Hi, I know that there is documentation, but I’m finding it a little confusing.
How would I simply daisy chain two Mini Maestro (18) boards together?
Hello.
To avoid confusion, can you clarify what you are using to send the serial signals? For example, are you trying to control them both through a USB port on your computer or are you using something like an Arduino or microcontroller board?

Hi Brandon, I’ll be sending the signals from an Arduino.
Thank you for the additional information. The first step is making sure both of your Maestro’s are configured in “UART, fixed baud rate” or “UART, detect baud rate” serial mode (I recommend using the fixed baud rate option for now), and giving each of them a unique device number. You can do this for each Maestro from the “Serial Settings” tab of the Maestro Control Center. (Please note that when using the fix baud rate mode you should set the baud rate to match what your Arduino is sending.)
As far as connections, you should connect the TX pin from your Arduino to the RX pin on both of your Mini Maestro controllers. If you need to receive any serial responses back from the Maestro controllers, you can connect the TX pin from the “second” Mini Maestro to the TXIN pin of the “first” Mini Maestro, and the TX pin from the “first” Mini Maestro to the RX pin on your Arduino. Lastly, you will also need a common ground connection between all 3 devices.
If you’re using our Maestro Servo Controller library for Arduino, you can specify the device number for each Maestro in its constructor as detailed in library documentation here.

Thank you Brandon.
