Teardown of this relay (no longer available? I ordered it on 06.10.24)
Main board: FL-S63-V2.1
Relay: Yongwei Y3F-105DM 10A 250V
Little extra can be said about this one, as there are many similar devices.
The only notable things is that it uses ESP8266 and contains extra joints for TYLC4 or TYWE2L (or their beken analogues).
No pins, and i will later replace TYLC5 with ESP8684-WROOM-05 for personal consistency.
