1) Does anyone know where these modules exist and can be bought?
2) If they don't exist, does anyone know a good working circuit that would work? (Data sheet examples are not always the best).
3) Same as above for I2C
The datasheet example is quite straight forward, I would try that one (full- as well as half-duplex).
The chip doesn't support I2C.
I'm looking for *working* confirmation of it's reliability not hypothetical.
Have you tried this circuit? I'm looking for *working* confirmation of it's reliability not hypothetical.
That's not what I asked and you know it.
