This page says
“If the power of the RS485 device is small and the required current is less than 12V-160mA, the RS485 to UART signal conversion module does not require a 12V external power supply, making wiring more convenient.”
Does that mean the

Does that mean the UART signal conversion module does not require a 12V external power supply or the PAR module does not? Or is the 12v in necessary?
Thanks
