CH340E USB to TTL

The CH340E USB to TTL is a converter module used to transform a USB interface into a serial TTL signal. It features the CH340E chip, known for its compact design and stable communication performance, making it ideal for embedded development, microcontroller programming, and debugging. The module supports multiple baud rates and is compatible with both 3.3V and 5V operating voltages, making it suitable for various development platforms, such as Arduino and Raspberry Pi.

Key features of the CH340E module include built-in USB driver support for multiple operating systems (including Windows, Linux, and Mac OS) and no need for an external crystal oscillator, which simplifies circuit design. Additionally, the module provides standard serial pins (TXD, RXD, GND, VCC) for easy connection and debugging. Its small size makes it perfect for space-constrained applications.

Product Features
