Dabao has launched!!!
Open hardware, firmware, software from @bunnie !
https://www.crowdsupply.com/baochip/dabao/updates/our-campaign-has-launched
Today marks the start of the Dabao campaign. If you're interested in open source hardware, security, or trust, I'm offering you a chance to order some of the first evaluation boards for a mostly-open, security-oriented microcontroller. Dabao is an evaluation board for the Baochip-1x SoC, a microcontroller that raises the bar on inspectable hardware, bringing you a system-on-chip (SoC) that you can check from the silicon all the way to the software.
If you missed my talk with Xobs at #39c3, the recording is now up: https://media.ccc.de/v/39c3-xous-a-pure-rust-rethink-of-the-embedded-operating-system
Learn about Xous, the pure-Rust OS we've been working on, and the Baochip-1x, a full custom silicon chip that will soon be available, purpose-built to run Xous!
Xous is a message-passing microkernel implemented in pure Rust, targeting secure embedded applications. This talk covers three novel aspe...
I'll be presenting some of my latest work on Xous & Baochip with @Xobs at #39C3 on Day two, 11PM room One:
Hope to see you there!

The TL;DR is that Baochip is a "mostly-open" RTL SoC in 22nm TSMC, purpose-built for Xous and expressly packaged for IRIS inspection. It packs in five RISC-V CPU cores (one Vexriscv CPU at 350MHz, and four PicoRV's at 700MHz), 2MiB on-chip SRAM and 4MiB on-chip RRAM (basically FLASH).
I'm aiming to have the chip broadly available by early 2026. Right now I have first silicon. You can follow development & ask questions on the Baochip discord at https://discord.gg/yesbcPF9Xy
Sorry, no website yet - I suck at marketing - but hey, at least the source code is up!
Nice! thanks for sharing that! You even got the standard cell area to resolve pretty nicely.

I used a 60degree, 1064nm power LED from Aliexpress as a light source, and imaged it using an RPi HQ camera with the IR filter removed mounted to our stereo inspection microscope.
Had the pleasure of speaking with Sera Evcimen for her "Builder's Circle" podcast to talk about open hardware & hardware startups.

Ironically I use neither of those services but then again I live under a rock as far as the modern Internet goes.
🚨 New Episode Drop! 🚨 I had the absolute honor of hosting bunnie huang; the voice, mind, and rebel spirit behind hacking hardware on The Builder Circle™: The Hardware Startup Success Podcast. 💥 Bunnie has shaped the world of open hardware more than most people realize. From challenging closed ecosystems to building tools that democratize innovation, his work not only changed how products get built… but who gets to build them. In this episode we go deep on: ⚙️ What “open” actually means; beyond buzzwords 🔐 Why openness can become a competitive moat 📦 What companies should reconsider about IP strategy 🛠️ The messy truth of making hardware accessible If you care about hardware, accessibility, or the future of making physical products open, this is the one to listen to. 🎧 Listen here: https://lnkd.in/gMFHrYZY #hardware #openhardware #innovation #electricalengineering #deephardware #thebuildercircle #podcast #hardwarestartups
Heading to Amsterdam to speak at Hardwear.io NL this Wed! I’ll talk about high assurance silicon and the practical steps required to achieve strong verification and transparency.
In my talk, I'll be highlighting my latest project: Baochip, a 22 nm MCU I’ve been building to raise the bar on assurance for everyday devices.
