USB To UART (TTL) Mini Communication Module (With a Pre-Soldered Header)

This USB to UART (TTL) module makes it easy to connect a computer or other USB devices to TTL logic-level devices like microcontrollers and sensors, providing consistent data communication. With the original FT232RNL chip, this module offers fast, and reliable communication with excellent compatibility. Its castellated hole design and compact size provide easy integration into your projects through soldering. With a UART communication baud rate ranging from 300bps to 3Mbps, this module can adapt to various projects, and it also includes a self-recovery fuse and ESD diode, providing over-current and over-voltage protection for stable and safe operation. The TXD and RXD indicators help monitor the transceiver status, making this module a reliable and user-friendly choice for your data communication requirements. Features

* Original FT232RNL chip, fast communication, stable and reliable, better compatibility

* Castellated holes design, compact size, easy to integrate into the device by soldering

* UART communication baud rate: 300bps~3Mbps

* Self-recovery fuse and ESD diode, provide over-current/over-voltage protection, stable and safe operation

* TXD and RXD indicators for monitoring transceiver status

* Reserved VCC switching pads on the back, using 3.3V TTL by default, allow switching to 5V by re-soldering

* Adapting all function pins of the chip, more convenient for secondary development and integration

* USB Type-C port, easy plug & pull, solid and reliable

* Compatible With Systems Like Win7/8/8.1/10/11, MacOS, Linux and Android
