Is there a way to hook up one of the whispernode lora hardware buttons to reset the MCU? From the schematic it looks like the MCU RESET pin is directly tied high but want to make sure I'm not missing some other way to do this.

Hello rdpn. You're correct, the MCU RESET is pulled high and also connected to the Serial DTR line via a capacitor, so a "pulse" is produced when programming via UART.

If necessary you can add a switch between the RST pin (next to D13) and the ground. So if you press the switch, it'll reset the MCU.
