Datasheet

The headphone jack is a classic 3.5mm as seen in just about every audio device. You can connect this directly to any

audio output. The terminal blocks are for if you have some direct-wiring project and you want a more permanent

connection. You'll have to solder in the terminal blocks if you want to use that technique, see the Assembly page

Speaker outputs

You got this amp to amplify, and this is where you get that amplified signal out! We use two dual 3.5mm terminal blocks

for the speakers, Left and Right

Oops, on the first rev of the PCB we made a mistake with the breakout labeling, swapping the two channels.

The top pin is LEFT and the bottom pin is RIGHT. The middle pin is still GND
