485T,This is a T-shape connector for RS485 communication, which can apply to point to point, one point to multi-point connection, plus a POWER LED for indication. The terminal connector specification is 4pin HT3.96. Many M5 products sharing this type of connector, such as PLC, Base26, HAT-RS485, etc.
I have not yet proceeded to the project, but I hope I will not be disappointed. Thanks for quick delivery.
Started with the 485 example and had working communication in a very short time!
