7.1 Schematics
The schematics for the VoIP Speaker Phone are presented in Figures 7.1 and 7.2.
Some parts don't need to be populated for production units. These include:
External microphone connection.
Note: The length of VS1003's microphone lines MICP and MICN should be made as
short as possible. The demo boards have these lines much longer than recommended,
which may cause trouble.
