A couple of options to consider; neither are perfect solutions but could
work ok based on your application:
1) Toggle a GPIO with software, there will be 1-2KHz of jitter and you
can't guarantee that that will be the maximum jitter you ever see.
2) If the extra PWM signal can be an exact copy
That circuit will work. Yes on connecting external ground to GNDA, that
will give you a common reference. Those resistor values will allow the ADC
to see about 1.78V when the input voltage is 5V, looks like a good place to
start. As far as resistor values (1k, 1.8k vs 10k, 18k), I'd go with the
Forgot to add that you should use the GNDA as the ground reference to your
external analog input sources.

You will need to use a voltage divider to lower the detectable voltage of
your 0-5V or 0-10V inputs to a range of 0-1.8V or less. Google voltage

explanation of voltage dividers. If you look at the schematic, an example

I believe the GPS UART port could be used. PWM subsystem 0 would need to
be configured for use similar to subsystems 1 and 2 which are used for on
board drivers.

You can also get a Robotics Cape for your BBB and it will give you all the
features of the BBBlue except for the WiFi. You'll then maintain your
Ethernet interface.
By the way, the BBBlue uses a PRU for the 4th encoder. It may be possible
to use the Robotics Cape software without a
The Robotics Cape has an IMU on it along with a bunch of other robotic
related features.

Hi Phil,
Q1) I would suggest looking at rc_pwm.c which is in the
Robotics_Cape_Installer source code. A comment in the code says that there
are 3 PWM subsystems; subsystem (ss) 1 and 2 are used by the built in motor
drivers but ss 0 can be accessed from UART1; which leads one to believe is
I'm assuming you are not taking the cost of the Beaglebones themselves into
consideration as the 2 would be them most expensive parts of this project.
Here are three ways of connecting 2 BBB together there are tradeoffs with
each approach.
1) (not expensive, not the simplest) Connect the 2

Keep in mind that the 7V is Absolute Max voltage so you should operate
below this level or risk damaging the chip.

Pin 14 is the positive input for a single cell lithium (lion/lipo) battery.
Data sheet lists max input of 7V so you could use other battery
combinations/chemistries if you like, but the internal circuitry will
protect based on a single cell lithium.
Pin 16 is for a temperature sensor used for
