The term “NodeMCU” by default refers to the firmware rather than the development kits. It includes firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which is based on the ESP-12 module. Espressif’s official modules are presently ESP-WROOM-02 and ESP-WROOM-S2. Some of these modules have specific identifiers, including monikers such as “ESP-WROOM-02” and and “ESP-01” through “ESP-14” while other modules might be ill-labeled and merely referred to by a general description - e.g., “ESP8266 Wireless Transceiver.” ESP8266-based modules have demonstrated themselves as a capable, low-cost, networkable foundation for facilitating end-point IoT developments. Vendors have consequently created a multitude of compact printed circuit board modules based around the ESP8266 chip. Read about For Overview, Datasheet, Technical Reference.ĮSP8285 is a variation of ESP8266 with 1 MiB of embedded flash memory. The silicon chip itself is housed within a 5 mm × 5 mm Quad Flat No-Leads package with 33 connection pads - 8 pads along each side and one large thermal/ground pad in the center. (Also, 32 KiB instruction cache RAM and 16 KiB ETS system data RAM.) External flash memory can be accessed through SPI. It has a 64 KiB boot ROM, 32 KiB instruction RAM, and 80 KiB user data RAM. The processor core, called “L106” by Espressif, is based on Tensilica’s Diamond Standard 106Micro 32-bit processor controller core and runs at 80 MHz (or overclocked to 160 MHz).

It provides capabilities for 2.4 GHz Wi-Fi (802.11 b/g/n, supporting WPA/WPA2), general-purpose input/output (16 GPIO), Inter-Integrated Circuit (I☬), analog-to-digital conversion (10-bit ADC), Serial Peripheral Interface (SPI), I²S interfaces with DMA (sharing pins with GPIO), UART (on dedicated pins, plus a transmit-only UART can be enabled on GPIO2), and pulse-width modulation (PWM).
ESP8266 SERIAL PORT 0 GPIO SERIES
The ESP8266 series presently includes the ESP8266EX and ESP8285 chips.ĮSP8266EX (simply referred to as ESP8266) is a system-on-chip (SoC) which integrates a 32-bit Tensilica microcontroller, standard digital peripheral interfaces, antenna switches, RF balun, power amplifier, low noise receive amplifier, filters and power management modules into a small package.
The ESP8266 series, or family, of Wi-Fi chips is produced by Espressif Systems, a fabless semiconductor company operating out of Shanghai, China. The term “NodeMCU” by default refers to the firmware rather than the dev kits. Use of ESP8266 as just a Serial-to-WiFi bridge with arduino is most common mistake newbies do. ESP8266 comes in many variants most popular is ESP-12 and ESP-01. ESP8266 is most popular development board.
