Requires soldering. This is actually an extension that belongs to a third party machine, but can be used with some “hacking” with any GRBL-based controller, by attaching the RX line of the screen with the internal TX line of the controller, the TX line of the screen with the internal RX line of the controller, and the screen’s 5V and the GND of the controller. Our GRLB CNC controller (x controller clone) has breakout contact to make this easy. Other controllers (i.e. original x controller or other GRBL based controllers) may require to locate the RX, TX, 5V and GND contacts to solder or attach the lines to.
