I have noticed a too High Voltage at 3-wire PWM comming from ESC (Tamiya TBLE04-S).
In the normal use a Battery of 7.2V is connected to the ESC. To power up the rest of circuits (Servo, RC receiver) the 3-wire of the ESC provide energy at 5V (at least in theory), stepping down from the battery.
I'm my particular setup I'm using an ATX PSU to power up the system while testing. A line of 5V from the PSU powers the Jetson and the I2C_16-Channel_PWM. DC-DC converts 12V-->7V to power the ESC.
With the ESC switched off, all voltages are in range, but when I switch on the ESC, a 5.9V comes from 3-wire ESC.
This high voltage is propagated to the I2C_16-Channel_PWM to the Jetson. Measuring GPIO pins on Jetson now are 5.9.
Is not this to HIGH?? Could not damage the Jetson??
Maybe a Voltage limiter should be used in 3-wire output.
