My single board server with LattePanda Sigma

This project wasn't my initial plan but evolved from my longstanding interest in single-board computers for personal tech projects like a home server or in-car PC. One day, after buying a touch screen, I contemplated creating a DIY tablet using a single-board computer. I considered various options, including Android-based boards from Khadas. However, I stumbled upon the LattePanda Sigma, which impressed me with its powerful specs and Atmega controller I/O header for DIY versatility. I bought it and tested it extensively with my 4K TV, enjoying movies and games with a PS5 controller.

Simultaneously, I was upgrading my old personal computer and decided to start with peripherals. Recalling a YouTube tutorial, I attempted to connect an external GPU to the Sigma. I acquired a special NVME adapter, a Geforce RTX4070 Ti, and a Deepcool power supply. This led to the creation of my everyday desktop setup for both work and leisure.
