+## 重磅推出硬件网关
+
+受益于.netcore**跨平台**能力，此项目并**不限于**下面推荐的硬件设备，你可以在任何主机上运行，但是会针对特定硬件设备做**优化适配**，如
+
+\- **性能监控**：cpu、内存、磁盘等主机指标监控
+
+\- **硬件交互**：模拟量采集、继电器控制等
+
+### 为何推荐
+
+如果你购买了硬件网关：
+
+- **间接为开源项目做贡献**，收益的一部分会投入到开源项目建设中去，包括但不限于云服务器资源租赁、先上线向下活动等
+- 可以**免费使用**后续"企业版网关项目(筹)"
+- 可以**免费使用**网络透传等服务
+- 提供详细的**教程文档**，包括**Linux系统**、**dotnet跨平台等**
+- 可用于**学习、评估、和生产环境**使用
+
+### 产品列表
+
+- 下列型号均有"**蓝牙BLE 5.0**、**Wi-Fi**"
+- 搭载**Linux**操作系统```debian.11```
+- 时间关系，目前只整理了 [A080](http://iotgateway.net/docs/hardware/A080/introduction) 型号的资料，其他用法差不多，后续会更新
+- 9月后会推出**24v**版本
