Without further delay let me introduce you to the 3D Printer Controller Module, a smart adapter module that will take your 3D printing experience to the next level.
A particular product caught my eye - this tiny but powerful device is designed to fit your RAMPS 1.4 smart controller LCD 2004 & LCD 12864, allowing you to print your 3D designs without a PC.

The standout feature of this controller module is its ability to connect seamlessly to your RAMPS1.4 shield making it an essential add-on for any 3D printer enthusiast. Its innovative design ensures smooth and precise printing, giving you the confidence to create complex structures with ease. Measuring just 6.2 x 1.9 x 2cm, this module is compact and easy to install, saving you time and effort.

It's worth noting that while this device is compatible with both LCD 2004 & LCD 12864 displays it is not designed for Reprap Discount Display.

However, these minor drawbacks are outweighed by its impressive performance and ease of use.

In conclusion it is abundantly clear that the 3D Printer Controller Module is a must-have for any serious 3D printing enthusiast.
