- Based on ESP8266 Wifi IC, ESP-12F module.
- This is the extended version of esp relay board. Flashed also the same firmware and use the same case.
- SPDT 5 pins relay, Songle 10A/250VAC/30VDC, NOT connected to the AC mains. Three states: normally ON, normally OFF and Common pin.
- Input 65-265 VAC board voltage supply, use professional and well tested power module.
- Note on the relay side, terminal pin pitch is 3.5mm, still little conflict with case. Terminal pin pitch on input voltage side is still 5.08m.
- Not including screws for less than 5 kits from December 2017 (Which cause shaky sounds inside and will trigger security failure of shipment, it significally delay shipment.)
- Please prepare M2*8 or M2.2*6, etc crews by yourself.
