New #opensource hardware evaluation board with NXP i.MX8MP @ 1.6GHz and 4GB RAM System on a Module (SoM) by OLIMEX Ltd

I was happy to port the #opensource RAUC software over the air update solution with Yocto Project to Radxa Rock Pi 4 Model B. Now with the new layer meta-rauc-rockchip other Rockchip devices can be ported easily.

RAUC open-source OTA firmware update project for #embeddedLinux now supports Rockchip targets starting with Radxa Rock Pi 4 SBC. #yocto #embeddedsoftware cnx-software.com/2024/06/29/rau…

I've brought a big bag of open hardware launched on Crowd Supply with me to #HOPE2024, including Precursor by bunnie & Sean Cross, Sensor Watch and an Open Book prototype by @[email protected] and the upcoming Anwaar by بلبل يوسف. Come find me near the registration desk!

☀️ An opto-isolator uses light to transfer electrical signals between two isolated circuits ⚡ ⚠️ My new video shows how to design PCB with EL817 optocoupler to read 12V from 3.3V tolerant GPIO. Thanks to PCBWay for the prototypes! youtu.be/hTAVO4u1d1s #opensource

I am sure CrowdStrike congratulates all system administrators on System Administrator Appreciation Day :) :) :) #SysAdminDay

📄 The 2nd part of the article about #opensource software updates is now out on the Konsulko Group website 🔍 It explores #Mender A/B updates on embedded #Linux devices using Yocto Project and OLIMEX Ltd i.MX8MP SoM and evaluation board konsulko.com/ota-updates-im…

🔌 🤝 Demonstration of USB-C Power Delivery (PD) negotiation with an Arduino sketch over I2C and adafruit industries HUSB238 breakout board 🎥 📺 My video with details: youtu.be/AnPnULC6RMI #opensource #arduino

What’s common among all these old boards? 💡 They’re powered by Allwinner (sunxi) SoC: OLIMEX Ltd with A20 & A10, OrangePi with H3 & H2 🔧 You can build custom #Linux distributions for all of them using meta-sunxi and Yocto Project 🔄 Perform software A/B updates with RAUC

🎥 My new video explores different voltages with USB-C PD ThinkPad and #RaspberryPi power supplies using CYPD3177: ✅ Arduino sketch for I2C negotiation to CY4533 ✅ Hardware voltage selection CY4533 ✅ Prototype USB-C trigger PCB thanks to PCBWay youtu.be/tAVDUL7oPl4?si…

🌐 Wire #RaspberryPi Pico or Pico 2 to the Internet 🛠️ Thanks to PCBWay for providing the prototypes of the board I designed in #KiCad 📹 The #Arduino sketch is available at #GitHub and the exact steps are in the video youtu.be/4rrMr-6640o?si…

🔧 Excited to show my new video how to set up offline speech-to-text on a #RaspberryPi 5 with #Python3 🎙️ Featuring my #opensource ANAVI Dev Mic with RP2040 MCU 📜 Watch demo and get the full code on GitHub with OpenAI Whisper - no internet required youtu.be/XzCWIGtRq4g

🚀 A few weeks ago, #RaspberryPi dropped their 2nd microcontroller, the RP2350, along with the Raspberry Pi Pico 2! 🔧 Seeed Studio has already integrated it into the new XIAO RP2350 module. 📦 Check out my unboxing video for all the details: youtu.be/iiGXlesPuWA

It's official!! We're going to Edinburgh, Scotland for 2025!! We're so excited to make it over the pond and get to see all the exciting open source work happening over there! We are also now accepting proposals, hit up 2025.oshwa.org to learn more.

🚀 #RaspberryPi provides C/C++ SDK for Pico that runs on Raspberry Pi SBC with #Linux 📽️ My latest video shows it with the #opensource "Microphone Library for Pico" on my open source hardware computer microphone ANAVI Dev Mic with Seeed Studio XIAO RP2040 youtu.be/x1zH7MOIIA8

With open source through hell and high water. Despite the bad weather I arrived safe in Vienna for Open Source Summit 2024. #linux #OSSummit #opensource
