Hi Guys
I’ve got one of these so called MP3 Recorder boards from Jaycar, but the chip also happens to be a decoder.
In fact, I don’t think it can encode to MP3 at all!
http://www.jaycar.com.au/arduino-compatible-mp3-recording-module/p/XC4516The board overall wants a 5V supply, although the VS1003 decoder chip wants a 2.7 V supply for it’s core,
and can take up to 3.6V supply for it’s IO logic. The 2.7 Volt supply regulation is on the board itself,
as I suppose is also a 3.x V supply for it’s logic.
What I’m wondering is why this would be sold with Arduino shields and the like,
when it’s IO is connected straight to the pins on the chip, and should be 3.6 Volts max.
What sort of Arduino board would supply the 5V power, and talk through the IO at 3.6 Volts?
Also if you’re up for a laugh check out the data sheet of the module on Jaycar's site (not the VS1003 chip itself).
Cheers
