 ## Onboard Resources
 
-The Blue Pill is a STM32F103 based development board with Cortex-M3 ARM CPU that runs at 72 MHz, 20 KB of RAM and 64 or 128 KB of flash memory. The microcontroller (MCU) has a USB port, two serial ports, 16 bit PWM pins and 12 bit ADC pins. It runs at 3.3V, but some of its pins are 5V tolerant.

 ### Running Results
 
 After the program is successfully downloaded, the system runs automatically. Observe the running results of the LED on the development board, and you will see the LED is flashing periodically.

 ## **Advanced Features**
 
-This BSP only enables GPIO and USART1 by default. If you need more advanced features such as SPI, ADC, or to add software packages, you need to configure the BSP with RT-Thread [ENV tools](https://www.rt-thread.io/download.html?download=Env), as follows:
