Wiring diagram for VR001

do you have a schematic diagramm for the VR001?
I want to steer the robots with other hardware and therefore i need to know how the VR001 works.



here’s the schematic for the VR001

It converts the audio signal (which is actually an UART signal at 2400baud).
This is then modulated with the 38Khz carrier signal and is then passed to the IR led.
