Good board, driver installation tricky

The hardware quality is solid. I had some trouble finding the right CH340 driver initially, but once installed, uploading code was smooth.

Works but pins are tight

The board functions as described. However, the IC socket was a bit tight for my DIP chips. Had to be careful inserting the MCU.

Perfect for learning 51 MCU

This board is exactly what I needed to start learning embedded systems. The CH340 driver worked fine on Windows 10. Highly recommended for students.

Reliable for projects

I've used this for several hobby projects. The pins are labeled clearly, and the reset button is very responsive. Great value.

Great value for money

Can't beat the price for a functional 8051 development board. It comes with the USB cable which was a nice surprise.
