ESP32-WROOM-32E (ESP32-DEVKITC-32E) is an evaluation board with ESP32 processor, 4MB FLASH, 802.11 a/b/g/n (Wi-Fi, WiFi, WLAN) and BlueTooth® Smart Ready 4.x dual-mode. It is much faster than the ESP8266 processor (NodeMCU and similar), and very easy to use.

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.

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.

TinyS3 is the latest in Unexpected Maker's popular range of "Tiny" development boards. It's packed with amazing features and peripherals, wireless connectivity, and stacks of Flash and PSRAM, all in the same tiny package size as the original TinyPICO!

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.
