Hi,
I have developed some simple 8mm SMD Feeders, they're equipped with an ESP32 (the controller might change lateron, currently that seems to be the best available solution; and I'm not going to use wifi).
Now my plan is to have a fixed address for each feeder slot, the feeder bank will be controlled via FPGA and ethernet.
For interfacing the feeder bank I thought about adding a buffer ic between the FPGA and the external feeder.
The communication will be done with 3v3 uart (the cables are short ~20cm max). In a future version I plan to remove the cable and add a connector directly to the feeder, but that's subject of another revision.
Now I still have the question should I add another buffer IC on the feeder itself to isolate the microcontroller pins or would it be okay to leave it as it is?
My estimate is that those feeders might be swapped on/off around 2/3 times a day.
