Ai Thinker ESP-07S ESP8266 Serial WiFi Module is a compact version of the ESP-12F and ESP-12E WiFi modules, without an onboard antenna! Compared to the ESP-12 modules, it is more compact(bottom row of pads have been removed) and has a U.FL antenna connector.The module supports standard IEEE802.11 b/g/n agreement, complete TCP/IP protocol stack. Users can use the add modules to an existing device networking or building a separate network controller.SpecificationsModule ModelESP-07sWIFI802.11 b/g/nFlash4 MBOperating Temperature (°C)-40 to 125SecurityWPA/WPA2Frequency Range2.4GHz-2.5GHz (2400M-2483.5M)Operating Voltage3.0~3.6VOperating Current80mAExternal InterfaceN/ALength (mm)16Width (mm)17Height (mm)3Weight (gm)3Shipment Weight0.005 kgFeatures:802.11 b/g/nIntegrated low power 32-bit MCUIntegrated 10-bit ADCIntegrated TCP/IP protocol stackIntegrated TR switch, balun, LNA, power amplifier and matching network Integrated PLL, regulators, and power management units Supports antenna diversity Wi-Fi 2.4 GHz, support WPA/WPA2 Support STA/AP/STA AP operation modes Support Smart Link Function for both Android and iOS devices SDIO 2.0, (H) SPI, UART, I2C, I2S, IRDA, PWM, GPIOOperating Current 80 mAOperating Voltage 3.0-3.6 V STBC, 1×1 MIMO, 2×1 MIMO A-MPDU & A-MSDU aggregation and 0.4s guard interval Deep sleep power <10uA, Power-down leakage current < 5uA Wake up and transmit packets in < 2msStandby power consumption of < 1.0mW (DTIM3) 20dBm output power in 802.11b mode Operating temperature range -40C ~ 85CPackage includes:1 x Ai Thinker ESP-07S ESP8266 Serial WiFi Module
