(1)GND
GND provides the ground for RTM-6000 Module.
(2)Power:
Connect V_IN_3V3 pin to DC 2.9~3.6V.The power supply must add Bead and
bypassing capacitor(22~47uF).It can reduce the Noise from power supply and increase
power stability.
(3)TX
This is the main transmitting channel and is used to output user application software.
(4) RX
This is the main receiver channel and is used to receive software commands to user
application software.
(5)AUDIO_L/R
The two pin contains the Audio of the left/right channel directly out of the Si4703.
(6)FM_ANT
This pin is FM Antenna input pin. It is suggested to use 50 ohm trace from FM-ANT pin
to FM antenna connector.
