+# Electrical Design
+
+## Explained
+The design is using an opamp as a compined level converter and a schmitt trigger, in order to convert 
+the HAN signal into a 3.3V compatible serial format. As the input levels on the opamp is much higher 
+than our 5V supply, we are rectifying and smoothing the HAN signal to use for a supply here. (VDD)
+
+As a power source, we've used a micro USB connector, providing 5V, just as this is cheap and easy. However,
+no part of the circuit will need any other power than the 3.3V, so any combination of power source and 
+regulator that provides the 3.3V will do.
+
+The ESP8266 setup is a rather standaraized setup and will allow for programming the ESP directly on the 
+board, if needed. During programming, it might be neccessary to disconnect the incoming HAN.

 # AMS <-> MQTT Bridge
 
+* [Electrical design](./Electrical)
+
+## Background
 The purpose of this project is to collect information and build a simplified bridge for reading serial DLSM/M-bus information from electrical power meters (AMS), provided over the HAN port, and publishing to some IoT friendly target.
 
 Components will be ESP8622, Arduino code, a (very simplified) M-bus <-> 3.3V serial interface
