When I saw this KL50 wifi light bulb on sale, I thought I want to grab one and see what is inside. A quick search revealed no details about the insides of filament WiFi light bulbs.
The light worked well from the start, discovering and connecting it through the WiFi was straight up. It does what it promises, quite a nice diffuse and rather warm light.
And inside:
The WiFi module is in the middle, and around it there is the power supply and LED driver.
WiFi is a MT7682 WiFi SOC (WiFi, ARM processor, RAM, Flash) . I could quickly get is up and running with a 3.3V supply and an LED at the PWM pin.
