Hi,
anybody has any experience in controlling this I2C device (purchased at AliExpress) using Arduino?
I'm using an ESP32 WROOM and can control another I2C relay board but I'm unable to find what library to use for this one...
Thx!!!
ps: it looks like this 
Sorry!!!!!!!!!!!!!
I found it already!!!
It listens to the PCAL9535A library...for those who need it, you can find library and examples at: GitHub - chrissbarr/PCAL9535A-Arduino-Library: An Arduino library for the PCAL9535A GPIO Expander IC
Many thanks to Chris Barr!
