Waveshare 2PCS Power Over Ethernet HAT (H), Compatible with Raspberry Pi 5/CM 5, 5V 5A Output, Stable Performance, Supports 802.3af/at Network, Isolated Switched-mode Power Supply, PoE HAT, Board ONLY

Up to 253 servos can be connected in series at the same time (requires full power), also can obtain feedback information from each servo.
360°magnetic encoder, larger angle control range. High precision, the angle control accuracy reaches 360°/4096.
Any angles can be set as the middle of the position, which is convenient for assembly.. Acceleration start and stop function, the movement effect is softer.
Compact structure design and the product appearance is more beautiful. 6-12.6V Wide-voltage input, it can directly supply power with 2s or 3s lithium battery.
High torque, up to 30kg.cm@12V. The working mode can be set by the program: servo angle control/motor model can be rotated continuously.
