Wiser wireless-to-serial kit eases the debugging and programming of embedded devices (Crowdfunding)

WiSer wireless to serial kit

WiSer is a wireless-to-serial communication kit comprised of a USB dongle (WiSer-USB) and a USB TTL debug board (WiSer-TTL) – both built around an ESP32-S2 microcontroller – that allows users to establish a P2P wireless connection between a host computer and a development board or sensor. It works like a typical USB to TTL debug board except it operates over WiFi, and it’s especially useful to debug code, update firmware, log data, or transfer files without a USB cable or even a Wi-Fi router since the connection to peer-to-peer.  It looks especially useful when the host and DUT are too far apart, and my review samples are often on another table around 1.5m from the nearest USB port of my laptop, so I could see some use for it myself… WiSer specifications: Wireless SoC – ESP32-S2 Wi-Fi (and Bluetooth) microcontroller USB – 1x USB Type-C port providing a virtual serial […]

FOSDEM 2024 schedule – Open-source embedded, mobile, IoT, robotics, RISC-V, etc..


FOSDEM – which stands for Free and Open Source Software Developers’ European Meeting – is a free-to-participate event where thousands of developers meet in Brussels on the first week-end of February to discuss open-source software & hardware projects. FOSDEM 2024 will take place on February 3-4 with 880 speakers, 818 events, and 66 tracks. Although I won’t attend, I’ve created a virtual schedule like every year with sessions most relevant to the topics covered on CNX Software from the “Embedded, Mobile and Automotive” and “Open Hardware and CAD/CAM” devrooms, but also other devrooms including “FOSS Mobile Devices”, “ Energy: Reimagining this Ecosystem through Open Source”, “RISC-V”, and others. FOSDEM Day 1 – Saturday, February 3, 2024 10:30 – 10:55 – Screen Sharing on Raspberry Pi 5 Using VNC in Weston and Wayland with the Yocto Project and OpenEmbedded by Leon Anavi In 2023, embedded Linux developers received eagerly awaited news: […]

AirGradient ONE Kit Review – An open-source indoor air quality monitor

airgradient one ready to work

The product we are reviewing today is the “AirGradient ONE” air quality monitor kit which is an updated version of the earlier AirGradient air quality monitor. The device is equipped with sensors from Sensirion and Plantower, allowing it to measure many air quality parameters such as CO2, PM2.5, TVOCs, NOx, temperature, and humidity. It is an indoor air quality monitor that is both open-source software and open hardware. This means that the Arduino source code, schematic diagrams, PCB, and 3D models of the enclosure are available to developers. AirGradient ONE DIY Kit Unboxing The device was packaged within a cardboard box, with a greeting card from the manufacturer. The card features a QR code linking to a webpage with the installation guide. Since I requested the Kit version (there’s also a fully assembled model), some sensors were not pre-assembled and they were well-packaged in separate seals. The main PCB was […]
