CW32 small blue board-lceda

CW32F030C8T6 microcontroller core board

Can replace STM32F103C8T6 core board,

This project is an open source version and is not available for commercial use. The commercial version has been launched and is priced at 9.9 yuan.

The chip manual and data sheet are at the end of the article.

characteristic:

1.USB Type-C input (6P), and designed with anti-static ESD (added a Zener diode)

2. Since the chip has a wide voltage input feature, you can choose 5V or 3.3V working state (jumper the RJ resistor)

3. The voltage stabilizing circuit uses AMS1117-3.3V. Compared with the LDO on the market that is only equipped with a load capacity of 200mA (the specific model is forgotten), the driving capability is greatly enhanced.

4. LSE crystal oscillator compatible design, plug-in or SMD 32.768K crystal oscillator can be used

5. Widen the power traces to increase overcurrent capability

6. Cancel the BOOT jumper design and add user buttons

7. BOOT0 leads out the pad window to meet special testing requirements.

8. Cheap

shortcoming:

1.CW32F030C8 chip does not support USB data transmission

Digression:

There are many core boards of this shape on Taobao. I contacted its earliest designer. This design was originally designed to be compatible with the 51 development board seat (DIP40 IC locking seat).
