Wave Industrial USB TO 4CH UART TTL Converter

The Wave Industrial USB TO 4CH UART TTL Converter extends USB to 4CH TTL (UART) with hardware flow control, which allows concurrent and independent communication for each channel. The module has an onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs and provides over-current/over-voltage proof, improves shock resistance. The module has onboard IO protection circuit for surge suppress and ESD protection, allowing safe and stable communication. The onboard TTL serial port 3.3V and 5V voltage level switch, allows selecting TTL level.
