## 版本区分

LicheeRV Nano 先后生产两个版本的硬件,分别为内测版(PCB识别号:70405),量产版(70415)。两者外观和性能上存在些许差异

![](./../assets/RV_Nano/intro/CMP-70405-70415.jpg)

1. 4*0201电阻修改为0402排阻,方便焊接;
2. WiFi模组更换为有屏蔽罩的版本;
3. 增大电源处电容规格,提升电源质量;
4. 移动两颗电容到TF卡下,支撑TF卡,方便用户拔插;
5. 用丝印明确标出电阻位置,方便用户修改;
6. 标明PCB版本号。

## 注意事项

+ 内测版硬件(70405)NPU 仅支持工作在0.5T下,1.0T下运行不保证板卡运行的稳定性
+ 内测版硬件(70405)的WIFI尚未完善匹配,速率较低,敬请谅解
+ 若购买摄像头配件或WE版本套餐,包装内随附螺丝、焊接铜柱和螺丝刀,为避免焊接时烫伤,请参照[摄像头、WE网口小板安装指南](https://wiki.sipeed.com/hardware/zh/lichee/RV_Nano/2_unbox.html)
+ 若购买3寸、4寸、10.1寸屏幕配件,包装内随附屏幕转接板以及排线,请参照[屏幕安装指南](https://wiki.sipeed.com/hardware/zh/lichee/RV_Nano/2_unbox.html)

+ 内测版WiFi模块旁有两颗电容距离较近,生产时存在贴合的可能,因引脚网络相同,无需担心短路问题

## 大核作为A53模式启动

LicheeRV Nano的大核支持作为RISC-V(C906)或ARM(A53)启动,在开发板背面,SG2002芯片旁边有丝印圈出的短接电阻,如下图所示,默认贴在C906(RISC-V)一侧

![](./../assets/RV_Nano/unbox/A53-1.jpg)

若大核需要作为ARM启动,需要将该电阻挪至另外一边,如下图

为提升用户使用体验,我们开源了LicheeRV Nano + 2.28寸屏幕(即将上架) + 摄像头 的3D打印框架
