It looks like someone had a similar issue here, although not identical since he was communicating with a xenon. Could it be an issue where a Boron is powered via 5v, whether USB or on the VUSB pin, it shorts the RX pin? > [@Serial problem on Boron](https://community.particle.io/t/serial-problem-on-boron/49164): > > I observe a problem with a Boron which I don’t understand and I wanted to check whether someone else had the same/a similar issue. My intention is to interface a Boron directly with a Xenon via their Serial1 ports. You may ask why, because they could communicate via the cloud or via mesh, but hear me out, please. In my use case, the Xenon is part of a mesh network for home automation/security. The mesh itself is connected via a Xenon gateway (using ethernet) to my ADSL ISP and hosts a user inte… --- _[View the full topic](https://community.particle.io/t/level-shifter-for-uart-data-on-boron-lte/62105)._
