I do some FOSS work with bootloaders and would love a cheap setup where I could leave boards running and have remote access to their UART/SPI/power.

Occasionally I need to be able to get physical access to it too.

I use esp32 for the remote UART/SPI, but don't really have a good setup for keeping a few projects tidy, and with the ability to move it from its remote location (a bookshelf) to my desk for physical access.

Does anyone know of any cheap and dense way to store these projects/boards?
