Waveshare 23949, FT232RL and SP485EEN, USB to RS485/422 Isolated Converter

Characteristics:
1. Original FT232RL and SP485EEN chip on board; fast, stable and reliable communication speed, better compatibility
2. Built-in power isolation on board, providing stable isolation voltage, no additional power supply is needed at the isolation end
3. Built-in on-board digital isolation, signal isolation, high reliability, strong anti-interference, low power consumption
4. Built-in TVS (transient voltage suppressor), effectively suppresses overvoltage and transient peak voltage in the circuit, lightning protection and anti-static
5. Built-in automatic recovery fuse and protection diode to ensure stable current/voltage output, provide over-current/over-voltage protection and improve shock resistance
6. Built-in 15KV ESD isolation protection and 600W lightning surge protection
7. The RS485/RS422 interface has an onboard 120R terminating resistor, which is enabled by default and can be configured via jumpers
8. 3 LEDs to indicate power and transceiver status
9. Industrial grade railway type ABS shell design, small size, easy installation, high cost performance
