32 channel 4G ESP32 relay board

KinCony A32 Pro ESP32 relay board based on ESP32-S3-WROOM-1U (N16R8) wifi chip, it have 32 manual control switch buttons can turn ON/OFF relay even if system is broken. Support 32 channel relay output and 2 channel dc 0-10v dimmer output, 2 channel 1-wire GPIOs, 4 channel analog input ports. It support 4G module (SIM7600 series) for SMS, voice call, GPRS communication for Tuya mobile application. SIM7600 module also support GPS, just need connect IPEX extender GPS antena. Download KCS firmware , use SMS or call to turn ON/OFF relay will be very easy for home automation DIY. LCD display will show wifi and ethernet IP address and 4G connection state and Tuya connection state. You can write any code by Arduino IDE / MicroPython / ESP-IDF development tool to ESP32 module. We will supply arduino 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 (Note: tasmota support INPUT + OUTPUT total 32 channel) for smart home automation DIY.

Model No. KinCony A32 Pro
Description: KinCony 32 Channel ESP32-S3 Relay Controller – A32 Pro
Power supply: 12V DC
Processor: ESP32-S3-WROOM-1U (N16R8)
PCB Size: 250mm*122mm
interfaces: Ethernet(RJ45)-LAN 100Mbps IPv4/IPv6,WiFi,RS485,Bluetooth,USB,SIM7600 Series 4G Module(optional),LCD,RF433MHz Receiver

Outputs:
32CH Relay Outputs, every channel have “COM,NO”:250VAC 7A
2CH 0-10v dc

Inputs:
Inputs 2 analog input DC 0-5V (AI1,AI2)
2 analog input 4-20mA (AI3,AI4)
40 channel dry contact inputs
32 manual control buttons
3 buttons: S1:ESP32 Reset S2:ESP32 Download S3: Tuya module Reset
1-Wire GPIO: 2CH

all input signal ports use removable terminals.

32 toggle buttons work with relay’s coin, manual control relay without any software, it’s physical solution.

LCD display will show ethernet IP address , wifi IP address , 4G connection state (if installed 4G module) and Tuya cloud server connection state.

we use ESP32-S3 large memory chip and Tuya wifi module, so that Tuya application and home assistant can work at the same time. you can remote control relay by Tuya app , local control relay by home assistant software. (download KCS firmware , integreate A32 Pro controller to home assistant by MQTT)

this is PCB design details.

Bottom main board.

support install on DIN RAIL in distribution box.

software solution:

download KinCony KCS firmware, so that work with multi protocol: HTTP, MQTT, TCP, RS485 modbus, Tuya app, config relay 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.
download firmware by ESPHome, integrate to home assistant or use by web service.
write your own arudino code for your own requirements.
