DSD TECH SH-U05A USB to SPI IIC I2C UART 3-in-1 Adapter Review

As an avid electronics enthusiast, I am always on the lookout for new and reliable communication connection devices. Over the years, I have tested various adapters and modules, with mixed results. Recently, I came across the DSD TECH SH-U05A USB to SPI IIC I2C UART 3-in-1 Adapter, and decided to give it a try. In this review, I will share my experience with this product and provide an honest opinion for potential buyers.

Design:

The DSD TECH SH-U05A adapter comes in a compact and sturdy plastic casing, measuring 45mm x 20mm x 12mm. The product is lightweight and easy to carry, making it ideal for fieldwork or prototyping. The adapter has three interface connectors, including USB to TTL UART, USB to SPI, and USB to I2C. The adapter also has a switch to adjust the I2C clock speed, with four options, ranging from 20KHz to 750KHz.

Setup:

To test the adapter, I connected it to my Windows 10 PC using a USB cable. The adapter was immediately recognized by the operating system without requiring any additional drivers. I then connected the adapter to a couple of I2C EEPROMs, including the AT24C01, using the provided female-to-female DuPont jumpers. I used a terminal emulator program to send and receive commands from the adapter, which worked flawlessly.

Testing:

Next, I tested the SPI interface by connecting the adapter to a WINBOND W25Q40BV SPI memory chip. The adapter had a fixed baud rate of 2Mbps, which was not adjustable. I used the same terminal emulator program to read and write data to the chip, which also worked well.

Lastly, I tested the UART interface by connecting the adapter to an Arduino board. I set the baud rate to 9600bps and tested the serial communication by sending and receiving data between the adapter and the arduino board. The communication was stable and reliable.

Overall, the DSD TECH SH-U05A adapter performed well in all three modes of operation, and I was satisfied with its performance.

Pros:

- Compact and sturdy design

- Easy to use and compatible with Windows 10

- Supports I2C, SPI, and UART interfaces

- Four I2C clock speeds to choose from

Cons:

- Fixed baud rate for SPI interface

- Limited documentation and support

- Lower star rating from other customers (2.8 out of 5 stars)

Conclusion:

In conclusion, the DSD TECH SH-U05A USB to SPI IIC I2C UART 3-in-1 Adapter is a versatile and reliable communication adapter that can be a valuable tool for electronics enthusiasts and professionals. Its compact and sturdy design, along with its ease of use and multiple interface support, make it an excellent choice for fieldwork or prototyping. The only downside is the fixed baud rate for SPI communication and the limited documentation and support. However, I found the product to be highly compatible and functional, and I would recommend it to others who are looking for a reliable communication adapter.
