This is an Arduino servo driver shield. It has a PS2 interface for using a PS2 handle control. It contains 10 IO interfaces used to connect servos or other sensors. in addition, we have also extended RX/TX interfaces to interface with serial communication modules like BT modules. There are two LM2596 voltage regulator ICs onboard, which can provide a stable 600mA current for each servo.It is also applied to mechanical structures such as robotic arms.
