STM32F103RCT6 mini development board

Hardware Design Features of MiniSTM32 V4 Development Board

1. Rich Interface Support
The board provides over ten types of standard interfaces, enabling convenient experimentation and development with various peripherals.

2. Flexible Design
Most onboard resources are configurable to meet different application requirements. All I/O pins (except those used by crystal oscillators) are accessible, significantly enhancing expansion capabilities. The integrated one-click download function eliminates the need for repeated B0/B1 configuration, allowing complete STM32 development through a single USB cable.

3. Sufficient Resources
Main controller: STM32F103RCT6 with 256KB internal Flash, extended with 8MB external Flash to accommodate substantial data storage requirements.

4. User-Friendly Design
- Clear silkscreen labeling with outlined boxes for intuitive interface identification
- Frequently used peripherals highlighted with prominent silkscreen markings
- Ergonomic interface layout ensuring convenient operation
- Logical resource distribution maximizing utilization efficiency
