Audio FX Board Substitution

by BluesPwr1009 on Mon Aug 19, 2019 10:20 pm

I am working to build the Ray Gun Blaster project and I am trying to gather all the parts. I see the part# 2133 Audio FX Board is out of stock. Other than physical size, is there any reason I can't substitute the part# 2342 Mini Audio Fx Board for this project? Are the boards essential identical except for the 3.5mm jack?

From what I can tell, the difference between 2133 and 2342 is the 2133 has "volume" controls, meaning it has some form of amp built in.

It appears the 2342 is literally a "line-out" only device. It is expecting you to control volume via an external amplifier.
