Have any of you come across such a circuit to buy? This is dismantled from a wifi bulb. . . .

You need to remove the sticker and then write down the designation of the WiFi module. For what purpose do you want to buy it?

I am looking for a small circuit to make a light switch. I would like to connect this circuit to MQTT. I realise there are off-the-shelf solutions from Tuya etc, but I'm rather interested in something minimalist that I can handle in the aforementioned way.

NiceMCU is cheap, you might even buy one for £5: NiceMCU XH-WB3S BK7238 tutorial - quick start, flashing, sensors, MQTT and Home Assistant . I don't know if you'll get that module there specifically, much less at a low price. Plus you still haven't shown what module sits there, you have to remove the sticker. Or is it better to buy and flash a ready-made one? ZN268131 WiFi Smart Switch which allows you to connect a bistable button . How about just some ESP + PlatformIO? Added after 35 : ESP8266 and Tasmota - WiFi relay control step-by-step .

I have set up on Shelly1, whereas I do not know how to configure MQTT, or in other words whether I am configuring it correctly. I enter the broker server as: h000000.ala.us-east-1.emqxsl.com, well, and actually I don't know if it connects or not.... I look at the server and I have no such client. What am I doing wrong? .

Where to find the electronic circuitry from a WiFi light bulb?

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:
