Great value, minor pin labeling issue
The hardware quality is solid and the STC32G performs well for industrial logic tasks. One pin label on the silkscreen was slightly faded, but the schematic cleared it up immediately. Highly recommended for evaluation.

Fast shipping and great performance
Arrived quickly and well-packaged. The STC32G12K128 is a powerful upgrade from older 8051 variants I've used. The experimental board layout gives enough space for adding temporary sensors during debugging.

Good board, needs external programmer cable
The board itself is fantastic, but remember you need a compatible USB-TTL programmer as it isn't included. Once connected, the download speed is impressive. The 128KB flash is plenty for complex state machines.

Excellent learning tool
Bought this for my embedded systems course. The Tulong Dao III.2 layout is very logical, making it easy to trace circuits. The dual CAN support allowed me to complete my final project without needing extra shields.

Robust for industrial testing
We use these for preliminary testing of automotive control logic. The voltage selection jumper is convenient, and the board has held up well in our lab environment over several months of continuous use.

Perfect for CAN bus projects
This board made setting up dual CAN channels incredibly easy. The DIP64 adapter is a nice touch for prototyping with the raw chip later. Documentation was clear and compilation worked on the first try.
Q: Does this board come with the USB downloader cable included?
A: No, the package includes only the development board and the DIP64 adapter. You will need to use a standard 5V USB-to-TTL serial adapter for programming and power.
Q: Can both CAN groups operate simultaneously at different baud rates?
A: Yes, the STC32G12K128 supports independent configuration for both CAN controllers, allowing them to run at different baud rates simultaneously.
Q: Is this compatible with Keil C51 compiler?
A: Yes, the STC32G series is fully compatible with the Keil C51 compiler. You may need to update the device database file to recognize the specific 32G12K128 model.
Q: Is the source code for the demo programs available?
A: Yes, you can download the demo source code, datasheets, and tools from the official STC MCU website or the link provided in the product manual.
Q: What is the maximum input voltage for the VIN pin?
A: When the jumper is set to 5V mode, the recommended input range is 5V ±5%. Please do not exceed 6V to avoid damaging the onboard regulator or the MCU.
