About this product

DESCRIPTION

The ESP8266 NodeMCU V1.0 ESP-12E WiFi module is the latest version of this popular module and can be used as a WiFi enabled replacement for an Arduino in many applications.

KEY FEATURES OF ESP8266 NODEMCU V1.0 ESP-12E MODULE:

Besides adding WiFi capability, the main claim to fame for the ESP8266 processor over the AVR processor of the standard Arduino is that it has a larger 4 MB of Flash memory and runs at clock speeds of 80 MHz and can sometimes optionally be overclocked to 160 MHz and therefore has a very fast processing speed.

The Digital I/O all support PWM and interrupts. In addition they can be configured to have pull-up or pull-down resistors. Though there are 11 digital I/O pins, 2 are typically reserved for use as the TX/RX lines if serial communications are used which leaves 9 digital I/O.

On the down-side, it has only 1 analog input which is probably the most significant limitation for some sensor type applications. That can always be overcome by using an external Analog Mux module like our 16-channel 74HC4067 or our ADS1115 4-channel 16-bit ADC module below if more analog I/O is desired.

The module can be powered via the USB port or by using an external 7-12V power supply connected to the VIN pin. The module runs at 3.3V, so keep that in mind when working with I/O. The digital I/O is stated as being 5V tolerant, but the analog input needs to be limited to < 3.3V.

The blue on-board LED is connected to D0 (GPIO16) and can be accessed using the LED_BUILTIN constant.

The module has a typical ‘Reset’ button as well as a ‘Flash’ button. The Flash button is used when programming using the original NodeMCU firmware. If the module is being used with the Arduino IDE, the Flash button does not…
