· Product Introduction

The SPC1031-KB is a practical USB-to-serial port module. Its core function is to bridge the gap between a computer's USB interface and a physical serial port, enabling data conversion between the two and facilitating communication between different devices.

The module features three built-in level conversion chips, enabling flexible conversion between USB and RS232, RS485, and TTL levels. Compatible with Windows, Linux, and Mac OS, it connects easily and is convenient to use. Its flame-retardant plastic housing enhances safety during use.

The module's internal circuitry is meticulously designed, with optimized impedance matching in key signal paths to minimize signal attenuation during high-speed data transmission. The module also features a built-in 200mA auto-recovery fuse, which automatically disconnects when current exceeds 200mA, protecting both your device and the USB port.
