 OpenPDU is an OpenHardware and OpenSource project for a network-connected PDU.
 
 We want to build the best firmware possible for a smart PDU, giving you the possibility to customize your own. You can build a custom PDU or retrofit an existing one. You can control as many outlet as you want, and manage a shared UPS.
