    Great WIFI module. Be aware that the baudrate is 115K2, and that the CH_PD pin should be connected to 3v3. Furthermore, many of the code examples from internet don't work, because they apparently are for the older version of this module (57K and slightly different command response). To get thing quick up and running I connected the module to a USB TTL module, and typed the commands in a Serial port terminal. For more info see : http://www.electrodragon.com/w/Wi07c and don't use the example code.

    3 links for information about this microcontroler : - forum : http://www.esp8266.com/ - Wiki : https://github.com/esp8266/esp8266-wiki - using with arduino : http://zeflo.com/2014/esp8266-weather-display/

    For this price, you will get an awesome WiFi chip that can be used with arduino OR can be used standalone. For arduino use, the baudrate is 9600 or 115200 (mine was 9600 by default). Note: if you use putty for testing, you will need to press (CTRL+J) after you press the ENTER key, in order to write AT commands (because putty only sends CR and the ESP-01 needs CR+LF) Bootloader is at 75000 baud (76800 will work as well). Great community around to develop for the ESP8266 as standalone chip (complete SDK available). To power up, please make sure the following pins are set: VCC: this should be connected to a 3.3V power source (MAX 3.6V!! ) CH_PD: This should be tied to VCC as well to power the chip RST: Must be tied to VCC for operate, to GND for reset GND: Ground line To enter bootloader mode, tie GPIO0 to GND and then reset the chip. Now new firmware can be loaded into the ESP8266 Happy hacking! Mathijs

    The images on this page are vague at best follow the instructions below. CH_PD MUST be set to Vcc. at all times (or the board enters power saving) for normal mode. GPIO_0 MUST be set to Gnd ONLY when the firmware is to be updated (Write protect/Flash mode). Rx >Tx Tx>Rx Vcc>3v (use LDO) Gnd>Gnd BANGGOOD please reflect this on your PRODUCT PAGE. Latest AT Firmware AI-v0.9.5.0 AT (Firmware available on Github) Latest SoC Firmware nodemcu_20150123 (again available on Github) I have now successfully Flashed the firmware to both these versions and they work smoothly. The product is more versatile than I expected, I have created a webserver on the ESP8266 Without any other MCU, STAND ALONE WEBSERVER with battery power enclosed in the size of a matchbox.

    For now I've tested only with USB/serial converter and teraterm and Bray's terminal. Everything works properly. Pin CH_PD should be connected to Vcc and GPIO0 to Vcc during normal operation and to GND for firmware change. I've tested this module as a TCP port server connected to AP with WPA2-PSK2. No problems occured.

    This is the ideal solution to WLAN-enable a lot of do-it-youself electronics. One can even get alternative firmware on the internet for it. So you can run your own scripts on the WLAN chip - it is amazing! Together with a 5V power adapter and a 3.3 volt regulator, I bought from Banggood as well (SKU256398 and SKU126782) I've built a WLAN enabled remote switch for very little money. For those of you, who are just starting with it, I've put a description how to build it here: http://seemstowork.blogspot.sg/2015/09/home-automation-with-esp8266-how-to.html I hope it is helpful. Have fun, Tjareson

    Bought 4 of them, received within 3 weeks. Quickly tried one of them, it worked fine. The baud-rate was 9600 in contrast to a description, so maybe one has to play with it. Average current consumption was about 60-70mA, peak currents for 1 ms reached 350mA.

    I received version firmware 0160901. Supplier has windows program to upgrade firmware. After that upgrade the module can upgrade firmware itself over the internet with the command CIUPDATE.

    I am try this small stuffz with arduino mega2560. I am a damn newby, so if I can do it, you can do! WIRE CONNECTIONS (module -> Arduino pin): ===================================== VCC -> 3.3V CH_PD -> 3.3V (use bareboard to share the 3.3V without soldering) GND -> GND UTXD -> RX2 PIN17 URXD -> TX2 PIN16 ARDUINO CODE: ===================================== void setup() { Serial2.begin(9600); Serial.begin(115200); } void loop() { while (Serial2.available() ) Serial.write(Serial2.read()); while (Serial.available() ) Serial2.write(Serial.read()); } ===================================== Upload, then open the Tools/Serial Monitor and command it with AT commands: AT+RST (reset board, answer "ready" if done) AT+CWLAP (show networks around you) AT+CWJAP="ssid","password" (connect to the network, encrypt detect if you lucky) AT+CWJAP? (Ask the connection, OK is connected)

    My module arrived with firmware 0.9.2.4, which has adjustable baudrate (9600 default), see http://www.electrodragon.com/w/Wi07c#Firmware
