+// but also acting as a sort of protection)
+
+// We have many free pins on the ESP32-S3-WROOM-X-Y module, perhaps it is best to use one of its pins to control TXEN, and use
+// DIO2 as an extra interrupt, but right now Meshtastic does not benefit from having another interrupt pin available.
+
+// Adding two 0-ohm links on your PCB design so that you can choose between the two modes for controlling the E22's TXEN would
