ESP-12F ESP8266 12F WiFi Board Module

The ESP32-CAM is a camera module with the ESP32-S chip. It features an OV2640 camera, several GPIOs to connect peripherals, and microSD card slot.

You can easily control any device over the Internet through your phone, computer, etc.
The module can handle 5 users at the same time, it can work in two modes: STA (client) and AP (access point).
In AP mode, the module is connected via WIFI directly to your phone or computer (in open field can be up to 300 meters).
In STA mode, the relay module is connected to the access point (router) that supplies the network.
Wi-Fi in the room where the relays are located. In this case, the range mainly depends on the power of the access point antennas (routers).
You should not turn off after the configuration is completed, as some of the parameters of the WIFI module cannot be saved when power is cut off.

SparkFun IoT RedBoard development board compatible with Arduino. It incorporates an ESP32 chip with a 32-bit dual-core Xtensa LX6 microprocessor with a clock frequency of up to 240 MHz. It enables WiFi and Bluetooth wireless communication, making it versatile for Smart Home and IoT projects.

The SparkFun WiFi ESP8266 Shield is a shield for Arduino R3 R3 board enabling internet connection. ESP8266 as you all know is a solid fundament for any IoT project an in this version it can be simply and easily put on your board. It is a great middle ground between the sole module and the development board such NodeMcu or WeMos. So if you need a relatively cheap and super reliable way to internet for your Arduino project - this is the shield for you! ESP8266 shield WiFi comes with an AT-command firmware, hence can be controlled by any UART. It works great with any Arduino R· layout. The shield doesn´t have the headers on.

TUYA IoT interface module - you will be able to control your projects IoT Internet of Things interface of your Arduino. Tuya interface that allows you to control outputs of the Arduino module via WiFi network using apps for Android and iOS mobile devices. The device communicates with Arduino via UART interface, powered by 5V.
