Particle Boron i2c Bus dead

Purchased particle Boron and Argon in march this year, been using both in the exact same way and have both been flawless.

In the last two weeks, i noticed the i2c LCD connected to my Boron no longer shows anything on the display. I have spent 2 weeks testing, factory resetting, reflashing, trying example sketches, all to no avail. Device would receive flash OTA ok and via USB however the i2c bus seems to be unresponsive. As a last-ditch effort I have tried factory resetting the device but now it will not reconnect to the cloud dashboard. The sim shows as active but the device does not appear in my devices.

I am happy to try and get it connected to my account using CLI over serial but my main concern is that the i2c bus is in fact dead.

@Graham @Core


I haven’t run into that issue, it might be best to do a copy-paste into the Particle support forum. I’d be interested to hear what the way forward was.

Does core not support this through local (AU) warranty?
