Description

ESP8266 WiFi Board for IoT Projects

CAUTION!!!!!
This board has exposed high voltage AC tracks and should not be programmed while plugged into mains voltage. Any fault on the board can cause serious damage to your computer.
Do not supply this unit with mains while any USB-TTL programmer is plugged in or while the board is not secured and enclosed in the provided enclosure.

 

Hardware Features
Based on the ESP-12F ESP8266 Wifi module.
802.11 b/g/n Wifi.
Integrated low power 32-bit MCU.
4MB Flash.
On-board AC-DC power module (85 - 265VAC).
Relay: Songle 10A 250VAC/30VDC SPDT Relay.
Enclosure: 111 x 42mm.
Two on-board buttons.
Two on-board LEDs.
Some of the ESP8266 module's pins is available on-board.
Reserved footprint for a DHT22 sensor (recommended to mount DHT sensor outside the enclosure).

The ESP8266 can be programmed using our CP2102 USB-TTL programmer that can be found here.
Supported in Tasmota firmware (Select Electrodragon in configuration). Other firmware may also be used but may require additional setup.

The cables on the output terminals conflicts with the enclosure, check cable routing.

This relay board does not pass the AC input to the output relays.

Series of ESP Relay Boards:
Wifi IoT Relay Board: AC Mains Power ON/OFF
ESP Relay Board IL: Optimize for inductive loads
Wifi IoT Relay Board VDC: DC Power Supply, DC (or AC) ON/OFF
Wifi IoT Relay Board SPDT: Output not connected to input), DC or AC On/OFF
ESP LED Strip Board: Similar to H801 Control for LED strips (4 x MosFET)

Difference of this version (SPST) and SPDT version:
The output of the SPST relay is the same as the AC main input voltage. The relay only acts as an inline AC switch.
The output of the SPDT relay is not connected to the AC mains input voltage, the relay can act as a switch for any other circuit, can be either AC or DC power.
