Looks like my board has been shipped out. Is it possible to add 12v fans to this board? 0.02amps each. I want to add 2 -3 . One for intake, 1 for the board and 1 for the power supply.

“Bromide Ligand”

The board runs at the 24v the laser runs at. 12v is not available.

You can, get a 24v –> 12v regulator or get a separate 12v psu/ power source. Either way, the board is not involved.

Also the laser power supply isn’t that strong so adding more stuff to it can kill it. Separate power supply is recommended.

Oh! thanks.

You could connect two 12V fans in series and connect them to 24V ;) (20mA shouldn’t make any difference)

I will just use a different psu and connect it to pump/fans, laser guide and led’s :)

+Ray Kholodovsky Another question, is it possible to connect a Bluetooth/ wifi module to this for printing wirelessly ?

I wouldn’t.
