RC Pulses Output
72 AX3500 Motor Controller User’s Manual Version 1.9b. June 1, 2007
Connector Location and Pinout
Figure 40 below shows the location of the RC Output connector and its pin assignment.
Three pins are provided for each output, matching the pinout of standard Futaba RC con-
nectors.
Connecting Servos and Slave Controllers
Special care must be used when connecting the AX3500 to servos or to slave control-
ler.The 5V power output has very limited current driver capability of approximately 100mA
for all 8 channels and can therefore be used to drive directly, as shown in Figure 41, only
the most efficient servos with very little load. In most applications, however, a separate
power supply must be provided to power the servos., as shown in Figure 42.
