ESP-13U Specification V1.0 1. Product Overview ESP-13U WiFi module was developed by Ai-Thinker Technology. The core processor of the module ESP8266 integrates the industry-leading Tensilica L106 ultra-low-power 32-bit micro MCU in a smaller package with 16-bit reduced mode. The main frequency supports 80 MHz and 160 MHz, supports RTOS, and integrates Wi-Fi MAC / BB / RF / PA / LNA. ESP-13U WiFi module supports the standard IEEE802.11 b/g/n protocol, a complete TCP/IP protocol stack.
ESP-13U Specification V1.0 Features Complete 802.
ESP-13U Specification V1.0 Parameters Figure 1 Main Parameter Model ESP-13U Package SMD-18 Size 28*14*3(±0.2)MM Antenna I-PEX，Customers can match their own antenna Frequency range 2400 ~ 2483.5MHz Operating Temperature -40 ℃ ~ 85 ℃ Storage Temperature Power range supply -40 ℃ ~ 125 ℃ , < 90%RH Supply voltage 3.0V ~ 3.

Unit 2400 - 2483.
ESP-13U Specification V1.0 Power consumption The following power consumption data are based on a 3.3 V power supply ,25°C ambient temperature and measured using an internal voltage regulator. All measurements are completed at the antenna interface without SAW filters. all emission data were measured in the mode of continuous emission based on a 90% duty cycle. Mode Min. Typ. Max. Unit Transfer802.11b, CCK 11Mbps, POUT=+17dBm - 170 - mA Transfer802.
ESP-13U Specification V1.0 Light-sleep used for CPU suspensive applications, like Wi-Fi switch. And while maintaining Wi-Fi connection, If there's no data transfer, could according to the 802.11 standard (e.g. U-APSD), turn off the Wi-Fi Modem circuit and pause the CPU to save electricity. For example, at DTIM3per 300 ms sleep mode andwake up 3 ms to receive AP Beacon packets, the overall average current is about 2mA.

ESP-13U Specification V1.0 6. Schematics 7. Design Guidance 1、Application Circuit Note： （1）、Module external circuit, GPIO0 must pull up. VCC,GPIO15 must pull down to GND. Copyright © 2019 Shenzhen Ai-Thinker Technology Co.
ESP-13U Specification V1.0 （2）、EN and RST pin must pull to VCC.
ESP-13U Specification V1.0 （3）、DC-DC power supply circuit is recommended to reserve the position of the dynamic response capacitor, and the output ripple can be optimized when the load change is large. （4）、Proposed addition of ESD Devices to 5V Power supply Interface. 4、GPIO (1) At the periphery of the module, some GPIO ports are led out, and a resistance of 10-100 ohms can be connected in series on the IO port for use. This suppresses overshoot and is more stable on both sides. Help for both EMI and ESD.

ESP-13U Specification V1.0 OEM/Integrators Installation Manual Important Notice to OEM integrators INTEGRATION INSTRUCTIONS FCC rules The ESP-13U is an Wi-Fi Module with frequency hopping. It operates on the 2400 ~2500 MHz band and, therefore, is within U.S. FCC part 15.247 standard. Modular installation instruction 1,ESP-13U Integrates high-speed GPIO and peripheral interface. Please pay attention to the installation direction (pin direction).
ESP-13U Specification V1.0 Information on test modes and additional testing requirements Data transfer module demo board can control the EUT work in RF test mode at specified test channel. Additional testing, Part 15 Subpart B disclaimer The module without unintentional-radiator digital circuit, so the module does not required an evaluation by FCC Part 15 Subpart B. The host should be evaluated by the FCC Subpart B.
ESP-13U Specification V1.0 determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: -- Reorient or relocate the receiving antenna. -- Increase the separation between the equipment and receiver. -- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -- Consult the dealer or an experienced radio/TV technician for help.
