DGT Bluetooth e-Board Walnut Review + Timeless & FIDE DGT Pieces

Is there a rosewood version of the board?
Sure.
I do have a Rosewood DGT USB board. It's not the bluetooth, it's the USB-C version, but the Rosewood bluetooth version exists as well: https://digitalgametechnology.com/products/home-use-e-boards/bluetooth-e-board-rosewood

Well, it'd take a millisecond to wonder and check if the DGT site has a section from where to download the drivers..
Here it is anyway
