Electronics

The electronic components of your Witbox printer have been carefully selected to 
ensure it is capable of printing independently, without the need to be connected to a 

computer. Essentially, they comprise:

•   RAMPS 1.4 board with mosfet heat sink: the RAMPS 1.4 is a fully independent 

board designed by the RepRap community. You can find all the diagrams and 

blueprints related to the board at the link below:

www.reprap.org/wiki/RAMPS_1.4

•   Freaudino Mega 2560 v2.0

 (design derived from the Arduino Mega 2560).

•   4 x A4988 StepStick drivers featuring four layers for improved heat dissipation 

and to help prevent overheating.

•   LCD  screen and SDHC card reader.
