Product Review

This new upgraded silent mainboard does not currently come pre-installed on our Ender 3, Ender 3 Pro, or our Ender 5 printers. At this point, the silent mainboard is a separate upgrade for all 3 Ender's series 3D Printer. The firmware for the Ender 3 and Ender 3 Pro comes pre-installed, but this mainboard works excellent for the Ender 5 as well! For Ender 5, you will need to install the.HEX file yourself. Download here: (https://bit.ly/2FBSuHn).

For the Ender 3 and Ender 3 Pro, you just plug them in and start printing!

What's the difference between Ender 3 silent board and Ender 3 pro silent board?

Actually They can interexchange after flashing firmware.
If you just want to plug and play,please purchase the right one.It's recommended to take a few pictures of how the wires were connected and label them before installing.
If you like D.I.Y,Please write to our official email or find SOVOL Facebook group to get flash firmware.or you can download firmware in Creality Official website by yourself.
