1. AP6398XU Evaluation Board Introduction
AP6398XU Evaluation board (EVB) likes as figure1. That is designed for IEEE802.11
a/b/g/n 2x2 WLAN with integrated Bluetooth and FM application. It is subject to provide a
convenient environment for customer’s verification on WiFi or Bluetooth function. There
are many controller pins and reserved GPIO on Evaluation board which describes as
below.
