Specification

Description

ESP8266 ESP-12E Development Controllers are easy to program by using the CP2102-USB interface without having to press the flash and reset buttons before each flash operation. The development board has GPIO, PWM, IIC, 1-wire, and ADC integration all in one board. Compatible with smart link smart grid. The fast and affordable technology for WiFi. Make your development the fastest way combined with firmware for NodeMcu.

The ESP8266EX integrates a Tensilica L106 32-bit RISC processor which achieves extra-low power consumption and reaches a maximum clock speed of 160 MHz. The Real-Time Operating System (RTOS) and Wi-Fi stack allow 80% of the processing power to be available for user application programming and development.

Memory

  • 32 KB instruction RAM
  • 80 KB user data RAM
  • 16 KB ETS system data RAM
  • External QSPI flash: up to 16 MB is supported (512 KB to 4 MB typically included)
  • IEEE 802.11 b/g/n Wi-Fi
  • Integrated TR switch, balun, LNA, power amplifier and matching network
  • WEP or WPA/WPA2 authentication, or open networks
  • 16 GPIO pins
  • SPI
  • I²C (software implementation)
  • I²S interfaces with DMA (sharing pins with GPIO)
  • UART on dedicated pins, plus a transmit-only UART can be enabled on GPIO2
  • 10-bit ADC (successive approximation ADC)



All ESP8266 variants have a ESP8266EX core processor and a Tensilica L106 32-bit micro controller unit. This is a low cost, high performance, low power consumption, easy to program, wireless SoC(System-On-Chip). It provides capabilities for 2.4 GHz Wi-Fi (802.11 b/g/n, supporting WPA/WPA2), general-purpose input/output (13 GPIO), Inter-Integrated Circuit (I²C), analog-to-digital conversion (10-bit ADC), Serial Peripheral Interface (SPI), I²S interfaces with DMA (sharing pins with GPIO), UART (on dedicated pins, plus a transmit-only UART can be enabled on GPIO2), and pulse-width modulation (PWM).

It has a build-in programmer and a voltage regulator, that allow flashing and powering the device via micro-USB. The system operates at 3.3V.

32-bit Tensilica Processor

The ESP8266EX microcontroller integrates a Tensilica L106 32-bit RISC processor, which achieves extra-low power consumption and reaches a maximum clock speed of 160 MHz. The Real-Time Operating System (RTOS) and Wi-Fi stack allow about 80% of the processing power to be available for user application programming and development.

Power-Saving Architecture

The ESP8266EX microcontroller integrates a Tensilica L106 Engineered for mobile devices, wearable electronics and IoT applications, ESP8266EX achieves low power consumption with a combination of several proprietary technologies. The power-saving architecture features three modes of operation: active mode, sleep mode and deep sleep mode. This allows battery-powered designs to run longer.

Small Size

ESP8266EX is integrated with a 32-bit Tensilica processor, standard digital peripheral interfaces, antenna switches, RF balun, power amplifier, low noise receive amplifier, filters and power management modules. All of them are included in one small package, our ESP8266EX.


High Durability

ESP8266EX is capable of functioning consistently in industrial environments, due to its wide operating temperature range. With highly-integrated on-chip features and minimal external discrete component count, the chip offers reliability, compactness and robustness.


Arduino Core

There are a variety of development environments that can be equipped to program the ESP8266. You can go with a simple Notepad/gcc setup, or fine-tune an Eclipse environment, use a virtual machine provided by Espressif, or come up with something of your own.

Fortunately, the amazing ESP8266 community recently took the IDE selection a step further by creating an Arduino core. If you’re just getting started programming the ESP8266, this is the environment we recommend beginning with, and the one we’ll document in our projects. This ESP8266 core for Arduino is based on the amazing work by Ivan Grokhotkov and the rest of the ESP8266 community. Check out the ESP8266 Arduino GitHub repository for more information. We provide a step-by-step instruction covering the setup of the Arduino core for the ESP8266 here.

Easy to use for WLED

Easy to install wled on these to program led lights. 2 of the 3 boards worked. The other didn't power on or be recognized by my computer.
