The AndyMark Programmable Servos are adjustable metal-geared servos that are perfect for use in robot mechanisms. Description Documentation These servos can be programmed to include angular limits as well as continuous rotation mode, making them highly adaptable. Overall, these servos are designed to fuse many ease-of-use features into one package. The built in mounting tabs feature 10-32 sized holes on a 1/2 in. spacing making it easy to integrate into designs. Additionally, the hex output makes adding attachments a breeze. Default Mode This servo defaults to the standard angular mode and will respond to input pulses between 500μs – 2500μs. Programmable Features Programming the servos can be done with the Programmable Servo Programmer (am-3218) sold separately. Angular Mode Angular limits and run to position commands can be modified to allow full or clipped positional range. 1-turn Servos can be controlled up to ~300° in Angular mode 5-turn Servos can be controlled up to 1800° in Angular mode Continuous Rotation Mode Continuous rotation mode can be set from the programmer and allow the output to spin indefinitely in either direction. Analog Feedback The analog feedback versions of these servos has a fourth wire that can be read to determine the position of the internal potentiometer. This lets you know the output of the servo at all times and pairs well with our analog breakout board (am-5681). am-4954 and am-4954a High Torque 1-Turn Specifications: Default Angular Range: 280° Input Pulse Range: 500μs – 2500μs Size: 2.5 in. x 1.64 in. x 1.76 in.
