USB Cable

Posted by: bob_tm - 08-01-2025, 12:06 PM - Forum: KC868-A16v3 - No Replies

For everyone, who spend hours to get first flash.

Modern type-c to type-c cables do not work with this board! Cheap or expensive - mine do not work at all.

I cut some cheap type c cable and measure connection between data lines and ESP contacts - only one line is connected. Other data line goes to unsoldered pin in type c socket! But in old big USB - both lines going to ESP32.

The only option that works for me - type C / type A cable with type A / type C adapter.

Hope this save time for somebody.

KinCony T64M Tiny ESP32 Smart Controller released

Posted by: admin - 08-01-2025, 04:56 AM - Forum: News - Replies (2)

KinCony T64M tiny ESP32 smart controller based on ESP32-S3-WROOM-1U (N16R8) wifi chip. Support 64 channel MOSFET output, 4 channel 1-wire GPIOs, 3 channel free GPIOs. T64M have RS485 port. You can write any code by Arduino IDE / Micro Python / 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. T64M 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 KinCony cloud service (official shop customer free 2 years), remote monitor and control device by webpage in anywhere. KCS v3 support KinCony board integrate to Loxone Miniserver. Support Apple HomeKit for Siri.

Code:
/*

 *

 * This program reads 24 input states from two PCF8575 I/O expanders and

 * When the input pin is HIGH, the corresponding relay is turned OFF.

[arduino code examples for B24M]-09 how to communication with Tuya WiFi module

Code:
/*

 * Made by KinCony IoT: https://www.kincony.com

 * 

 * This Arduino program implements communication between ESP32 and the Tuya module

 * via UART (serial communication). It listens for specific packets from the Tuya module

 * and responds according to the predefined commands.

 * 

 * Functionality:

 * 1. When the ESP32 receives a heartbeat packet (55 AA 00 00 00 00 FF),

 *    it sends a heartbeat response (55 AA 03 00 00 01 00 03).

 * 2. When the ESP32 receives a product information request (55 AA 00 01 00 00 00),

 *    it sends a product information response (55 AA 03 01 ...).

 * 3. When the ESP32 receives a work mode request (55 AA 00 02 00 00 01),

 *    it sends a work mode response (55 AA 03 02 00 03 10 1C 14 47).

 * 4. When the ESP32 receives a network status request (55 AA 00 03 00 01 00 03),

 *    it sends a network status response (55 AA 03 03 00 00 05).

 * 5. Subsequent heartbeat packets (55 AA 00 00 00 00 FF) are responded to with

 *    (55 AA 03 00 00 01 01 04).
