Figure 2: Pin Assignment (Top View)
1. BOOT_CONFIG pins (WAKEUP_IN, NET_MODE, WLAN_EN, COEX_RXD, COEX_TXD,
USB_BOOT and BT_CTS
*
) cannot be pulled up before startup.
2. PWRKEY output voltage is 0.8 V because of the diode drop in the baseband chipset.
3. USB_BOOT and COEX_RXD are connected inside the module and share the same network.
