Here are the board details: https://www.nandland.com/goboard/introduction.html

Excellent board for beginners and open source projects.

Thank you.

We do not, in general, accept requests for new board definitions through issues in this repository. I suggest implementing support for this board yourself or finding someone to implement it, and submitting it as a pull request.

I ordered the Nandland Go board, and I will gladly write up and test the board definition for it once it arrives. Given that shipping might take about 4-5 business days (estimated Friday), I am estimating that to be for the next weekend.

Just a heads up, this issue can be closed since the merge of #164.
