Hi Everyone,
Initially, I modified few WIFI switch to reflash it with my own firmware but I want more feature.
Almost of them was based on the ESP8688 family. I wanted to have a board where I can fix it on the DIN rail, looks good and professional.
I also want to have several outputs and an extension possibility thought and I2C GPIO. So, I created my own Arduino Compatible relay board.
The first prototype was based on ESP32 S3 dev module with a 6Xrelay board. So, it didn't look pretty and it want to have an external power supply.
I used it 4 months before create my own relay PCB for this project.
The second prototype 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
I use it with my custom growth light system since 6 month without issue.
The source code and the documentation are available on my Github page(https://github.com/CyberSerre) .
I provide 2 basic examples where I use the MQTT protocol to control light.
Cheer :D
