I would like to control a mini Maestro using SBUS commands from my FRSky receiver without having to insert an Arduino between the two as a “message content translator”. My thought is to convert the SBUS signal to TTL serial using an SBUS2UART converter (e.g., https://www.aliexpress.us/item/3256807884428722.html). Obviously I would have no control over the message content, so will the mini Maestro be able to understand the message? Is there a way to modify the message expected by the mini Maestro?
Thanks!
Hello.
For the Maestro to acknowledge or respond to the UART signal you are sending, you must send specific bytes in a specific order. You can find details about the supported commands in the “Command Protocols” section of the Maestro user’s guide. The command protocols cannot be modified. Programming a small microcontroller board to process your UART signal and convert it into the appropriate bytes like you described seems like a good option.
