Industrial USB to RS485 Converter

This is an industrial USB to RS485 converter from Waveshare with an original FT232RL chip. The USB to RS485 converter is very easy to use, allowing for automated sending and receiving of data via RS485. With this RS485 adapter, you can, for example, control Arduino's from a PC that are connected via RS485. Installation is very simple, first install the drivers for the FT232R and then you can select the serial USB port and send data to the RS485 via a serial console.

Features

USB to RS485 communication
Original FT232RL
Onboard TVS (Transient Voltage Suppressor) for protection against voltage spikes
Self-resetting fuse and protection diodes
3 LEDs to display operating states such as sending, receiving and operating voltage
