Alternative to Arduino Uno Wifi

Official Hardware Classic UNO WiFi Rev2
1

Hello

I'm working on a robotic project using an Arduino Uno Wifi. This board is used to receive commands from a tablet or laptop. The received commands are sent via I2C to an Arduino Mega which drives motors... I use http request to send commands : //192.168.43.132/arduino/digital/F1/

I like this board because it is simple to operate : connect to his interface 192.168.240.1. Select Wifi network. Upload the code below and it is ready to receive and transmit data.

I would like to purchase a second board but unfortunately this board is not available any more...
Is there an alternative ? As simple, as efficient as the Arduino Uno Wifi for a guy who is not an Arduino specialist and who is afraid to spend a lot of hours to understand how to configure a new board ?

Thanks for your suggestions.

void loop()
{   
  while(Wifi.available()){proc1(Wifi);}
} 

void proc1(WifiData client) {
  String command = client.readStringUntil('/');
  if (command == "digital") {
     readString = client.readStringUntil('/');
     tx1(readString); 
     client.println("Status: 200 OK\n");
  }
}

// ====== Send command to Arduino Mega
void tx1(String data)
{   data.toCharArray(txc, 17);
    Wire.beginTransmission(4); 
    Serial.println(txc);
    Wire.write(txc);           // 
    Wire.endTransmission();   
}

As far as I can tell the only thing with the rev2 that may trip you up is timers. The example code shows you how to use the networking and it's pretty darned easy compared to other platforms I've tried.

If you want to stick with the older chips you could try a wifi shield. DFRobot makes a Leonardo with a built in XBee socket and has a WifiBee that you can use instead of the XBee radios. I have some on order that should be here this week.

use esp8266 dev board like NodeMCU or Wemos D1 mini if it should handle only the networking. they can be programmed with Arduino and the sketch will be almost the same.
Uno WiFi has two MCUs one AVR base and second is the WiFi MCU ESP32. and then you connect this to Mega?
