Perfect for university projects

This board matches the specifications used in our Jiangke University video tutorials exactly. It was plug-and-play with the STC-ISP software. Great value for students learning 8051 architecture.

Solid basic board

Works well for basic GPIO and timer experiments. The crystal oscillator is stable. I deducted one star because the silk screen printing is a bit faint, but functionally it is flawless.

Fast shipping and works great

Arrived quickly and was well packaged. The board boots up immediately and the onboard LED blinks as expected with the default firmware. Ready for custom coding right out of the box.

Excellent compatibility

I needed a replacement for my old Lu Xiaoban kit, and this is identical. The code from my previous projects uploaded without any modifications. Highly recommended for DIY kits.

Good for classroom sets

Bought ten of these for my introductory electronics class. They are consistent and reliable. The only minor issue is that the USB cable included is quite short, but that's easily replaced.

5 FAQ

Q: Can I power this board via the USB port alone?

A: Yes, the board is designed to be powered directly through the mini-USB or micro-USB port (depending on the specific batch) connected to a computer or a 5V USB adapter.

Q: What software do I need to upload code?

A: You will need the STC-ISP software, which is available for free download from the manufacturer's website. It supports Windows and allows easy hex file uploading.

Q: Is this compatible with Keil C51 compiler?

A: Absolutely. This board uses the standard 8051 architecture and is fully compatible with the Keil C51 compiler, as well as SDCC and other popular 8051 development environments.

Q: Does this board come with a pre-installed bootloader?

A: Yes, the STC89C52 chip comes with the standard ISP bootloader pre-installed, allowing you to program it directly via the USB interface without an external programmer.

Q: Are the pinouts labeled clearly on the board?

A: Yes, all GPIO ports (P0, P1, P2, P3) and power pins are clearly labeled with silk screening on the PCB to assist with wiring and debugging.
