  "textContent": "An open-source hardware board usually features a closed-source microcontroller or processors, but the Dabao evaluation board goes further with the open-source Boachip-1x MCU, whose RTL files are available. It’s also manufactured in such a way that it is inspectable with the Infra-Red, In Situ (IRIS) technique, so users can look at the silicon and confirm they’ve got the right chip in a non-destructive way. Baochip-1x is a “general-purpose” microcontroller with a 350 MHz Vexriscv RV32-IMAC CPU core, a BIO accelerator for I/Os with four 700MHz PicoRV RV32-EMC CPU cores, 4MB of ReRAM, 2MB SRAM, a USB interface, various other I/Os, and hardware secure elements such as cryptography accelerators, key stores, one-way counters, true random number generation, and hardware attack countermeasures such as glitch sensors and a security mesh. The Dabao board itself is pretty basic with the microcontroller, two 16-pin headers for I/Os, a USB-C port for power and programming, [...]\n\nThe post Dabao board features open-source hardware Baochip-1x RISC-V MCU (Crowdfunding) appeared first on CNX Software - Embedded Systems News.",
