Therefore theexternal pull up resistor R1 on the module is changed to be not mounted.3. 变更描述/ Description of Change1. 模组 ESP32-S3-WROOM-2 BOM 版本由 V0.6 变更为 V0.7；SMT BOM version of ESP32-S3-WROOM-2 is upgraded to V0.7.2. 模组 ESP32-S3-WROOM-2 上 R1（10KΩ）变更为 NC；R1（10KΩ）is not mounted on the module ESP32-S3-WROOM-2。4.变更对比/ Change ComparisonItemBefore ChangeAfter ChangeBOM versionV0.6V0.7R110 KΩNC5. 变更影响/ Impact of Change1) 品质和性能/ Quality & Performance: 无影响/ No Impact2) 交期/ Delivery: 无影响/ No Impact www.espressif.com Page2/33)生产料号/ Material Part Numbers (MPN):无影响/ No Impact4)认证/ Certification:无影响/ No Impact5)其他/ Others: NA6. 变更前后产品处理/ How to Deal with ProductsFIFO7. 相关报告/ Related Report(s):Related ECN No.ECN-2022-0268.给使用者的验证建议/ Verification Suggestion To Users变更后ESP32-S3-WROOM-2 IO45默认输出电平由1变为0，请您综合评估软硬件状态是否需进行调整。如您无法判断变更影响，可以联络乐鑫客户支持团队获得帮助。The default output of IO45 will be changed from 1 to 0. It is recommended that you check your hardware andsoftware for further assessment.
