Sorry but why are you wasting our time with a pointless video of flashing lights and music? Please post a proper tutorial with ALL the configurations required ALL the code!

Is there a how-to anywhere ? The manual doesn't help me at all : you need 2 units, the code is very outdated (old python, not compatible), and there is little explanation or a practical example on how to communicate with a real-life RS485 device. Anyone have a link to a good how-to doc or video ?

I find it silly that nowhere in the manual or in any of the marketing material do they remind user to connect common ground. Raspberry Pi's most definitely are not always properly grounded to earth. Notice earth wire in this video. A hobbyist end user might end up not connecting grounds together between devices because the terminal only has pinouts for CAN high/low.

Yep the documentaion is very bad. How to use the Pins to get DMX signals.

Hi, Is there any way to troubleshoot the board? Like which inputs should be toggling and if there's a sequence by which they do so? Thanks

HI, how i can set modbus device address on the board?

Can this module use in Raspberry Pi 4 Model B
