I need to buy some OLEDs for an IoT class. SparkFun has one that I’ve used before, but it’s $16 apiece. <a href="https://www.amazon.com/Dorhea-Display-SSD1306-Self-Luminous-Raspberry/dp/B07WPCPM5H/ref=asc_df_B07WPCPM5H/?tag=&linkCode=df0&hvadid=386649289423&hvpos=&hvnetw=g&hvrand=4764532421586912638&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9019441&hvtargid=pla-835740912703&ref=&adgrpid=77847887414&th=1" rel="noopener nofollow ugc">This one , from Amazon is $21.99 for 6, definitely more in my league, budget-wise. Does anyone have any experience with this, or, before I place my $21.99 bet, can see why it wouldn’t work?

Several reviews on the amazon page talk about the I2c address being inconsistent with the labeling, I mentioned that in the beginning of this thread . Check through the reviews and you’ll likely find the correct address, or a more direct approach would be to use an I2c scanner to find it.

Inexpensive OLED - too good to be true?

I haven’t used these, but I’m gonna order a batch. The reviews are all good, but pay attention to the i2c address comments.
