## Questions & Answers

**Q: Is there antes sample code and usage of compatible audio libraries? I’m most interested in capturing voice and streaming over http to do voice rec**
A: There are a few. Marcel something on YouTube has a few videos explaining this particular module. The different audio codecs confused me a little at first. This module uses the Es8388 instead of AC101. There need to be more videos explaining the difference between the two codecs. Maybe an idea for a video particularly on the es8388 codec and setup. I tried using the Expressif Tools but my Chinese isn’t the greatest. These boards make great audio workstations with a little Programing experience anyone can get these up and running.

### ⭐⭐⭐⭐ Excellent board - had up and running in 5 min - Library matters!
*by A***N on May 23, 2024*

I do agree the mfg, seller etc should steer people to the right libraries to get this off of the ground easier. I found the library before I found the board so in my case the longest part was waiting 2 days for the board to arrive. Go to Git Hub and find Arduino-Audio-Tools and look under Audio Kit and you're good to go in Arduino IDE - piece of cake. I got the board for the same reason as the library author. It makes trying new things painless without constantly having to rewire breadboards. There's a bunch of buttons, dip switches (pay attention to them when using the library code it's usually commented at the top of the code as to required dip switch settings). Things I'd change (and will be on mine) is that the JST headers point vertical when the usb, sd and audio jacks are horizontal. The other thing is the BLINDING green led. I may remove or see about a stronger smd resistor.
