AST-CAN485 WiFi Shield Hookup Guide 

Introduction

What would make the AST-CAN485 even better? WiFi! In order to further the communications 
capabilities of the CAN485, we present the AST-CAN485 Wifi Shield. The shield is based on the 
Sparkfun ESP8266 thing and allows for a CAN485 module to communicate over Wifi.
