If you want to go wireless and stick with the mini Rambo you could then get a raspberry pi and have the wireless control all set through it. It’s what I use with CNCjs and it is nice to not have to connect with wires.
It will be interesting to see what develops with the ESP32 controller boards. https://www.cnx-software.com/2019/06/26/open-source-esp32-3d-printer-board-marlin-2-0-firmware
