This projects uses 2 independents power sources. One 5V for nVidia Jetson and another 7.2V to power up Tamiya TBLE.
The TBLE is connected to Jetson via i2c PWM Servo Motor Drive and Servo Multiplexer.
So in the end there are 2 independent circuits connected and measuring levels from the other. Is not neccesary join GNDs from 2 batteries to have a common ground ?
Aditionally the 3 pin of TBLE (PWM signal) provides 5V to power up the RC receptor/Servo in normal use. So, is not strange join this references with de 5 volts in Adafruit PWM Servo Drive?
I'm not electric expert, sorry if this are a dumb question.
