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!

ESP32-S3-DevKitC-1-N8R2 general-purpose development board based on the ESP32-S3R2-WROOM-1 chip, Flash 8MB, PSRAM 2MB.

ESP8266 Thing Dev board from Sparkfun is a reliable, strong solution for IoT projects. The ESP8266 is a well-known WiFi controller from the boards such as NodeMcu and or WeMos. This board increases the reliability to maximum though. This version comes without headers.

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.
