USB HID Host to TTL Converter Module

Description

USB HID Host to TTL Converter Module Product Description: This USB Host Module allows you to connect USB HID devices such as barcode scanners, keyboards, and similar peripherals directly to any microcontroller via UART.It uses the CH554 USB Host Controller IC to handle the USB protocol and automatically convert received USB data into simple serial UART output — readable by Arduino, STM32, ESP32, and other MCUs. Simply plug in your USB device, connect the TX/RX pins to your controller, and read data at 115200 baud — no complex USB driver required. Features: Supports USB HID devices (keyboard, barcode scanner, etc.) Converts USB data to UART serial output (ASCII string format) Plug-and-play operation — no firmware needed on the module Default baud rate: 115200 bps (8N1) Works with 5V logic microcontrollers (Arduino, STM32, etc.) Onboard 5V voltage regulator for stable USB device power Status LED for power indication Compact and easy to integrate into any embedded system Technical Specifications: Parameter Description Controller IC CH375B / CH392 series USB Host Controller Interface UART (TX, RX, GND, +5V) Baud Rate 115200 bps Supported Devices USB Keyboard, USB Barcode Scanner Power Supply 5V DC (regulated) USB Port Standard USB-A female connector Operating Voltage 5V Logic Level 5V UART output Dimensions ~50mm × 20mm Mounting Holes Yes (2 × M3 compatible) Output Format ASCII characters (HID decoded) Applications: Barcode scanner integration for POS systems USB keyboard data in
