- Baochip-1x is an open-source, inspectable system-on-chip (SoC) with an open bootloader and design source.
- Features include multiple cryptography accelerators, key stores, true random number generation, and hardware attack countermeasures.
- The Dabao Evaluation Board is a cost-optimized 2-layer board with Baochip-1x, aimed at embedded developers and hobbyists.
- Baochip-1x includes a 700 MHz quad-core PicoRV-powered I/O coprocessor (BIO) for versatile I/O applications.
- The BIO is 100% open source and patent-free, allowing for customization and use in other projects.
- IRIS inspection enables users to verify the chip's integrity by viewing the actual transistors.
- Baochip-1x is suitable for security-critical applications like password managers and authenticators.
- The Dabao board compares favorably with other development boards in terms of security, speed, and open-source features.
- Manufacturing involves Crossbar as the wafer provider, with two die revisions (-A0 and -A1).
- Global instability is the primary risk to delivery, but the design and supply chain are established.
