DMX RS485 to TTL Isolated Adapter with 3 pin XLR
This pcb can be assembled as either a DMX transmitter or receiver interface (the BOM is set up to build a receiver pcb).
The difference is the XLR connector gender and two 0 ohm jumpers for configuration.
DMX signals are transmitted or received using a 3 pin XLR connector and they are isolated using an ADM2483.
The TTL side of the digital isolator can be configured for 3.3v or 5v logic.
The logic transmit/receive signals are available on a 0.1 inch header to connect to a project that can generate or receive DMX data.
The XLR connectors used in the prototype are from Ali Express with part numbers C1019 and C1020 but it can be awkward to search for it on there. Using a search engine and searching for "C1019 C1020 XLR 3 pin" may show some Ali Express results that work better than searching directly on the site.
