ESP32模组选型

请教一下各位大佬关于ESP32选型的问题。

目前用ESP32-Lyrat这个开发板做了一下语音识别,唤醒这些功能,现在想做成一个实际的PCB来测试。在ESP32-Lyrat上用的是ESP32-WROVER这个模组,根据规格书,此模组已经不适用于新产品设计了。如果采用ESP32-S3-WROOM-1-N16R8这个模组的话,以前的固件变化大吗?还仍然可能使用ESP-Skainet这个SDK吗?

谢谢

Some questions about ESP32-wroom module

hi everyone, I am ready to use ESP32-WROOM module as main chip for my product, now I have some questions for this module: 1. As this module already has FCC/CE/BQB/ROHS certification, shall I do these certification for my product again? 2. How can I measure RF in a production line when this module is...
