Of course, hit up your favorite search engine, but we found Andrew Cross a great resource for ESP information. A Serial Programming interface (SPI) has following pins in ESP8266 GPIO12 for Mater-Out-Slave-In (MOSI) GPIO13 for Mater-In-Slave-Out (MISO) GPIO14 for Serial Clock (SCLK) GPIO15 for Chip Select (CS) I2C pins ESP8266 provide only software I2C interface it means we can use any two pins for I2C but following pins mostly used. The serial wifi shield has the following features: 1.WiFi module is industrial-grade chips ESP8266, which is ESP-12E with metal shield, strong anti-interference ability 2. Shop Quality & Best Integrated Circuits Directly From China Integrated Circuits Suppliers. ESP8266-Based Serial WiFi Shield for Arduino is designed based on esp8266 by Espress if Systems, pin-compatible with Arduino UNO/Mega2560 DevBorad.

Look into the very-convenient 29248 adaptert hat mates your USB-TTL to it easily. (MEGA DEAL) US 0.96 14 OFF Buy ESP01 Programmer Adapter UART GPIO0 ESP-01 Adaptaterr ESP8266 CH340G USB To ESP8266 Serial Wireless Wifi Developent Board Module From Seller FAR EAST ELECTRONICS. then RELEASE the “program” button when the Arduino IDE finishes the compile, and start “programming…”Manually wiring it up can be a PAIN.After you click the “Program” button in Arduino, it will start compiling your program. Hook it up to a FTDI (or similar UART as shown in the product images), making sure it’s configured for 3.3V.To program, you have to toggle the GPIO 0 “PRGM” pin to ground after a low signal to the “RSET” pin, so both have to have their own momentary button connected to ground.There’s so many ways to bend this SoC (System on a Chip), but the basics are: 3.3V supply (current can spike 300mA+, depending on mode).32-bit Tensilica Xtensa LX106 CPU running 80MHz.8Mbit external QSPI flash memory (1MByte).Turns it into an access point, and lets you run BASIC programs from a web browser. They provide a nice tool for flashing the firmware. Official Espressif (the manufacturer of the chipset).

NodeMCU – a very popular firmware that gives pretty much full access to the microcontroller and wifi functions.

This is a very robust implementation of the Arduino feature set, so you can move Arduino code to a ESP8266! So what can you load onto it? There’s a few versions of firmware that you can load onto them, like:

Relays, Motors, Motor drivers, Pumps & ValvesĮSP8266 ESP-01, is a Wi-Fi module that allows microcontrollers access to a Wi-Fi network, we can give a microcontroller internet access like the Wi-Fi shield does to the Arduino, or we can simply program the ESP8266 to not only have access to a Wi-Fi network, but to act as a microcontroller as well.

These GPIOs control how the module starts up and as such require special handling if they are to be used at all. Most modules, other than ESP8266-01, also make GPIO15 accessible. All modules make GPIO0 and GPIO2 accessible. Connectors/Header pins/Stackable pins/Jumper wires It comes in a variety of module types and can be programmed in a variety of ways.
