+
+![board](figures/board.jpg)
+
+该开发板常用 **板载资源** 如下：
+
+- MCU：STM32G070RB，主频 64MHz，128KB FLASH ，36KB RAM
+- 外部 RAM：无
+- 外部 FLASH：无
+- 常用外设
+  - 按键：1个，user（兼具唤醒功能，PC13）
+- 常用接口：USB 转串口、arduino 接口等
+- 调试接口，标准 SWD
+
+开发板更多详细信息请参考 ST 的 [NUCLEO 开发板介绍](https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mcu-eval-tools/stm32-mcu-eval-tools/stm32-mcu-nucleo/nucleo-g070rb.html)。
+
+## 外设支持
+
+本 BSP 目前对外设的支持情况如下：
+
+| **板载外设**      | **支持情况** |           **备注**                |
+| :----------------- | :----------: | :------------------------------------- |
+| ST-LINK 虚拟串口 |     支持     |          使用 USART2               |
+| **片上外设**  | **支持情况** |               **备注**                 |
+| GPIO         |     支持     | PA0, PA1... PC15 ---> PIN: 0, 1...47  |
+| UART         |     支持     |             USART1/2/3                |
+| TIM          |     支持     |               TIM1/3                  |
+| PWM          |     支持     |                                       |
+| SPI          |     支持     |               SPI1/2                  |

+| ADC          |     支持     |                                       |
+| WDT          |     支持     |                                       |
+| FLASH | 支持 | 已适配 [FAL](https://github.com/RT-Thread-packages/fal) |
+| RTC          |   暂不支持    |           详见注意事项                   |
+
+## 使用说明
+
+使用说明分为如下两个章节：
+
+- 快速上手
+
+    本章节是为刚接触 RT-Thread 的新手准备的使用说明，遵循简单的步骤即可将 RT-Thread 操作系统运行在该开发板上，看到实验效果 。
+
+- 进阶使用
+
+    本章节是为需要在 RT-Thread 操作系统上使用更多开发板资源的开发者准备的。通过使用 ENV 工具对 BSP 进行配置，可以开启更多板载资源，实现更多高级功能。
+
+### 快速上手
+
+本 BSP 为开发者提供 MDK5 和 IAR 工程，并且支持 GCC 开发环境。下面以 MDK5 开发环境为例，介绍如何将系统运行起来。
+
+#### 硬件连接
+
+使用数据线连接开发板到 PC，打开电源开关。
+
+#### 编译下载
+
+双击 project.uvprojx 文件，打开 MDK5 工程，编译并下载程序到开发板。
+
+> 将工程使用的仿真器设置为ST-Link并安装仿真器好驱动程序以后，将开发板连接到PC，点击下载按钮即可下载程序到开发板。
+
+#### 运行结果
+
+下载程序成功之后，系统会自动运行。
+
+连接开发板对应串口到 PC , 在终端工具里打开相应的串口（115200-8-1-N），复位设备后，可以看到 RT-Thread 的输出信息:
+
+```bash
+ \ | /
+- RT -     Thread Operating System
+ / | \     4.0.2 build Jul  1 2020
+ 2006 - 2019 Copyright by rt-thread team
+msh >
+```
+
+### 进阶使用
+
+此 BSP 默认只开启了 GPIO 和 UART 的功能，如果需使用 SPI，I2C 等更多高级功能，需要利用 ENV 工具对BSP 进行配置，步骤如下：
+
+1. 在 bsp 下打开 env 工具。
+
+2. 输入`menuconfig`命令配置工程，配置好之后保存退出。
+
+3. 输入`pkgs --update`命令更新软件包。
+
+4. 输入`scons --target=mdk5/iar` 命令重新生成工程。
+
+本章节更多详细的介绍请参考 [STM32 系列 BSP 外设驱动使用教程](../docs/STM32系列BSP外设驱动使用教程.md)。
+
+## 注意事项
+
+- G0系列RTC驱动有点问题，详见论坛 [该贴](https://www.rt-thread.org/qa/thread-424601-1-2.html)
