Typically, servos are controlled by using a PWM signal. cf:
https://stackoverflow.com/questions/50203064/pwm-on-beaglebone-black-v4-14
However, the documentation for this servo
https://www.robotshop.com/media/files/pdf2/_eng_herkulex_manual_20140218.pdf
indicates that this servo uses 115200bps 8n1 TTL level SERIAL communication
-- eg: a UART.
Unfortunately, the diagram on page 51 indicates that "TTL" means
original 5V TTL. 5V will kill a Beagle -- the pins are limited to 3.3V. The
diode/resistor set shown at the top left /might/ imply that the TTL is
using a pull-up circuit -- in which case feeding 3.3V instead of 5V may be
sufficient.
