Recently we highlighted the TP-Link TL-WR703N in a post. Some makers have used a WiFi shield to allow an Arduino to communicate with this router, and others have used the router’s PCB as a shield bridging Ethernet to Wifi. Martin wanted to interface an Arduino with the router directly, so that it could be used to send sensor data. His post describes the PCB connection points for the RX, TX and ground pins needed for serial comms with the Arduino.
