Product Description
ESP8266 Serial to Wifi Module ESP 12S ESP-12S For IoT Devices
The ESP-12S WiFi module was developed by Ai-Thinkerss Technology. The core processor
ESP8266 integrates the industry-leading Tensilica L106 ultra-low-power 32-bit micro MCU in
a small package with 16-bit Lite mode, clocked at Supports 80 MHz and 160 MHz, supports
RTOS, and integrates Wi-Fi MAC/BB/RF/PA/LNA.
The ESP-12S WiFi module supports the standard IEEE802.11 b/g/n protocol, a complete
TCP/IP protocol stack. Users can use this module to add networking capabilities to existing
devices or to build separate network controllers. Used for home automation, industrial
wireless control, baby monitors, wearable electronic products, wireless location sensing
devices, wireless positioning system signals, other networking applications.
The ESP8266 is a high-performance wireless SOC that offers maximum utility at the lowest
cost and unlimited possibilities for embedding WiFi functionality into other systems.
Features:
- The smallest 802.11b/g/n Wi-Fi SOC module
- Low power 32-bit CPU, can also serve as the
application processor
- Up to 160MHz clock speed
- Built-in 10 bit high precision ADC
- Supports UART/HSPI/IIC/PWM/ADC
- SMD-16 package for easy welding
- Integrated Wi-Fi MAC/BB/RF/PA/LNA
- Deep sleep current as low as 20uA
- Embedded lwIP protocol stack
- Supports STA/AP/STA + AP operation mode
- Support Smart Config/AirKiss technology
- UART baudrate up to 4Mbps
- General AT commands can be used quickly
- Supports remote firmware upgrade (FOTA)
