【Note】:
ESP8266 Module is not capable of 5-3V logic shifting & will require an external Logic Level Converter. Plz do not power it directly from your 5V dev board.
【Boot Option】
GPIO0: Flash Mode, High, Run the program that is already uploaded to the module
GPIO-0: UART Mode Low, Programming mode for Arduino or any serial communication
GPIO2: Flash Mode, High, Run the program that is already uploaded to the module
GPIO2: UART Mode High, Programming mode for Arduino or any serial communication
【Pin Connection】:
1.GND: Ground. Connect to ground on MCU
2.GPIO2: General Purpose Digital I/O
3.GPIO0: General Purpose Digital I/O
4.Rx: Receive Data. Connects to Rx on MCU
5.Tx: Transmit Data. Connects to Tx on MCU
6.CH_PD, CH_EN: Enable / Power Down. Active High, must be pulled to 3.3V directly or via pull-up resistor to enable
7.RST: Reset. Active low, must be pulled to 3.3V directly or via pull-up resistor 8.VCC: Connect to +3.3V only
【ADVANTAGES】
| The ESP8266 ESP-01 WiFi Wireless Transceiver Module is a self-contained SoC (system on chip) with integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network.
| The ESP8266 supports APSD for VoIP applications and Bluetooth co-existing interfaces, it contains a self-calibrated RF allowing it to work under all operating conditions and requires no external RF parts.
| The ESP8266 has a built-in UART (universal asynchronous receiver/transmitter) which can be used for TTL serial communication and/or flashing the chip. To be able to use the UART, a 3.3V USB to TTL serial converter is required. The USB to TTL serial converter must be able to supply at least 300mA
| The ESP8266 Serial/UART to WiFi module is a great way to connect for Arduino or other microcontroller projects to a WiFi network
【APPLICATION】
| VoIP applications, IP camera, Baby monitor
| Sensor network, Internet controlled robot
| IoT (Internet of Things) Project solution, Cloud Connectivity
| Home automation and security, Home and industry-based wireless control
| The ESP8266 ESP-01 can be used as Station or Access Point or both combined, Can be programmed for Arduino IDE or AT-commands or Lua Script.
