Universal USB Converter for USB-UART, USB-I2C, USB-I3C

Overview

Description

The rise of IoT and embedded systems has increased the demand for flexible and universal connectivity solutions, where connecting different hardware components to a PC for testing, programming, and debugging is crucial. The ability to connect various devices through a single USB interface simplifies workflows and enhances productivity, especially in environments requiring frequent hardware testing and configuration.

This universal USB converter allows users to connect any Universal Asynchronous Receiver Transmitter (UART), Serial Peripheral Interface (SPI), Inter-Integrated Circuit (I2C), and even the latest Improved Inter-Integrated Circuit (I3C) devices via flexible cables to a PC using a terminal program or dedicated software. This reduces the complexity of hardware interfacing, making it easier for developers to connect, control, and visualize their hardware setups. The converter can also be easily adapted with Pmod™ boards, including Renesas QuickConnect IoT boards.

System Benefits:

  • Universal connection of any hardware via USB-UART, USB-SPI, USB-I2C, or USB-I3C with a flexible cable connection provides versatility in connecting to a wide range of devices.
  • Compatibility with various Pmod boards, including Renesas QuickConnect IoT boards, facilitates faster prototyping and development.
  • Control and visualization via a standard terminal program on the PC side (or dedicated PC software) enhances user experience.
  • Semi-automatic switching between Pmod Type 2A (SPI), Type 3A (UART), and Type 6A (I2C) increases efficiency by reducing manual configuration time.
  • Integrated regulator down to 3.3V with low noise provides stable power to connected devices, improving the reliability and performance of the hardware during testing and operation.
