CH340E-USB-TYPE-C to TTL

Overview

Product Introduction:

The CH340E USB-TYPE-C to TTL module uses the CH340E as its core, with an internal crystal oscillator and a maximum baud rate of 2Mbps. It is software-compatible with the CH341 driver, features backflow protection, and provides corresponding communication and power interfaces. The communication interface has indicator lights to show the working status, ensuring stable communication and a compact size.

Product Features:

USB TYPE-C Interface:
Full-speed USB device interface, compatible with USB V2.0.
Fully compatible with serial port applications under Windows operating systems on the computer side, requiring no modification.
Hardware full-duplex serial port with built-in transmit/receive buffers, supporting baud rates from 50bps to 2Mbps.
Built-in firmware; software compatible with CH341, allowing direct use of the CH341 VCP driver. This is a downloadable USB-to-serial driver for Windows,
supporting TTL level 5V. It's a one-click installation driver for CH340 and CH341, compatible with 32/64-bit Windows 11/10/8.1/8/7/VISTA/XP, SERVER 2022/2019/2016/2012/2008/2003, 2000/ME/98, and is Microsoft digitally signed. It supports 3-wire and 9-wire USB-to-UART serial ports and is intended for distribution to end users with products.
