Open-source, self-hosted Arduino, Raspberry Pi, and ESP32 simulator.
https://t.co/8w5RClkdYp

Like the Wokwi project, Velxio simulates popular development boards right in your web browser. But the difference is that the open-source project can be self-hosted, running on your own machine.

The project currently supports 19 boards and 48 components. Other highlights include support for multiple boards (e.g., Arduino connected to ESP32) and full QEMU emulation support for ESP32 and Raspberry Pi 3 (Linux).

ESP32P4、「360MHzデュアルコア+16MBフラッシュ+32MB RAM＋USB2 OTG対応＋H.264ハードウェアエンコーダー」で2,200円とかいう狂った価格設定しててヤバい
ヤバすぎてとりあえず2つ買った

.@Raspberry_Pi introduces 3GB RAM version of the Pi 4 for $83.75, and further increases pricing for 4GB+ RAM models.
https://t.co/kUO6P9ZIHA

That now means a Pi 4 4GB goes for $100 and a Pi 500+ Keyboard PC for a cool $410. Check the article for details.

Hi all
I'm currently no long employed by Linaro and am actively looking for work.
For the last few years I've been working on development of the Linaro Automation Appliance hardware, from prototype to final product.
If you are looking for Product Design Engeneer hit me up.

@byte_thrasher An even simpler approach. Connect the revision detect GPIO pin as an input and connect it to any other GPIO output [use this for anything] on the MCU. Toggle the output pin to determine which pin is connected to which. This is hardcoded and can't be changed accidentally.

[CIRCUITSTATE @circuitstate]

@byte_thrasher Dedicate an ADC pin and use a bunch of resistors on the board to tell the version. If can't have ADC pin, then add an oscillator on the board with programmable frequency with a bunch of, resistors, again. Capture compare the signal and determine the version.

@will_whang Wby do you leave that square opening on the PCB beneath the sensor?

It's actually OVER for any PCB milling software, they all SUCK! I put the nail in the coffin by adding v cuts and trace selection. Next up is double sided boards and alignment holes.

🤔KiCad 10 is here — how to keep your projects compatible?

NextPCB has developed the KiCad Version Converter to help engineers collaborate smoothly across mixed-version environments.

You can now downgrade schematic files, PCB layouts, symbol libraries and footprint libraries in seconds with this simple tool.

🔥Features:
• Freely downgrade KiCad files from 10, 9, 8 to version 9, 8, or 7
• Automatically remove elements that break compatibility
• Supports multi-file conversion
• No uploads — everything runs locally in your browser
• Includes a detailed change log for every conversion

Just merged my DSI driver for STM32H7 into Embassy.

Here’s a mock display using @ratatui_rs and mousefood rending into an SDRAM framebuf.

Open-source hardware @MicrochipMakes ATTiny1616 board that's about the size of a USB-C port.
https://t.co/Yc8VY3GCdM

The tiny AngstromIO board is powered via USB-C and features two RGB LEDs and solder pads for GPIO, I2C, UART, and UPDI interfaces.

The board is programmable with the Arduino IDE, but requires an external programmer board since the USB-C port does not carry data signals. "Dieu-de-l-elec" also designed a CH32V003 board whose design is shared in the same GitHub repo.
