Re: what ESP32D0WDQ6 is 160Mhz

Hi Yanite123,

Did you perhaps try to do something with the fuses? Any chance you can run the 'dump' and/or 'summary' command of espefuse.py and post the results here? Thanks.

Re: 关于使用esp32模块的产品提交FCC认证

Hi Jiangteng,

1. https://www.espressif.com/zh-hans/suppo ... ther-tools 参考《射频性能测试指南》
2. 如果您的产品是 IC on-board 设计,是需要单独过 FCC 认证;如果使用乐鑫已认证模组,是可以直接使用乐鑫认证证书的。

谢谢。
