Adafruit 1.2" 4-Digit 7-Segment Display w/I2C Backpack

Post by achalid »

I Recently purchased the Adafruit 1.2" 4-Digit 7-Segment Display w/I2C Backpack. It appears that the unites are defective. I attempted all kind of ideas and methods to get the units to work but to no avail, I have reached out to tech support and was directed to the forum to post my problem, so this is my second post and no resolution to my problem yet. Please let me know when I would be able to get the resolved. Thanks.

Your wiring looks fine.

How about clear photos of the soldering on the display board? Both header and LED module.

OK. You have to connect Vio to (for the UNO) 5v. That provides the pullup voltage for the I2C lines.

Hi, New issue .

I recently purchased the items in the orderNumber 2667727-6413829435 and 2662057-9227783214 the 1x2.1mm Cable doesn’t work with the Solar Lithium charger. I also purchased 3.8 / 1.3mm or 3.5 / 1.1mm to 5.5 / 2.1mm DC Jack Adapter Cable PID: 2788 and this one doesn’t work either. I am not sure which cable connects to the Solar Panel . On your site the item looks like it connects together but the one I received doesn't. I am not sure if this was shipped in error.

Please advise.

Please make a new post for this since it's a completely different issue. It will get better attention as a new thread as well.
