Xiaomi Smart Air Purifier 4 Lite - Wiki update

[smogger]

Any chance to get a bit more details about the Xiaomi Smart Air Purifier 4 Lite steps?

I am trying to get my heads around with the "power on the board" step.

I tried either power on the whole unit (3 beeps from the purifier and not connecting to my UART) - since nowhere mentioned HOW should we power on the board. And also tried directly connecting the 3V from my UART to the ESP32 chip leg (still not connecting somehow for me)

The board layout is slightly different then the previous version, so those guides doesn't really help me with the 4 Lite.

(PS: strange to me that whenever I plug the TX/RX to my UART, the power led lights up on it)

Thank you
