Mature and stable ESP-12f WiFi module on board capacity 4mbyte flash
IO port and UART download port of WiFi module are all led out to facilitate secondary development
The power supply mode supports DC24 v
reset on and a programmable on for the onboard WiFi module
Esp-12f supports the use of for LDE and other development tools and provides reference programs under for development environment

On board 16 channel 24 V 10 a relay output switch signal suitable for controlling the load whose working voltage is within AC 250 V DC 30 v
On board power indicator relay indicator module with LED
Two on-board shift registers 74HC595 control the relay switch
The 16 way relay is controlled by two 74HC595 cascades so the corresponding control of 595 is needed to open and the relay The reference has been provided
Burning and writing port GND TX and 33V of esp8266 are respectively connected with GND TX and 33V of external TTL serial port module IO0 needs to be connected with GND when downloading and then disconnect IO0 and GND after downloading
