UBYTE-Quad Channel USB to UART Converter with ESP32 Programmer

The Quad Channel USB-to-UART Converter is a versatile and high-performance

interface designed for applications requiring multiple UART connections over a

USB interface. It integrates the USB-to-Quad UART bridge, providing four

independent serial channels with adjustable voltage levels (1.8V, 3.3V, and 5V).

Key Features:

● USB Type-C Interface – Provides power and high-speed data

communication.

● Quad UART Bridge – Converts USB data into four UART channels, ensuring

efficient serial communication.

● Voltage Level Shifters – Supports multiple logic levels for broad device

compatibility.

● ESP32 Boot and Reset Buttons – Dedicated programmable Channel B with

boot/reset controls for ESP32 development.

● Multiple Power Domains – Includes LDO regulators for 5V, 3.3V, and 1.8V

operation.

● LED Indicators – Status LEDs for power, UART activity, and ESP32 boot/reset

functions.

● Modular Voltage Selection – Allows independent voltage control for each

channel.

Applications:

● Embedded System Development

● ESP32 Firmware Programming

● Industrial Automation

● IoT and Smart Device Prototyping

● Multi-UART Debugging & Monitoring

This converter offers robust electrical protection, modular design, and a reliable

USB-to-serial communication solution for developers and industrial users alike.
