 ### Amplifier
 
+The Chip is a MAX98357 Class D Amp.
+Pin 1 is on the lower left side, seen from the letters in correct orientation.

 #### SD / MODE
 
 This pin is used for shutdown mode but is also used for setting which channel is output. It's a little confusing but essentially:

 For the breakout board, there's a 1Mohm resistor from SD to Vin which, when powering from 5V will give you the 'stereo average' output. If you want left or right channel only, or if you are powering from non-5V power, you may need to experiment with different resistors to get the desired voltage on SD
