(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.
Page 10 GND provides the ground for RTM-6000 Module. (2)Power: Connect V_IN_3V3 pin to DC 2.9~3.6V @3.3V TYP..The power supply must add Bead and bypassing capacitor (10~33uF).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.

Page 12: Layout Note
6 Layout Note: (1) The trace connected to FM_IN should be 50 ohm. (2) It is recommended to add Bead and bypass capacitor above 10~33uF to reduce power noise. (3) The system’s EMI or noise is recommended to reduce first which efficiently boost TMC performance.
