Review: it's a relay.. and it just works. - I used these connected to an ESP32 dev board running ESPHome to control various buttons in my house through home assistant. For one, I wired the garage door opener button through the relay and I can remotely press the garage door opener button now. For another one, I wired my old analog door bell chime through the relay and I can trigger the doorbell chime through an automation when someone presses the doorbell button on my smart doorbell. What can I say, 3.3v relay is useful when you have 3.3v microcontrollers.
Review: Exactly what I needed - Good value without having to buy more than I need. Worked great for a Raspberry pi project that was controlling 12VDC devices. Quality and workmanship of the board was also very good
