News: ESP32-DevKitC Smart Home Expansion Board NTC Temperature Collection Current Voltage Input Output Relay Switch For Arduino MQTT ES32G15

ES32G15 is an expansion board for ESP32-DevKitC. It comes with a wealth of expansion resources, including but not limited to: NTC AI AO DI DO. With the programmable properties of ESP32, it can be used as a simple PLC or a WIFI-based smart home development kit.



1 Working voltage: Wide voltage DC 12-28V

2 Working Current : Standby current 15MA, 1 relay open 50MA, 2 relays open 85MA, 3 relays open 120MA, 4 relays open 155MA

3 size 121*72*19mm(Only Board)

4 Weight : 95g(Only Board), 186g(with shell)

 

Onboard Resources

2CH 0/4-20MA Current Output

2CH 0-5V/10V Voltage Output

2CH 0/4-20MA Current Input

2CH 0-5V/10V Voltage Input

4CH 10K NTC Input(Any B value)

4CH NPN Digital Input

4CH 10A Relay Output

As long as you write ESP32 code,You can use it to achieve a variety of delay timer function,such as:

WIFI Remote control switch

WIFI Current and voltage collection

RS485 Master-Slave Device(PLC MCU),

2x 0-5V/10V Voltage Output(OR 2x 0/4-20MA Current Output)

2x 0/4-20MA Current Collection,

2x 0-5V/10V Voltage Collection,

4x Temperature collection(External 10K NTC sensor)

MQTT,HTTP,WEB Remote control switch

Motor forward and reverse,

Timing on,

Timing off,

Power-up delay,

Trigger delay,

Infinite loop delay,

A finite number of cyclic delays,

Power sequencer,

And so on.

 

This is an expansion board based on 38PIN ESP32(ESP32-DevKitC). We only provide some Arduiuo codes for testing the hardware. More codes and functions need to be developed by yourself.

If you need more functionality, write your own code. We do not provide additional code and technical support

 

 

Note: ES32G15 can not work independently, must be under the control of the 38PIN ESP32 board to work,If you do not have a 38PIN ESP32 board, purchase it separately or purchase a kit with 38PIN ESP32
