K868-A16 433 RF MHz receiver

[Razvan]

Today I installed the new 433 Mhz RF reception and transmission modules. Unfortunately the same result, I can not see any code in the log inside K868-A16 with ESPHome.

I also took measurements. When I do not press any button on the remote control, the voltage is almost 0.014 V. When I press any button on the remote control, the voltage remains the same, it does not change.

I think there's something wrong with this board. It's hard for me to believe that the new RF module is also defective.

This is my configuration.
