SP3220 USB RS232 TTL UART Cable

This cable provides a USB to serial bridge using the SP3220 chipset for RS232 to TTL UART conversion. It suits developers, engineers and hobbyists who need a direct wired link between a modern USB host and legacy serial equipment or microcontroller boards. The four-pin wire-end termination supplies TXD, RXD, GND and VCC connections for flexible integration into custom projects.

6FT cable length for sustained data transfer

The six-foot cable length gives enough reach for bench testing or permanent installation without signal degradation during extended sessions. Continuous operation relies on the SP3220 bridge maintaining stable voltage levels across the TXD and RXD lines while the host supplies power through the VCC pin. Users who require galvanic isolation or higher baud-rate headroom beyond the chipset's specification should consider alternative solutions.

Questions about this item

How much heat does the SP3220 chip generate during continuous use?

The SP3220 USB-to-UART bridge draws little current, so it stays cool during all-day operation.

What connector must my target device provide for the four flying leads?

The cable ends in bare wires for TXD, RXD, GND and VCC that you solder or plug into a matching 4-pin header.
