In the blog you mentioned,
Whats wid the first sentence.You also have to connect the I2C VCC pin to your logic voltage level. If you're using a 3V microcontroller, connect it to 3V. If you're using a 5V microcontroller, connect it to 5V. This is so you can have 5V powering the amplifier but 3V to keep the levels happy for your lower voltage micro.
Whats with the micro voltage about.
If I require it to be built like a pro, what can be done to built this widout the huge arduino board but wid all the configs.
How will you explain to someone the diff b/w 2.8W and 20W.
Can it be powered and played just like the MAX9744 amp,i.e., in analog mode. no config. plug-and-play.
Are its designs, Schematic and PCB, open source?Can I get it.
