Description

The high-performance chip ESP8266EX powers the ESP-12F. The chip contains a sophisticated Tensilica L106 32-bit MCU with 16-bit short mode, fundamental frequency support of 80MHz and 160MHz, and RTOS support. The ESP8266EX has a full WiFi function that can be used independently as well as as a slaver with other Hoster MCUs that can start directly from the out-of-the-box Flash. Furthermore, the built-in high-speed buffer improves system performance. When combined with another MCU design, the ESP8266EX can be used as a WiFi adapter via SPI/SDIO and/or I2C/UART interfaces.

Using a USB to Serial Converter

to manually put the ESP module into programming mode and then use any USB to serial converter to program the ESP8266, CH340, or PL2303 works! but beware the 5v will destroy the chip you need to use 3.3v

Pinout of the Module:

ESP-12E Development Board — Simba master documentation

ESP8266 Module Basic Programming circuit:

to program the ESP-12 module you will need the following:

  • EN, RST, and GPIO 0 need to be pulled high using a 10K resistor
  • GPIO 15 needs to be pulled to the ground using a 10K resistor
  • 3.3V power supply capable of about 250mA of current (A cap between VCC and GND is recommended)

With this simple configuration the ESP8266 when powered on will be in Normal operating mode, so it will run whatever sketches you have programmed to it.
