  • Great for Learning and Protyping ESP8266
Color: 2pcs CP2102
I purchased this pair of boards and, overall, I am very pleased with my purchase. They arrived well packaged with the boards in individually sealed, anti-static bags. Inside each bag, the board was pressed into a foam sheet to protect the pins from damage. I have worked a lot with static sensitive electronic devices, and these were well packaged for optimum protection. Although I haven’t done extensive testing with the boards yet, I did verify that both are functional. They came with the NodeMCU “AT” firmware loaded, but I use them with the Arduino environment and load ‘sketches’ to them. There is no documentation provided with the boards, but I think that most of the buyers of these boards are pretty adept at finding documents on the internet. Using Windows 10 Home edition, the Silicon Labs CP210x USB driver loaded automatically. I think Win10 downloaded the driver from the internet because the search & loading process took about 60 seconds. Once the driver is loaded, connection time to the PC is nearly immediate upon plugging into the USB port. A little experimentation with different micro-USB cables confirmed that cable length does matter. Although the module receives power and will function on a longer cable, getting the device recognized as a COM device with a cable longer than 3-feet (1 meter) is not reliable. Some of my 6-foot cables worked, and some did not. I recommend cables of 3-ft or less for programming and debugging. I only tested the COM port speed at 115.2Kbps and 230.4Kbps; both worked fine. I did not try to load sketches faster than 115.2Kbps. I was not finding any information on which “board” to select in the Arduino environment, so I chose “NodeMCU 1.0 (ESP-12E Module)” and it seems to work perfectly. After loading programs that generate web pages to control I/O pins, both boards connected quickly with my home network. In addition to securely connecting to my home network, I also have the boards set to simultaneously act as Wi-Fi “access points”. The default access point name is “AI-THINKER_” followed by the last six characters of the device’s MAC address. If you let your PC connect to it, the module will provide your PC with an IP address (yep, these things have onboard DHCP service) and you can access your web page(s) by pointing your web browser to 192.168.4.1. I have not looked into whether the access point name or IP are changeable, but the IP settings for the module’s connection to my home network are easily changeable. One of things that I especially like about these particular boards is that all of the pins are clearly labeled on both sides of the circuit board. This makes prototyping much easier as you are not constantly looking at a pinout diagram and then counting pins on the board to make sure you are wiring to the correct pin. I like that the board has “FLASH” and “RST” buttons, and they are clearly labeled. All labeling is silk screened onto the circuit board, and appears to be quite durable. For those who have not used ESP-12E modules, there is a blue LED next to the antenna on the actual ESP-12E. This LED is primarily there as an indicator that the board is communicating serially with the PC, so you should see it flashing when you are downloading a program or using serial communication with the board. This LED is actually connected to GPIO2, so if you configure that pin to be an output then you can also turn the LED ‘ON’ and ‘OFF’ with your program. It is a great way to flash status codes from your prototype program. I know this review is long, but it is the type of information I look for when deciding whether or not to buy something I am considering buying. ... show more

  • Finally got it to work!
Color: 2pcs CP2102
This product suffers from a severe lack of documentation. After days of fiddling I have finally gotten it to work with the Arduino environment. To help those who are having problems, here are the steps necessary to make it work with the Arduino programming environment. 1) Download the latest Arduino environment (use Google). I am using 1.8.3 on Windows 7. 2) Follow the guide on sparkfun regarding installing the 8266 in the arduino environment. Google "sparkfun installing 8266 guide" and it should be the top link. 3) You must also have the Silicon Labs CP210x USB to UART Bridge driver installed (probably need to reboot). It is available for most major OS's. Use Google to find the driver. Verify that (in windows) your Device Manager lists this driver in the PORTS part of the tree. It will also show your COM port for your ESP8266 next to it. If it doesn't show, then nothing else will work. 4) Now in the Tools menu you will need to setup for your board. Everything after this is under the Tools menu in the Arduino environment. Set Board -> Generic ESP8266 Module Set Flash Mode -> DOUT Leave Upload Speed -> 115200 6) Hold the flash button on the board while uploading the code from the Arduino environment. I suggest the back side of a pencil since you will be holding it a while. 7) Click reset on the board to start the program. Here is a sample blink program I know works and blinks the blue LED on the board its self. One last tip, the labels for the pins are correct on the bottom of the board, but oddly the top of the board does not seem to map correctly (might be me not understanding why D0 is supposed to equal GPIO16). So GPIO0 on the bottom is actuated by digitalWrite(0,HIGH) in the code. int PIN = 2; void setup() { pinMode(PIN, OUTPUT); digitalWrite(PIN, LOW); } void loop() { digitalWrite(PIN, HIGH); delay(1000); digitalWrite(PIN, LOW); delay(1000); } ... show more

  • Great boards!! Once you figure them out...
These boards are an incredible value!! Having the integrated Wifi makes building IOT projects extremely easy to complete. There are a couple of issues that I struggled with at first: - The pin numbers are a little confusing, when programming using the Arduino IDE insert this code at the beginning of your sketch to convert from the Dx pin numbers printed on the board to pin numbers that Arduino recognizes. //ESP 8266 PIN OUTS #define D0 16 #define D1 5 // I2C Bus SCL (clock) #define D2 4 // I2C Bus SDA (data) #define D3 0 #define D4 2 // Same as "LED_BUILTIN", but inverted logic #define D5 14 // SPI Bus SCK (clock) #define D6 12 // SPI Bus MISO #define D7 13 // SPI Bus MOSI #define D8 15 // SPI Bus SS (CS) #define D9 3 // RX0 (Serial console) #define D10 1 // TX0 (Serial console) - In addition, the V3 boards are too wide to use on a standard width breadboard. If you use two breadboards side by side you can solve this problem and have plenty of space for your projects. I have attached a photo that shows how I did it. ... show more
