Hello everyone.
Please tell me the difference between ESP-WROOM-02 and ESP-WROOM-02D.
It is said that ESP-WROOM-02D improved the performance of wireless, but how did it improve specifically?

I see that there's a price difference too: 02D has a higher price everywhere on the market. On the U and D modules, there is also an additional resistor. There's also an archived sample with the ESP-WROOM-02D and ESP-WROOM-02U writemyessay review if you are interested.
