Duet 3 Uart voltage tolerance
-
Hi, I have the Duet 3 6HC board, and I'm wondering about Uart communication between the Duet board and any other peripheral and the voltage that Uart is tolerant to. Specifically, I'm trying to get the duet board to communicate with the Nordson Ultimus V, and I'm not sure if the Uart handles only 3.3V, or handles 5V. Thanks

@BryanPlummer I presume you are looking to connect to the UART through one of the IO connectors. All IO_IN ports will tolerate up to 30V, so 5V from a device is no problem. However the signal level on the IO_OUT port is 3.3V and that may not be enough for a 5V device.
