Description
For an easier use of the WT588-D module with Arduino, it was decided to create a special Shield, this allows to test the module connected to Arduino or stand-alone mode as there are also K1 to K4 keys. There is also a connector for direct connection of a loudspeaker and a connector for connecting an external amplifier.
For programming the internal memory of the WT588 module, there is a connector for the SPI interface. there is also the possibility of using the module in stand-alone mode as there is a connector for external power supply. Two LEDs indicate the presence of the power supply and the busy function of the module.
