I want to use DMX512, and found a library DmxSimple, which uses a single (non UART) GPIO pin as output (see DmxSimple.wiki.
I currently use a TTL RS485 board, which does not have any TVS/polyfused protection.
I was wondering if I can use an UART RS485 board like this and only connect the Arduino GPIO pin (e.g. 2, thus not an UART pin) to the RX of the UART RS485 board?
So basically, my question is: can I connect using DmxSimple library use GPIO pin 2 to connect to TX of the following board?
