MCS-83F USB RS485 Converter
These informations are provided “AS IS” and without any warranty of any kind.
This module provides an 1 Channel USB to RS485 Converter.
It is very convenient to use, and works quite well despite being based on a fake FT232RL chip. Seems to run reliable up to 115200 bps.
That being said, those modules communicate well with various RS485 and Modbus RTU based devices like power meters or solar inverters.
Pros
- PCB and components seem to be good quality, works flawlessly
- USB Type B Socket, Plug-in Screw Terminals and its compact board design make it a perfect choice for DIN Rail mounting
- Decent price-performance ratio
Cons
- FAKE FT232RL chip (Serial A50285BI)
