Although the JH7100 is powerful, but many applications do not require 8GB memory
Not all projects have a lot of memory usage, I 'm suggest for produce 4GB and 8GB two versions of VisionFive SBC to reduce price of the board.
Since we have limited amount of production this time, we are not going to use 4GB in JH7100 board. We will take that in consideration for our next generation board with JH7110, which is planned to be produced Q3 - Q4 next year.
Thank you for mentioning this valuable suggestion.
BTW, we are also offering sponsorship program. If your project is open sourced, you could apply to this program. The board could be free
