USB to TTL module based on PL2303HX chip

Overview

The USB to TTL module mainly uses the PL2303HX chip, 28-pin SOIC package, working frequency of 12MHZ, in line with USB 2.0 communication protocol, can directly convert USB signals into serial port signals, baud rate from 75 to 1228800, there are 22 baud rates to choose from, and supports 5, 6, 7, 8, 16 data bits. This module has been tested in many complex environments to verify its stable performance. All schematics and PCB source files as well as BOM tables and PL2303 drivers are open source first, which is convenient for industrial control and single-chip microcomputer enthusiasts to DIY.
