The Development Kit based on ESP8266, integates GPIO, PWM, IIC, 1-Wire and ADC all in one board.

Power your developement in the fastest way combinating with NodeMCU Firmware!

• USB-TTL included, plug&play

• 10 GPIO, every GPIO can be PWM, I2C, 1-wire

• FCC CERTIFIED WI-FI module(Coming soon)

• PCB antenna

Attention : Le module ne délivre que du 3.3 v en sortie.

Les modules MFRC522 sont donc compatibles.

Preparer l'IDE Arduino

Select the MENU option Tools → Board → Boards Manager…and scroll down and to locate the option esp8266 by ESP8266 Community which should be the last item on the list, and click INSTALL

• Installing The USB Drivers: The USB to Serial UART module included on the board is the Silicon Labs’ CP2012, for which we usually need to install the readily available Virtual COM Port (VCP) drivers. In the case of my MAC, the device file created to communicate with the CP2102 has the name/dev/cu.SLAB_USBtoUART. You can find the appropriate drive for your computer at following link: CP210x USB to UART Bridge VCP Drivers
• After restarting the Arduino IDE we can now select the board we’re using from the menu option Tools → Board → NodeMCU 1.0 (ESP-12E Module).Then, we specify the correct CPU Frequency (Tools → CPU Frequency: “” → 80MHz) and Upload Speed (Tools → Upload Speed: “” → 115200). Finally, the last step is to select the correct option for the Port (Tools → Port → /dev/cu.SLAB_USBtoUART).

J'ai testé les librairies Adafruit et OLED des précédents articles, elles ne sont pas compatibles avec un ESP12E, d'ou une nouvelle librairie.
