3.3V power supply module, power up and go! Also don’t have EN chip enable pin, more simple to use. Can NOT be powered by 5V.
Up to 6 control relays, sensor support, OLED screen
IIC interface via GPIO pin 4 and 5
Firmware: We-chat airkiss smart config interface, can configure the module in a minute.
The board can vertical soldering embedded onto your board, just make a 1mm groove, and soldering board in. Antenna align to top, very well signal strength get.
Note:
2.54mm SMD pad pin, not very easy to soldering, but very ready for real project.
Each purchase if for one piece of the esp8285 main board only, not include the relay board in attached image.
