Help with Optical Encoders (generic chinese module)
Greetings, Does anyone have any experience working with these Optical Encoders? Apparently these are the only options available locally for me and I need to get it to work.
I connected it as follows;
- (+) ------> 5v
- (-) ------> Gnd
- (01)------> INT0
- (02)------> INT1
But the emitter burnt out as soon as I did that. I made astack exchange post trying to find out someone who had used these earlier, but I couldn't get any solid solutions.
The assumptions so far are;
- It's not actually TTL compatible, and is just a emitter, receiver package thus would require a current limiting resistor for the emitter and a voltage divider for each of the outputs.
- I had recieved a 3.3v version, and it burnt out because I connected it to 5v
Also, could someone help me translate the Chinese label in the back? Maybe that could lead to a datasheet. Right now I ordered two more of these and am waiting for them to be delivered.
