Product Description

                 low csot 3.3Vdc ESP8266 uart to wifi module for smart home remote control    

KM26 adopted ESP8266EX platform, the chip work at 2.4G frequency. ESP8266EX is among the most integrated Wi-Fi chips in the industry. Measuring just 5mm*5mm, ESP8266EX requires minimal external circuitry and integrates a 32-bit Tensilica MCU, which features extra low power consumption and 16-bit RISC, the main frequency support 80MHz and 160MHz. With RTOS, it integrate WiFi MAC/BB/RF/PA/LNA/on-board antenna.
KM26 support IEEE802.11 b/g/n standard. Using TCP/IP complete protocol stack, user can use the module to add WiFi network function, it will also establish independent network controller.
   ESP8266EX is a high-efficiency SOC, it offer the unprecedented practicality by low cost, which offer unlimited possibilities for WiFi technology applied to other control system.
   ESP8266EX is a complete and self-contained WiFi solutions, it can not only run independently, but also work when carried on other host MCU. If ESP8266EX is loaded application as the only application processor, it will be set up from external flash. Built-in with high speed buffer memory, it is conductive to enhance system performance and reduce RAM demand.
   In other case, ESP8266EX take charge of accessing to WiFi adapter, we can add it to any MCU design, it is easy and convenient. Just need to thorough SPI/SDIO interface or I2C/UART interface.
   Great capacity for management and memory function make it integrate sensors or other application by GPIO, which occupy the least system resource.
   With highly integrated on-chip features and minimal external discrete component count, the chip offers reliability, compactness and robustness critical in end products.

  12.  HSPI,UART, I2C,I2S,IR Remote Control, PWM, GPIO
  13.  Deep sleep current is 10 μA , turn-off current is less than 5 μA .
  14.  Wake up, connect and transfer data in 2ms.


The module support general UART and network standard. Built-in TCP/IP protocol stack, users can use the module to add network function. It also can establish independent internet controller to realize data transmission between UART and WiFi internet. Using KM26 WiFi module, traditional UART device could be connected to the WiFi network without changing any configuration, to provide complete and quick solutions for UART device. There are two methods to control external devices, the first is that external MCU control WiFi module UART. Secondly, KM26 controls external devices by its self-contained UART.
