+# The OpenPDU project
+
+This repo contains the source code for the main binary of the OpenPDU project.
+
+OpenPDU is an OpenHardware and OpenSource project for a network-connected PDU.
+The goal is to build a modular system than can be used to retrofit an existing 19" rack PDU to a real networked PDU. A secondary goal is the use of commonly available hardware, where possible, at least for the main controller.
+
+## Hardware
+The first iteration will cover the scenario of a retrofit of an existing (rack) power strip. In any case we'll keep separated the system into the following modules:
+
+ - DC power supply
+ - controller board
+ - power board
+
+ The power supply will power the controller and the power board, taking the power from the existing power switch (it's uncommon to have a rack power strip without a power button; in this case it's required to add a power button).
+
+ The controller board will be a commonly available one (let's say a Raspberry PI 2/3, Orange Pi, ...). The requirements are:
+
+  - capable of running linux
+  - at least 256mb of RAM
+  - ethernet port
+  - GPIO/i2c port
+  - (40pin connector? some orangepis have only 26)
