@chiptronCZ In your ESP32 list and comparison, TWAI/CAN/CAN FD #canbus support is missing completely. The most of the #Espressif #ESP32 family members have standard CAN support. ESP32C5 is the first with CAN FD (2x), ESP32S31 CAN FD (2x) and ESP32H4 CAN FD (1x).

#Espressif has put out a rather unorthodox dev kit. Not a breakout board, but a funky little digital camera, complete with display and battery charger. (Lithium pouch cell not included for shipping reasons.) They're using their P4 as the main processor. No espressif board would be complete without an ESP32 for wifi and bluetooth, in this case an ESP32-C6.

The price mouser has it for is far too low and people like me are going to buy it just as a toy.

Docker for Microcontrollers? AkiraOS combines Zephyr RTOS with WebAssembly (WASM) applications

Docker for Microcontrollers? AkiraOS combines Zephyr RTOS with WebAssembly (WASM) applications

AkiraOS is a Zephyr-based embedded OS that runs sandboxed WebAssembly applications on microcontrollers and lets users deploy and update firmware OTA without reflashing. In other words, it's similar to Docker containers, but for microcontrollers. The open-source embedded platform separates the OS from the application. That means the firmware stays stable, while apps are independent .wasm binaries deployable over-the-air without touching the OS, and portable so a single binary works on ESP32-S3, nRF5x, or STM32 MCU boards. AkiraOS highlights: User space Up to 8 wasm apps can be installed Up to two apps can run at the same time Footprint: 50KB to 200KB per app Akiraz runtime - Custom WASM runtime App Manager UI Framework with 32 widgets Shell/console 18 API modules WebAssembly Micro Runtime (WAMR) - Two options: Interpreter or Ahead-Of-Time (AOT) compilation with 10 to 50x higher performance RTOS - Zephyr RTOS Scheduler Network stack HTTP for OTA updates

EKOS – An ESP32-S3 ePaper dashboard housed in an oak-aluminum enclosure (Crowdfunding)

Designed by StillFixing in Normandy (France), the EKOS is a local-first, low-power ePaper dashboard built around an ESP32-S3 SoC. It operates without any cloud dependency, subscriptions, or external accounts, offering full privacy, faster response times, and direct local control. The device comes in two variants: the EKOS Pure is a minimalist, non-touch version with two physical buttons for basic control, and the EKOS Sense adds a capacitive touch layer for smart home control, such as toggling devices, triggering scenes, or managing tasks. Both models feature a repair-friendly design with no adhesives, using four screws for assembly and a user-replaceable lithium-polymer battery. Additionally, the dashboard can be updated entirely over your home network without needing the internet. You can push data to the screen using a local API from a phone or PC, link it straight to Home Assistant, or use it to control other ESPHome devices around your house. EKOS

Ah yes, another day, another vomit of alphanumeric soup from #Espressif 🍜. Because who doesn't love drowning in an endless sea of #ESP32 acronyms while pretending to understand what an "ESPMatter SDK" is? 😏 Surely, this is the holy grail of tech innovation... or just a clever ploy to keep the engineers employed. 🤡

Wireless-Tag ESP32P4C61-TINY board combines ESP32-P4 and ESP32-C61 SoCs (Crowdfunding)

Wireless-Tag has launched a Kickstarter campaign for the ESP32P4C61-TINY, a compact open-source AIoT development board based on their WT01P461-S1 module, which combines ESP32-P4 (general-purpose) and ESP32-C61 (wireless) RISC-V SoCs. Like other ESP32-P4 boards, including the ESP32P4C5 Core Board, the M5Stack Stamp-P4, or ESP32-P4-Pi-VIEWE, this one also uses a separate SoC (ESP32-C61) for wireless connectivity. Additionally, it features built-in MIPI CSI and DSI for camera and display support, along with a microSD card slot for storage, making it suitable for AIoT and edge computing applications.

PCMFlow722 library enables two-way real-time HD voice over ESP-NOW with G.722 audio codec

https://fed.brid.gy/r/https://www.cnx-software.com/2026/05/30/pcmflow722-library-enables-two-way-real-time-hd-voice-over-esp-now-with-g-722-audio-codec/

PCMFlow722 library enables two-way real-time HD voice over ESP-NOW with G.722 audio codec

Tanaka Masayuki's PCMFlow722 library enables (half-duplex) two-way real-time HD voice over ESP-NOW on ESP32 boards with a speaker and a microphone, effectively transforming them into walkie-talkies. The library implements a G.722 wideband codec add-on for PCMFlow lightweight audio decode and PCM flow library for Arduino, which already supports uncompressed PCM, MP3, and FLAC audio codecs. PCM and FLAC take too much bandwidth over ESP-NOW, and MP3 is not suitable for real-time audio, so the legacy G.722 audio codec was selected instead. The keyword here is "HD voice," since two-way audio over ESP-NOW was previously implemented in projects such as Atomic14's esp32-walkie-talkie (5 years ago) and, more recently, the well-documented Adafruit ESP-NOW Walkie-Talkie project, but these typically rely on lower-quality G.711 audio or compressed audio. The PCMFlowG722 library and G.722 codec enable HD voice with "7 kHz audio at 16 kHz sampling using the same 64 kbps wire budget as G.711
