KinCony F4 4CH ESP32-S3 Removable Relay board

KinCony F4 ESP32 smart controller based on ESP32-S3-WROOM-1U (N16R8) wifi chip. It have 4 manual control switch buttons can turn ON/OFF relay even if system is broken. 4 channel removable OMRON high-quality relay, 4 channel 1-wire GPIOs, 2 free GPIOs, 4 channel analog input ports. One SD card using SPI bus. KinCony F4 include DS3231 high precision RTC clock chip. LCD display will show wifi and ethernet IP address and Tuya connection state. F4 have RS485 port and RF433MHz RF receiver. You can write any code by Arduino IDE / MicroPython / ESP-IDF development tool to ESP32 module. We will supply Arduino / ESP-IDF 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(tasmota total support MAX 32channel INPUT+OUTPUT ports) for smart home automation DIY. F4 use KCS v3 firmware, it support home assistant auto discovery function by MQTT, so without write any config code (zero code) for home assistant.

Model No. KinCony F4
Description: KinCony 4 Channel ESP32-S3 Removable Relay Controller – F4
Power supply: 12/24V DC (Default install by 12V OMRON relay)
Processor: ESP32-S3-WROOM-1U (N16R8)
Size: 138mm*127mm*65mm
interfaces: Ethernet(RJ45)-LAN 100Mbps IPv4/IPv6,WiFi,RS485,Bluetooth,USB-C,LCD,Tuya Module
RTC: DS3231 high precision chip (battery socket on PCB)
SD Card: SPI bus
Installation method: DIN RAIL
LCD: SSD1306 I2C display

Outputs:
4CH OMRON removable relay, every channel have “COM”(common) and “NO”(normal open) ports.
MAX load 250VAC/16A 30VDC/16A

Inputs:
2CH analog input DC0-5V (A1,A2) 2CH analog input 4-20mA (A3,A4)
4CH dry contact inputs (optocoupler isolation, long distance circuit for MAX 500 meters cable)
3 buttons: 1:ESP32 Reset 2:ESP32 Download 3:Tuya config
1-Wire GPIO: 4CH (with pull-up resistance on PCB)
free GPIO: 2CH (without pull-up resistance on PCB, connect with ESP32 pin directly)
RF receiver socket: 433MHz RF receiver

software solution:

1. download KinCony KCS firmware, so that work with multi protocol: HTTP, MQTT, TCP, RS485 modbus, Tuya app, config OUTPUT for “momentary” and “interlock” group functions. use Tuya mobile phone app directly, support voice control by Alexa and Google home speaker directly. “KCS” support IFTTT function work locally without internet. It also support use by KinCony cloud server. KCS v3 support home assistant auto discovery function by MQTT, so without any config file for home assistant.

2. download firmware by ESPHome, integrate to home assistant or use by web service.

3. download tasmota firmware.

4. write your own arudino code for your own requirements.

5. It is recommended to use home assistant and Tuya mobile phone app at the same time. So that remote control by internet using Tuya app, local control by LAN using home assistant app.
