Baochip @baochip.com · 14/07/2026A version of the BIO core has been taped out and will be on the @wafer.space run 2! Thanks to Deepak Sharda (twitter: x.com/deeempak / website: lut4.com) for doing the heavy lifting of porting a version of the Baochip BIO core to this process! Full design available at github.com/dpks2003/bio... 1122
Baochip @baochip.com · 01/06/2026The Baochip-1x is IR-inspectable. But, how does one read chips, and what does it even mean? Here's a blog post put out by @bunnie.org that helps make sense of the Baochip-1x SRAM macros, and its implications for trusted boot: www.bunniestudios.com/blog/2026/on... 2164
Baochip @baochip.com · 28/05/2026Baochip is proud to be an inaugural member of the Pavona consortium. It's a strong step towards making secure, open source silicon broadly available.

Baochip @baochip.com · 20/03/2026One of my favorite features about the Baochip-1x is the BIO. I've just put out a post explaining the origin of the BIO, including a comparative study against the PIO and some examples of how to use it. www.crowdsupply.com/baochip/daba... 0183

Baochip @baochip.com · 07/03/2026Production tester for the dabao is ready! 100% of boards run through a test where every I/O is toggled, both buttons are pressed, serial ports tickled, and an initial OS image is loaded. Voltages and currents are also checked. The test checks for errors in soldering, and/or faulty components. 3392

Baochip @baochip.com · 31/01/2026Here's what a socket looks like for chip scale packages. Each one is custom made for a given chip package. A couple samples of the 0.4mm pitch Baochip CSP devices are laid out on the lower rim of the socket for size reference. 2333
Baochip @baochip.com · 23/01/2026Behold the graveyard of Baochips! Security testing is hard, after the chips are locked the only recourse is to desolder and replace them when a test goes wrong or an attack sensor is tripped. On the upside, I'm getting really good at reworking CSPs. 1170

Baochip @baochip.com · 01/12/2025It's nice to be able to simulate your constant-time code and prove to yourself that you got it right. Pictured is a simulation of AES chaffing, where fake and real data are computed in a random order. The timing of fake->real and real->fake has to be identical in order to mask power side channels. 140

Baochip @baochip.com · 17/11/2025Backside IR image of the chip! The Baochip-1x is packaged specifically to enable you to verify that you've got the correct chip, and not a fake or a substitute part (see bunnie.org/iris for how). The final chip will have part numbering that overlaps the memory array on the lower third of the chip. 080
