Hi Everyone,

I designed few prototypes and board for my part time Ph.D. . For someone, I created a commercial version. I think some features could interest some other programmers:).

Initially, I modified few WIFI switch but I want more feature. Almost of them was based on the ESP8688 family. I want a board where I can fix it on the DIN rail and looks good and professional. So, my board have these features:

• ESP32 C3 based Board
• Open-Source Firmware available on our GitHub page
• Self powered, no need external power supply
• Use certified power supply (IEC, EN, UL/cUL)
• Exposed I2C, UART, EN and Flash pins
• 2.4 GHz WiFi (802.11 b/g/n)
• Bluetooth® 5 module
• 4 outputs NO SPST

The source code and the documentation are available on my Github page . I provide 2 basic examples where I use the MQTT protocol to control light. I used the prototype for 3 months before changing to the actual board for 4 months. I plan to add other boards like 30A outputs relay board, relay board with power monitoring and protection, temperature and humidity sensor and other stuff related to the greenhouse automation.

If you are interested by my project, you can follow me on Facebook or look my board here.

Cheer :D

Note: I don't receive any financial help or support from my university for my project and to develop this product.
