The ESP8266 Series WiFi modules were designed by Ai-Thinker in 2014. Since its launch, it has been widely welcomed by customers around the world due to its high cost-effectiveness and powerful performance. Even with the launch of the ESP32 a few years ago, the demand for ESP8266 has not abated, with so far, the sales volume in 2021 exceeding 30 million units with the ESP-01S/ ESP-07/ESP-12F/ESP-12S being the most popular ESP8266 modules.
ESP8266 supports the standard IEEE802.11 b/g/n protocol with a complete TCP/IP protocol stack. Users can use this module to add networking functions to existing equipment or build an independent network controller. ESP8266s are high-performance wireless SoCs that provide maximum practicability at the lowest cost and provide unlimited possibilities for Wi-Fi functions to be embedded in other systems.
- Built-in Tensilica L106 ultra-low power consumption 32-bit micro MCU, main frequency supports 80 MHz and 160 MHz, supports RTOS.
- Built-in 10 bit high precision ADC.
- Wi-Fi @ 2.4 GHz, supports WPA/WPA2 security mode.
- Support AT local upgrade and cloud OTA upgrade
- Support Smart Config function (including Android and iOS devices)
- HSPI, UART, I2C, I2S, IR Remote Control, PWM, GPIO
- Deep sleep hold current is 20 uA, shutdown current is less than 5 uA
- Wake up, connect and transmit data packets within 2 ms
- Standby power consumption is less than 1.0 mW (DTIM3)
The processor supports 80 MHz and 160 MHz frequencies, runs FreeRTOS real-time operating system, and integrates Wi-Fi MAC/BB/RF/PA/LNA as well as on-board PCB antenna. The pre-loaded firmware support Android/iOS Smart Config, AirKiss one-key configuration network, and general AT commands.
The ESP-07S is our most compact ESP8266 module offered in an SMD-16 package (17x16x3mm) for easy soldering. It can be used in standalone mode booting from the 32 Mbit flash or as a slave connected to a host microcontroller through an up to 4 Mbps UART interface.
The ESP-12S is another tiny module that contrary to ESP-07S comes with a built-in PCB antenna. The ESP8266 module can be integrated into an MCU-based design through SPI/SDIO or UART interfaces, and like out other modules also provides expansion I/Os with up to 9 GPIO, UART, ADC, PWM, SPI, and I2C.
The ESP-12F module is a hot-selling module on the international markets thanks to its many global and country-specific certifications, including RoHS, REACH, FCC (USA), CE (Europe), SRRC(China), IC (Canada), KCC (South Korea), NCC (Taiwan, China), ANATEL (Brazil), and TELEC (Japan).
Our modules have already been used in many types of applications and sectors with, just to name a few, Smart Transportation, Sensor Application, Smart City, Wireless Monitoring, Smart Home, Smart Door Lock, and the list goes on.
