CH341A Overview
The DataSheet of CH341 (the first) 1 USB bus convert chip CH341 English DataSheet Version:2D http://wch.cn http://wch-ic. Introduction CH341 is a USB bus convert chip, providing UART, printer port, parallel and synchronous serial with 2-wire or 4-wire through USB bus. In UART mode, CH341 provides alternant rate control signals such as serial transfer enable, serial receive in ready etc.
