What is the acceptable tolerance of the input voltage for the KC868-A32?

1. install zigbee2mqtt
https://github.com/zigbee2mqtt/hassio-zigbee2mqtt

2. add config zigbee2mqtt
   
serial:
  port: tcp://192.168.1.201:6638
  adapter: ezsp

3. config (Zigbee Home Automation) ZHA

socket://192.168.1.201:6638
band: 115200
   
   

hi

i have kc868-h32bs v1.39 . 
i'm trying to upgrade the firmware . 
i downloaded KC868 Controller Bootloader and used serial to usb cable to upgrade but every time i run it i get error 
is there a way to upgrade using ethernet? if not what's the solution

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.

Hi guys,

before use source code, make sure you have set the serial2 pin number by config file.

Goodnight,

I'm having trouble using the codes to use the PCF8574 of the KC868 A8, using the same code for input and output, I noticed that it already comes with the standard Digital Input 1 > Turn on > Digital Output 1, does anyone have this code so I can work above him?

Thank you very much in advance
