4
+
5
+The ESP8089 module supports standard IEEE802.11 b/g/n protocols and a complete TCP/IP protocol stack. Hardware-wise, developers only need to communicate with an external MCU via the SPI/SDIO interface or the CPU AHB bridge interface.
6
+
7
+The module supports energy-saving VoLP for fast switching between sleep/wake modes, adaptive wireless bias for low-power operation, front-end signal processing, fault isolation, and wireless coexistence features to eliminate interference from cellular/Bluetooth/802.11. It is widely used in home automation, security, smart appliances, wearables and remote controls, drones, OTT boxes, and industrial IoT.

+## PCB Layout Guidelines
74
+
75
+![](2025-07-16-13-50-19.png)
76
+
77
+1. Pin 11 (WiFi_ANT) output impedance is 50Ω. No matching required for the module, but it is recommended to reserve a π-type matching network for antenna tuning.
78
+2. Pin 9 (EN) is active high. Refer to the recommended circuit, or control via MCU I/O.
79
+3. Keep SDIO traces as short as possible.
80
+4. Avoid routing traces under the Wi-Fi module on the main board, and keep away from sensitive components (crystals, cameras, etc.).
81
+5. After soldering the module, perform antenna matching and RF performance testing.
