They come in variety of types, I had ESP8266-based LSPA9, and CB2S-based and WB2S-based as well. They are sometimes glued well. 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: https://github.com/openshwprojects/OpenBK7231T If you like my work, support me at: https://paypal.me/openshwprojects Helpful post?
