ESP32 30-Pin/38-Pin WIFI Bluetooth Module IOT NODE-MCU32 Node MCU NodeMCU ESP32S Node MCU Node-MCU32S WROOM 32 CP2102

Description:
 It was meant to be used as a Wi-Fi bridge for other microcontrollers until someone noticed it had way more processing power and memory than those other microcontrollers. The SDK went public and a hacker (Ivan Grokhotkov, now working for Espressif) released a project to support the ESP8266 from within the Arduino IDE. And as they say in the books the rest is history.

Even though the ESP8266 has some limitations that could be overlooked, its huge success led to a bigger problem: security. There are literally hundreds of home appliances running on an ESP8266, from smart switches to smart light bulbs to LED drivers or even mosquito killers. And the ESP8266 does not provide any means to secure the code or the data it stores. Anyone with physical access to the device can read your more sensitive information, such as Wi-Fi credentials.

Specification :

- Chip: Dual Mode with 2.4 GHz Wi-Fi + Bluetooth
- Support 3 Modes:  AP STA, AP+STA coexistence mode
- Work Perfectly with Arduino IDE.
- Power Consumption: Low
- Safe, reliable and scalable to variety of applications
- Support LWIP protocol, freertos

Features:
1.Applicable to ESP32-DevKitC (30P) series expansion board
2.Extensive compatibility: Please confirm that the pin width of your esp32 board matches the pin width of the leakage board
3.The module is safe, reliable, expandable and suitable for various applications.
4.Support DC (6.5-12V) power supply or USB (5V) power supply, stable and reliable, providing good contact and stable signal transmission for your esp32 board
5.Expanding GVS interface facilitates access to various electronic module sensors, while creatively designing JUMP interface, which is very useful for you to reuse all pins, and is very suitable for users to reuse all pins in diy projects.
