Question RVL-AMP & Potentiometer Question

[Omar Elsayed]

Is it possible to connect a potentiometer to the RVL-AMP, or the U-AMP for volume control?
Also, does anyone know if the Forever Pak 64 has an SD card slot so I could make backups of saves?

The RVL-AMP and U-AMP both support using linear potentiometers to control volume. There's an explanation and a wiring diagram on the 4layertech pages for the products on how to do it

What about circular potentiometers? I want to use the same one used in the GBA.

Linear refers to the resistance taper. There are linear taper potentiometers and audio/logarithmic taper potentiometers.

You can use any B103 10k ohm linear wheel pots with 3 legs to mimic the GBA's wheel, like the Ashida does

Alright, so I bought that same potentiometer from Amazon, but the seller messed up and gave me the one with 5 legs. Do you know any way I can connect it to the RVL-Amp?

Yeah just cut off the 2 extra legs and it'll work the same, with the same pinout. The 5 pin versions of the potentiometers just have an extra channel that we don't need in this case

Which pins? Are they the second on from the middle from both sides?
