This project is fully opensource hardware (raspberry pi inside).  Full part list of commonly available hardware components complement a github that includes not only build instructions but all the base code needed to run full Ethereum blockchain (L1+L2) interaction via the device.  The code is presented simply with an unlimited amount of programmable options due to the many buttons available on the base device and the full power of many open source python modules for any possible integration.  Additional display screens in terms of size and button configurations are available and easily adapted to work with the device.
