5.4 Expanding SC08A for 16 Channels
SC08A provides the flexibility to be expanded and control 16 channels of servo motor
simultaneously. In some application, more than 8 servos are required. No worries, 2 units of
SC08A can be combined for expansion mode to control 16 servos. Following steps will guide
user to setup SC08A for expansion mode.
1. Two units of SC08A are needed.
2. Setup both SC08A according to steps in section 5.1. User may share the same power
source for servo motor. However, please ensure power source is capable to supply
higher current since more servos are used.
3. Create a 4 ways cable for interlink between two SC08As. Following figure shows the
cable connection. Please ensure the polarity is correct. This cable connection is not
same with cable in previous section. Do not use this cable to connect SC08A with
microcontroller.
