1.Specification
Specification
- Module power 3.3V, regular current consumption at 70ma, peak current at 240mA (300mA must be able to provided)
- +20Dbm power, 100M max transmitting distance on ideal circumstance.
- It is common and correct to see some random error data when module is power up, and end up with "ready" (Turn baud rate to 115200 can see this actual debug data, this is used for firmware updating)

- Ultra-small size module 11.5mm * 11.5mm
- Built-in 10 bit precision ADC
- Built-in TCP / IP protocol stack
- Built-in TR switch, balun, LNA, power amplifier and matching network
- Built-in PLL, voltage regulator and power management components
- 802.11b mode + 19.5dBm output power
- Supports antenna diversity
- Off leakage current is less than 10uA
- Built-in low-power 32-bit CPU: can double as an application processor
- SDIO 2.0, SPI, UART
- STBC, 1x1 MIMO, 2x1 MIMO
- The guard interval A-MPDU, the polymerization of the A-MSDU and 0.4 s of
- Within 2ms of the wake, connect and transfer data packets
- Standby power consumption is less than 1.0mW (DTIM3)

2. Connection
3. Connect
ESP8266 to Arduino
TX to PIN1
RX to PIN0
CH_PD to 3.3 Vcc
Vcc to 3.3 vcc
GND to GND
VDO
4. Test Arduino Board
load simple blinking led pin 13 make sure board connected
code
void setup() {
// initialize digital pin 13 as an output.
pinMode(13, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(13, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(13, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
5. serial monitor check AT Command

5.1 AT
Should get OK
5.2 AT+GMR
version
5.3 AT+CWMODE?
Mode will show 1,2 or 3
5.4 AT+CWLAP
Will show Access point around
5.5 AT+CWJAP="User","Password"
connect Access point
5.6 AT+CIFSR
Get IP
All OK mean connected.
