivity – WiFi 4 and Bluetooth 5 with LE/Mesh PCB antenna Storage – MicroSD card slot (SPI interface) Display – 5-inch LCD Display with Resistive Touch Audio – Built-in Buzzer Communication interfaces – Ethernet (W5500) and RS485 I/Os 4x digital inputs – Range 18V to 32V […]

ESP32 may soon get an open-source WiFi MAC layer

ESP32 open-source WiFi MAC driver

Most, if not all, WiFi hardware relies on closed-source binary blobs including ESP32 wireless MCU, but there’s now work underway to reverse engineer a WiFi MAC layer for the ESP32 to make it a truly open-source platform. Espressif ESP32 wireless microcontrollers already have an open-source framework (ESP-IDF) and toolchain, people can customize the code to some extent, but this excludes the wireless bits (Wi-Fi, Bluetooth, low-level RF functions) that are distributed as closed-source precompiled libraries integrated into the firmware. There were some efforts to provide an open-source stack for the BL602 chip but it never went anywhere, and the ESP32 may become the first target with an open-source driver without any blobs, excluding FPGA-based projects such as OpenWiFi. The early-stage implementation currently supports the following features: Sending WiFi frames Receiving WiFi frames Send an ACK packet as a reply to packets that are sent to the ESP32 Connect to an […]

Tokay Lite – A battery-powered no-code AI camera based on ESP32-S3 WiSoC (Crowdfunding)

Tokay Lite ESP32-S3 no-code AI camera

Maxlab’s Tokay Lite is an OHSWA-certified AI camera based on ESP32-S3 WiFI and Bluetooth SoC that can be used for computer vision (e.g. facial recognition & detection) and robotics applications without the need to know programming languages since a web interface is used for configuration. The WiFi and Bluetooth AI camera also features night vision with four IR LEDs, an IR cut filter, light and PIR motion sensors, a 20-pin expansion connector with SPI and UART, support for an external RTC, and can take power from USB-C or a LiPo battery. Tokay Lite specifications: Wireless module ESP32-S3-WROOM-1 MCU – ESP32-S3 dual-core LX7 microprocessor @ up to 240 MHz with Vector extension for machine learning, 512 KB SRAM Memory – 8MB PSRAM Storage – 8MB SPI flash Connectivity – WiFi 4 and Bluetooth 5 with LE/Mesh PCB antenna Certifications – FCC/CE certification Camera OV2640 camera sensor (replaceable) via DVP interface Image Capabilities: […]

Renesas’ first 32-bit RISC-V CPU core delivers up to 3.27 CoreMark/MHz

Renesas has recently announced its first homegrown 32-bit RISC-V CPU core based on open-standard instruction set architecture (ISA).

Renesas has recently announced its first homegrown 32-bit RISC-V CPU core based on the open-standard instruction set architecture (ISA). This CPU core is compatible with Renesas’ e2 studio IDE and supports other third-party IDEs for RISC-V MCUs. According to Renesas, the CPU achieved a remarkable 3.27 CoreMark/MHz performance outperforming similar RISC-V architectures in this category. RISC-V, an open ISA, is rapidly gaining popularity in the semiconductor industry. Many MCU providers have formed joint investment alliances to expedite their RISC-V product development. Previously, Renesas released two CPUs developed by Andes Technology Corp: the R9A02G020, an ASSP EASY MCU for Motor Control, and the R9A06G150, an ASSP EASY MCU for Voice HMI, both based on RISC-V. Additionally, they have introduced the RZ/Five, a Linux-capable 64-bit RISC-V microprocessor family, and RH850/U2B, an automotive System on Chip (SoC).  However, with the release of their new CPU, Renesas independently enters the RISC-V market, highlighting their […]

Add WiFi connectivity to older USB printers with Orange Pi 3G-IoT-A and UoWPrint print server

Orange Pi 3G-IoT-A printer server

I previously used an inexpensive CHIP board as a Linux printer and scanner server for the Canon MP250 USB multi-function printer. It took a while to make it work with a long list of instructions and even then the scanner function was not working very reliably. ValdikSS’s UoWPrint driverless printing and scanning server aims to simplify the process for older USB printers and also supports AirPrint and Mopria standards over WiFi. The older Orange Pi 3G-IoT-A board was the hardware of choice for this project due to its ultra-low price. The resulting product enables users to convert their old USB printer (or MFP) into a WiFi printer/MFP and print and scan without drivers from Windows, macOS, and Linux, as well as mobile operating systems such as iOS/Android. ValdikSS told CNX Software he spent a considerable amount of time backporting patches required to run modern Debian 12 to the kernel 3.2.67 […]

M5Stack releases local server implementations of UIFlow visual programming Web IDE

Visual programming local Web IDE

Visual programming is now a very popular method to teach programming to kids and M5Stack relies on UIFlow for their ESP32-based IoT development kit. Like most other companies, M5Stack provides either a Web IDE accessible from their server or a desktop program available for Windows, MacOS, or Linux, but the company has now released a local server implementation that allows users to run a Web IDE instance in their local network. The local server is available for Windows 11 x64, MacOS, Ubuntu 22.04, and Linux Arm (e.g. Raspberry Pi), so I downloaded the Ubuntu version to give it a try on my laptop. Somehow the Ubuntu release is full of Windows DLLs, but let’s ignore that for now, and the README.txt tells us to install one dependency and run the program as follows:

A window pops up letting us start or stop the server. It can be accessed with […]

MINIX Z100-0dB fanless Intel N100 mini PC supports 2.5GbE and WiFi 6 networking

MINIX Z100-0DB

Companies keep on releasing new Intel Processor N100 mini PCs, and the latest one is the MINIX Z100-0dB fanless mini PC with support for 2.5GbE and WiFi 6 networking, and dual display setups through two HDMI ports. The mini PC is said to support up to 32GB RAM, ships with up to 512GB NVMe SSD, and comes with the usual USB 3.2/2.0 ports, microSD card slot, and 3.5mm audio. The “0DB” name comes from the fact that it is a fanless system as shown on the top of the top device with the string “ZERO dB Cooling System”. MINIX Z100-0dB specifications: SoC – Intel Processor N100 quad-core Alder Lake-N processor @ up to 3.4 GHz (Turbo) with 6MB cache, 24EU Intel HD graphics @ 750 MHz; TDP: 6W System Memory – 4GB, 8GB, or 16GB DDDR4-3200, upgradable to 32GB Storage 128GB, 256GB, or 512GB M.2 SSD (PCIe Gen3 x4), upgradable […]
