Questions & Answers

Should vcc be 5 vdc or 3 vdc, according to the spec? What is the default factory i2c address? 3 volts DC to power this device?

It requires 5 volts to function. The default address for Arduino is 27, but it is 4E for write and 4F for read for other applications.

How does this spi connect to the rest of the system? I can only see a 2 in the photos. sda and scl wire (i2c) interface?

I2C. omly

I'm attempting to make this work with a teeny 4, but it's proving difficult. It is completely unknown to the teensy. I haven't tried it yet with a nano. any cues?

(Amazon emailed me with this question)br>br>I'm assuming you've double-checked your wiring. Because the contrast was too high when I first tried it, I couldn't see anything. It can be adjusted with a pot on the back. br>br>The I2C address is the only other thing to consider. It's usually 27, I believe. Mine was.

Is it possible to set the I2C address to 4E?

As far as I'm aware, there aren't any. Three solder bridges on the board can be used to change the address, but not to 4E.

Work as it should

4/5

Work as it should. br>Dimensional data would be useful, as dimensional differences exist between suppliers. On any of them, I was unable to locate any information. Reverse engineering is a fun way to get the right measurements.
