Read-Only Offline Crypto Device Recipe - Hardware

< Back to Read-Only Offline Crypto Device Recipe

You will need the following items:

Raspberry Pi 400

The Raspberry Pi 400 is a compact self-contained computer built into a keyboard.


MicroSD Card

8GB or larger MicroSD card to store the operating system files. I am using a SanDisk Extreme 32GB - see here and here for some comparisons of these cards.


USB-C Power Supply

Raspberry Pi 15W USB-C Power Supply. Many USB-C laptop power supplies should also work with the Raspberry Pi 400.


USB-A or USB-C Mouse

Raspberry Pi Mouse, or USB-A or USB-C equivalent.


Monitor With Micro HDMI Cable

Computer monitor connected via a HDMI cable that plugs into one of the two Raspberry Pi 400 Micro HDMI ports:

If you have access to computer monitors with only HDMI plugs, you may want to consider something like a Micro HDMI to HDMI Adapter for Raspberry Pi 4:


Component Prices

Component AUD, in Australia
Raspberry Pi 400 149
32GB MicroSD Card 22
Power Supply 25
Mouse ~15
Monitor ~100

Separate Computer And Wireless Internet

You will also need a separate internet connected computer to install the Raspberry Pi OS software onto the MicroSD card, and a wireless internet connection for the initial installation of this Shamir39 device.



Alternatives

Raspberry Pi models 4 and B may also work. You may need a case, and a USB-A or USB-C keyboard.

Similar steps can be used to build this device on other platforms using the Ubuntu (or similar Linux) operating system.



{Summary, with table - 400 & alternatives }
