In the schematics of ESP-WROOM-02D the antenna filter is designed differently (with a higher incudance) than the one on the ESP-WROOM-02 board. Also the VDD33 rail uses a different type of filter (with an inductor and a capacitor instead of pure capacitive smoothing) on the ESP-WROOM-02D.

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?
