  KC868-A4S 4G esp32 arduino relay board Released
Posted by: admin - 03-01-2023, 06:15 AM - Forum: News - No Replies

KC868-A4S esp32 arduino board based on ESP32 wifi chip, many hardware resource for you to use. it support GSM module for SMS, voice call, GPRS communication. Use SMS or call to turn ON/OFF relay will be very easy for home automation DIY. It also have 8 channel dimmer output and PWM output extender. You can write any code by Arduino IDE to ESP32 wifi/bluetooth/ethernet RS485 module. We will supply demo code for different samples. Everyone can modify and change the code for your own smart home automation system project. it support use by ESPHome for home assistant or tasmota firmware for smart home automation DIY.

  How to choose the right microcontroller/controller before starting the development of
Posted by: dedbless - 03-01-2023, 05:36 AM - Forum: DIY Project - Replies (2)

Hi guys,

I have started searching for some information about the microcontrollers/controllers with which I can develop my own controller and the SMART-house. It is needed for my research work. I am new to this, and it is hard for me to find the necessary information.
I have found that such controllers as Arduino, Raspberry PI, ESP32, etc can be used.
However, how can I find the model of the controller which can suit my requirements? They are the following:
2-stage building with a garage (so it is +-400 sq.m.) with some number of SMART devices that are responsible for security (cameras, fire alarm, etc), temperature control, radiators, leakage control, opening/closing control, etc.
I am interested in the hardware area at first.
Any advices, links to the resources, researches, and articles with a similar topic will be really appreciated.
PS: sorry for my not clear English (just in case)
Thank you in advance.
