When there is no data transmission while maintaining a WiFi connection, power off the WiFi Modem circuit according to the 802.11 standard (eg U-APSD). For example, in DTIM3, every sleep 300mS, wake up 3mS receive AP Beacon package, etc., the overall average current of about 20mA. Note : Light-Sleep for CPU can be suspended applications, such as WiFi switch. If there is no data transmission while maintaining a WiFi connection, the WiFi Modem circuit can be switched off and the CPU is powered down according to the 802.11 standard (eg U-APSD). For example, at DTIM3, every sleep 300 ms, wake up 3 ms to receive AP's Beacon packets, etc., the overall average current is about 2 mA. Note: Deep-Sleep is used for applications that do not have to keep the WiFi connection for a long time, such as a sensor that measures the temperature once every 100 seconds. Every 300 s wake up after 0.3s - 1s connected to the AP to send data, the overall average current can be much smaller than 2mA.

In order to get the best RF performance of the end product, please pay attention to the rational design of the module and the placement of the antenna on the bottom plate according to this guide. Option 1 (recommended): Place the module along the edge of the PCB board, and the antenna is placed outside the frame or along the board and the bottom is hollowed out; Ai Option 2: The module placed along the PCB board side, the antenna placed along the board and the bottom of the hollow; Option 3: Place the module along the board side of the board, the antenna placed along the Copyright © 2017 Shenzhen Ai-Thinker Technology Co., Ltd All Rights Reserved Page 11 of 23 ESP-01/07/12 Series Modules User's Manual V1.1 ink er board and the bottom are not copper. Figure 4.7 ESP-12S antenna placement instructions 4.3 Module Peripheral Routing Instructions The ESP8266 series modules integrates high-speed GPIO and peripheral interfaces, which can cause severe switching noise. If some applications require high power and EMI characteristics, it is recommended to connect 10 to 100 ohms in series on digital I/O lines. This can suppress overshoot when switching power supplies and make the signal smooth. Series resistance can also prevent electrostatic -T discharge (ESD) to some extent. 4.4 GPIO Level Conversion Ai Figure 4.8 Transistor level conversion Copyright © 2017 Shenzhen Ai-Thinker Technology Co., Ltd All Rights Reserved Page 12 of 23 ESP-01/07/12 Series Modules User's Manual V1.1 ink er 4.5 Power Supply Reference Design Figure 4.9 Power supply reference -T 4.6 ADC Supply Reference Design Ai Figure 4.10 ADC supply reference Copyright © 2017 Shenzhen Ai-Thinker Technology Co., Ltd All Rights Reserved Page 13 of 23 ESP-01/07/12 Series Modules User's Manual V1.1 ink er 4.7 Automatically Download Reference Design Figure 4.11 Automatically Download Reference Design Ai -T 4.8 Reflow oven temperature curve Figure 4.12 Reflow furnace temperature curve Copyright © 2017 Shenzhen Ai-Thinker Technology Co., Ltd All Rights Reserved Page 14 of 23 ESP-01/07/12 Series Modules User's Manual V1.1 5 Usage Guide ink er ESP8266 series module factory default built-in AT firmware, and the default baud rate of 115200, can refer to 4.1 typical application diagram to build the minimum system circuit, then the AT command operation.
