Andrew “bunnie” Huang is a guiding light in the world of privacy-friendly, verifiable hardware, and has just concluded a successful Crowd Supply campaign with Dabao – an evaluation board for the Baochip-1x. This chip aims to standardize security-friendly practices across the tech industry, by opening up secure features that typically require steep prices and NDAs. It’s easy to inspect with infra-red in-situ (IRIS) imaging, and also sports a memory management unit (MMU) and a BIO (Baochip I/O) coprocessor. And the Dabao board is designed for flexibility and fun! Learn all about it in this casual interview, hosted by Hackster Pro Partner Alex Glow. 🛠 Join us live and drop your questions in the chat! 🔔 Follow Hackster.io for more hardware news, interviews, and tutorials Links: // Dabao on Crowd Supply: https://lnkd.in/gVjGehBJ // More about the BIO coprocessor: https://lnkd.in/ge9565bu // Hardwear.io talk, “Towards End-User Verifiable Silicon”: https://lnkd.in/gdH5ajtf // Hackaday Europe talk, “Seeing Through Silicon with IRIS Imaging”: https://lnkd.in/g5ydA43g // Previously on Hackster Café (Nov. 2020): https://lnkd.in/gv5ajpba
