Perfect for learning 8051 architecture

This board is exactly what I needed to get started with the STC8 series. The pinout is clearly labeled, and it works flawlessly with the STC-ISP software. Great value for the price.

Good quality, minor soldering needed

The core board itself is high quality. Note that you may need to solder header pins yourself depending on your setup. Once connected, programming was quick and easy.

Excellent for university projects

Used this for my embedded systems final project. The 33MHz speed is plenty for basic control tasks, and the low power consumption is a bonus. Highly recommended for students.

Great starter board

Documentation could be slightly better, but there are plenty of community resources available. The board boots up instantly and is very stable during operation.

Reliable and compact

Very compact design fits well into small prototypes. I've tested the UART and PWM functions extensively without any issues. A solid choice for industrial control prototyping.

A: No, the board typically comes without header pins soldered to allow for flexible mounting options. You will need to solder them separately if required for your breadboard or project.

Q: What programmer do I need to flash code onto this board?

A: You can use any standard USB-to-TTL serial adapter (like CH340 or CP2102) along with the official STC-ISP software to flash code via the UART interface.

Q: Can this board operate at 3.3V logic levels?

A: Yes, the board supports a wide voltage range from 3.3V to 5.5V, making it safe to interface with both 3.3V and 5V peripheral modules.

Q: Is there an onboard LED for testing?

A: Yes, there is a built-in LED connected to one of the GPIO pins, which is perfect for running your first 'Hello World' blink test immediately after programming.

Q: Is this compatible with Keil C51 compiler?

A: Yes, the STC8H1K08 is fully compatible with the Keil C51 compiler. You can also use the free SDCC compiler if you prefer open-source tools.
