ESP8266-ESP14 WiFi Serial Transceiver Module

The ESP-14 is kind of like a multi-core ESP8266, combining an ESP8266 mcu with a STM8S003F3 microcontroller.

The purpose of this combination is to provide more I/O pins than a regular ESP8266 based board such as ESP-12x, acting as an I/O extender.

The STM8S003F3 mcu is 20-pin packaged low-cost 8bit mcu running at 16MHz, with 8kb flash memory and 1kb RAM. It sports 16 GPIOs, of which 5 multiplexed 10-bit ADC channels, and UART Tx (PD5) and Rx (PD6). Well, unfortunately, the UART ports are also two of the ADC ports,so this will restrict to 3 available ADCs, 2UART and 11 digital IOs (configurable as I2C or SPI bus too). The ESP-14 board’s 22 pins breaks out all of STM8’s pins, plus the ESP8266 VCC and GPIO0 pins, to control flashing of the ESP.

Features of ESP-14

• Based on ESP-12E prototype design

• Inside adds STM8S003F3P6, STM8S can control ESP8266 by AT commands. The module is a complete STM8S MCU, can operate WIFI via STM8 microcontroller programming..

• Very compact package size and ultra-low power technology

• Can be widely used in smart home network and IoT, for connecting the device to the user’s physical Wi-Fi wireless network for Internet or LAN communications, networked functions.

• The module is built into a powerful STM8003 chips, all the pins are lead out, and the serial port from STM8003 is connected with ESP8266
