Low-profile/slim PCIe card that allows you full control of your computer's power button and reset button, remotely. Designed to be flashed with esphome to allow remote control of relays, powered by the always-on 3.3V rail of your PC.

Note - the PCI->SERIAL bridge should be considered as not working. I have been unable to get reliable communications on Linux, and do not have a Windows PC to see if it works. The card still works with esphome and for controlling the IO's.
