ESP8266 serial WIFI NODEMCU

ESP8266 serial WIFI NODEMCU

• Development of the basic API for ESP8266 serial WIFI NODEMCU.
• The Nodemcu is compatible with a wide range of devices.
• The Arduino is compatible with the duino IDE, making it possible to program using Ar.
• I am in favor of a playful and comical cloud form.
• Ali cloud is gearing up to release new firmware.

Fundamental characteristics of ESP8266 serial WIFI NODEMCU:

• The operating temperature ranges from -20 to 70 degrees Celsius.
• The L106 is a CPU designed by Tensilica.
• The available RAM is 36KB.
• 32 Mbit of flash memory
• That specific system
• 802.11b/g/n, also referred to as Wi-Fi technology, combines the best features of previous wireless protocols into a single standard.
• The device features a Tensilica L106 ultra-low power 32-bit micro MCU, operating at 80 MHz and 160 MHz in 16-bit aerodynamic mode.
• MHz, compatible with RTOS
• The WIFI connection operates at 2.4GHz and offers support for the WPA/WPA2 security mode.
• The device features a 10 bit high precision ADC that is built-in.
• The TCP / IP protocol stack within the system
• The device includes a built-in TR switch, balun, power amplifier, and matching network.
• The internal components, including the PLL, regulator, and power management, enable a 20 dBm output power in 802.11b mode.
• The feature promotes the use of antenna diversity.
• The device enters a state of deep sleep, with a current of 20uA, while its shutdown current remains under 5uA.
• The application processor has the capability to function as SDIO 2.0, SPI, or UART, providing added versatility.
• Techniques such as STBC, 1×1 MIMO, and 2×1 MIMO are commonly used to enhance wireless connectivity, along with A-MPDU and A-MSDU aggregation. Additionally, a guard interval of 0.4 s is often implemented for improved performance.
• Rise and make the connection through the package and switch within 2ms.
• The standby power consumption for DTIM3 is less than 1.0 mW.
• Upgrade can be performed remotely or through cloud OTA technology.
• This device is capable of operating in both STA, AP, and mixed STA/AP mode.
