ESP32-S31 dual-core RISC-V SoC is getting official Linux support. cnx-software.com/2026/08/22/… Espressif Systems has released a developer preview of the ESP Linux BSP for the ESP32-S31 based on buildroot and Linux 6.18. We explain how to get the code and build the image in the link above. Two community projects are also being worked on: one using Linux 6.12 and the other Linux 7.1.

Mozilla — finally — adds Web Serial support to Firefox, starting in Firefox 151. hackster.io/news/mozilla-fin…

Mozilla — Finally — Adds Web Serial Support to Firefox, Starting in Firefox 151

Web apps can now request access to serial ports — including USB devices — in Firefox, just like in Chromium-based browsers.

It turned out that @Harman or @NabuCasa have made a native app for Audi MMI. I immediately noticed two super cool features: 1. A mode with big buttons which works while driving and a native mode which opens the web UI. 2. HA voice can be set as default voice assist in the car.

QuickPort Terminal on iPad is amazing.🤩 I2C master feature is great for testing sensors, plotting and logging data! #QuickPort #iPad #iPadOS #EmbeddedSystems #Hardware #UART #I2C #SerialConsole #RP2040

Quickport dongles have arrived🚀 Here is an example of reading @adafruit SHT-C3 sensor from the #iOS app! I2C drivers are stored in the App and #rp2040 is only processing raw transactions ⚡️

A sneak peek at the I2C features of QuickPort. Most of the logic is implemented in the App - drivers, data conversion, etc. The app basically sends read and write commands to the RP2040 over WS in a way that latency from network doesn't affect data integrity!🥁

QuickPort Dongle custom bootloader is ready!🚀 The bootloader adds support for A/B FOTA and generates a cryptographic device identity from the QSPI flash's SN, verified by the cloud backend🔒 iOS app successfully verifies and updates the devices⚡️ #rp2040 #iOS #fota #firmware

QuickPort Terminal is now available on the App Store! This is a HUGE milestone 🚀🚀🚀

🚀 QuickPort is submitted for App Store review — the first real UART terminal made for iPhone. If Apple says yes on the first pass, that’s huge 🤞 And the timing is perfect: QuickPort Dongle assembled PCBs arrive early next week. UART + iOS. Finally ❤️

Today is a big day for my iOS UART Dongle! PCB manufacturing at @JLCPCB has started and my Apple Developer account is ready!

Progress update 🚀 PCB design is almost ready! I printed the PCB and case on a 3D printer to physically verify the PCB fit and enclosure dimensions. All ports line up ALMOST as intended. This step already caught things CAD alone wouldn’t. Hardware first, surprises later avoided.

In case you wonder what is the qwiic connector for - the device will support reading various I2C sensors. The iOS app itself can log and plot sensor readings 🌡️📈

I started working on USB-to-UART bridge for iOS! RP2040 + TinyUSB = USB-Ethernet adapter that creates a direct link between iOS dev and any UART device. Native SwiftUI app connects via WebSocket to send/receive serial data in real-time. No Wi-Fi needed. #rp2040 #ios #swiftui

After some requests in r/embedded I have released versions for Windows and Linux for the Serial Console Pro. Any feedback will be appreciated: github.com/miroslavpetrov/Se…

I was very frustrated by the fact there isn’t a nice serial terminal app for MacOS. So I have decided to make one and release it as open source software. This is my Christmas gift to everybody who uses MacOS and needs a feature-rich serial terminal app. github.com/miroslavpetrov/Se…

I have finally got my hands on @M5Stack Tab5! Using @lvgl_io and ESP IDF I have developed a @home_assistant companion device that fetches all HA entities and groups them by type. The built-in web UI allows for entity filtering and friendly name assignment! More to come soon🚀

This is a project I wanted to start a long time ago. Using @seeedstudio Sensecap indicator, @esphome_ and @home_assistant I have created an amazing climate controller for my office. Next steps are to integrate lights, blinds and 3d printer status 🎉
