The Baochip-1x is an SoC with enhanced open source and security features. Fabricated in TSMC22ULL, it has a 350MHz Vexriscv RV32-IMAC CPU with Sv39 (virtual memory) support, along with 2MiB of integrated SRAM and 4MiB of integrated RRAM. RRAM is non-volatile memory analogous to FLASH.

The full part number is BAO1X2S4F-WA, but the part is referred to as the “Baochip-1x” or the “bao1x” interchangeably.

Automated provisioning of secure boot and encryption for Raspberry Pi devices

What Problem Does This Solve?

Imagine you need to prepare 100 Raspberry Pi devices for your business.

Each device needs:

  • A secure boot system (so only your software can run on it)

  • Encrypted storage (so your data is protected)

  • Your custom operating system installed

  • Security keys programmed correctly

Without this tool, preparing each device manually is time-consuming and error-prone. Each command must be executed precisely. A single mistake requires restarting the entire process.

This tool automates the entire provisioning workflow. Connect a device, and the tool handles all configuration steps automatically. Typical provisioning time is approximately 3 minutes per device (for a 2.6GB OS image).

This X1200-c1 case is designed for the raspberry pi 5 X1201 ups shield only, it can fully accommodate the X1201 and the Raspberry Pi 5, with space reserved on the top for mounting the Raspberry Pi 5 Pip boards, such as the X1001, X1000, X1004, X1003 and M901 etc.

Note: Due to the height limitations of the housing, although the X1201 also supports external switch, but no holes of 12 mm in diameter have been provided for the mounting of an external momentary switch.
