ESP32 may soon get an open-source WiFi MAC layer

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)

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: […]

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

apt install ttf-mscorefonts-installer
./UIFlow.Server.Desktop

1 2	apt install ttf-mscorefonts-installer ./UIFlow.Server.Desktop

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

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 […]

Youyeetoo X1 x86 SBC Review – Part 2: GPIO, UART, I2C, SPI, NFC, PoE module, and power consumption

The Youyeetoo X1 x86 single board computer (SBC) with an Intel Celeron N5105 Jasper Lake CPU differs from a typical Intel or AMD mini PC by its range of IOs including SPI, I2C, UART, NFC connectivity, and support for PoE module that you won’t find in a typical computer, and that’s what we will test in the second part of the X1 SBC review along with power consumption. The Youyeetoo X1 SBC is also different from Arm-based single board computers since we can just install any x86-compatible operating system by ourselves, and w don’t need to flash a board-specific image like we would do with Arm SBCs and peripherals such as SPI, I2C or UART may be or may not usable immediately due to lack of supported drivers. We’ve already installed Ubuntu 22.04 on the Youyeetoo X1 in the first part of the review, so in the second part, we’ll […]

Lenovo Chromebox Micro fanless mini PC runs ChromeOS, targets digital signage applications

There’s a new type of Chromebox in town with the Chromebox Micro with a form factor very similar to the MeLE Quieter4C we’ve just covered, but running Chrome OS instead and designed to be mounted to the back of a display. The Lenovo Chromebox Micro is the first device of this type that I’ve seen. The fanless mini PC is based on an Intel Celeron N4500 dual-core processor with 8GB RAM and 32GB eMMC flash and mostly targets digital signage and interactive retail kiosks. Lenovo Chromebox Micro: SoC – Intel Celeron N4500 dual-core processor @ 1.1GHz / 2.8GHz (Burst frequency) with Intel UHD graphics; 6W TDP System Memory – 8GB Storage – 32 GB eMMC flash Video Output – 1x HDMI port Audio – 1x audio jack, digital audio via HDMI Networking – Gigabit Ethernet RJ45 port USB – 2x USB Type-C ports, 2x USB Type-A ports Misc – Power […]
