ESP32-S3 16 channel GPIO module – KC868-A16v3 – Smart Home Automation

KinCony KC868-A16v3 ESP32-S3 smart controller based on ESP32-S3-WROOM-1U (N16R8) wifi chip. It have 16 channel digital input and 16 channel digital output, 3 channel 1-wire GPIOs, 4 channel analog input ports. 3 free GPIO on PCB beside ESP32-S3 module. One SD card using SPI bus. KinCony KC868-A16v3 include DS3231 high precision RTC clock chip. LCD display will show wifi and ethernet IP address. A16v3 have RS485 port and RF433MHz RF sender / 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 for smart home automation DIY. A16v3 use KCS v3 firmware, it support home assistant auto discovery function by MQTT, so without write any config code (zero code) for home assistant. KCS v3 support Apple HomeKit.

improvements based on old KC868-A16:

1. use by ESP32-S3-WROOM-1U (N16R8) big memory size chip. support extend wifi antenna by IPEX port.
2. add NTC power protect circuit, if polar exchange will not burn board.
3. replace LAN8720A with W5500 ethernet chip, more stable.
4. fixed RF receiver circuit bug.
5. add DS3231 high-precision RTC clock.
6. support KinCony new cloud service.
7. support KCS v3 support Apple HomeKit and Loxone Miniserver system.
8. add SSD1306 LCD display
9. add SD card to save LOG
10. support KCS v3 newest firmware more powerful functions.

software solution:

1. download KinCony KCS v3 firmware, so that work with multi protocol: HTTP, MQTT, TCP, RS485 modbus, Tuya app (need to buy tuya license), config OUTPUT for “momentary” and “interlock” group functions. “KCS” v3 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.
