Description
The Designer Systems DS-
SCX18.S is an eighteen [18] chan-
nel RC servo driver with advanced
servo control features.
Specifically targeted at the Ar-
duino UNO board user [all other
Arduino boards supported] and the
Raspberry-PI the SCX18.S fea-
tures high speed I
2
C communica-
tion for easy project integration
and smooth speed control.
Once connected each servo can be
positioned (with speed control),
enabled, reversed and soft-started
by simply writing a value to an
internal register over the connect-
ed I
2
C interface.
The SCX18.S caters for the major-
ity of servos by providing a wide
pulse width range of 0.50mS to
2.50mS with 8uS per step accura-
cy and also provides global activa-
tion of new servo position, soft-
start & movement complete regis-
ters for superior control.
The SCX18.S provides dual high
power regulators capable of sup-
plying 5V @ 3A to the connected
servos from an external Li-Pol or
Ni-MH battery pack of 7.2 to 8.4V
and features a disable link to allow
the use of low voltage battery
packs of 3.6 to 4.8V.
The on-board I
2
C pull-ups are
jumper configurable to allow dis-
connection when connecting to the
Raspberry-PI, which has its own
pull-ups.
Applications
The SCX18.S has applications
in robotics, including quadru-
ped, hexapod and octopod ro-
bots, process control & sensor
manipulation when used in con-
junction with standard RC ser-
vos.
