Sn4ke:
Hi all,I also bought these modules.
I want to use them with a 5V Arduino.
As I have V1.5, I can choose between 3,3V and 5V.But I don't see any 3,3V regulator on the board. As a result, how can the board supply the SD card with 3,3V (remember that SD cards only works with 2,5V-3,6V !) ?
Can anyone confirm that if I change the strap position from 3,3V to 5V and supply it with 5V, my 3,3V SD Card won't burn ?
Other questions, do someone have tried 2GB cards (not 4Gb or more SDHC card) with a 1GB partition ?
Thanks
the IC datasheet says "If MCU is 5V powered , you have to connect 470? resistors between MCU and WTV chips cables , because it is 3.3V power the WTV chip."
so i presume there are resistors on the 1.5 version of this module because mine did not burn and works fine as you can see on my previous videos. But you must change the soldered pin to 5v.
The problem is that the sound quality is low, there is background noise, it doesn't support the much more versatile UART serial communication RS-232 of arduino.
