Spkr Xpansion Module

I did research on what parts to use for the amplifier and speaker add-on, i thought of using the MAX98357A ic but it wasn't widely available in india and is kinda expensive, so i thought on using the NS4168 Ic, cheap and available (costs approx 1.5$) and is widely available here. Im doing more research about that ic from the datasheets and have added it and the hackxspansion connector symbol to the schematics, and i had to make my own symbol for the NS4168. Most time went on selecting which amplifier ic to use as there are many generic ones availabel, and selecting the best website to buy them off. And took approx 15-20 mins to make the symbol from available pinouts. (its in esop-8 package btw)
