Okay for basics
Documentation could be better. Had to search online for drivers.

Solid build quality
PCB is thick and pins are well soldered. Recommended for STC89C52.

Good value
Works well but USB cable not included. Had to buy separately.

Great for learning
Perfect board for my university project. Socket holds chips tightly.
Q: Does this support STC89C52RC?
A: Yes, it is compatible with most 40-pin 51 series chips.
Q: What software should I use?
A: Keil C51 or STC-ISP software works perfectly with this board.
Q: Is the USB downloader included?
A: No, this is the core board only. You need a separate USB to TTL module.
Q: Are the pin headers pre-soldered?
A: No, they are included in the package for you to solder yourself.
Q: Can I power it via USB?
A: Yes, if you have the USB interface board attached, otherwise use 5V pin.
