This module is the right choice for the construction of a robot with several servo motors. This means that up to 16 servo motors can be controlled via I2C lines. The power supply of the motors is thereby separated in order not to overload the outputs of the microcontroller used.
Frequency: 40-1000 Hz.
Channels: 16 channels
Protocol: I2C (62 pieces can be concatenated on an I2C bus)
Address selection via 6 solder pads
Resolution: 12 bit
Power supply: 5-10 V DC
