ESP32模组芯片

Postby linyaqiang » Wed Dec 05, 2018 2:28 am

请问乐鑫的芯片ESP32-D0WDQ6里面的管脚:SENSOR_VP、SENSOR_CAPP、SENSOR_CAPN、SENSOR_VN,这四个管脚能否配置成普通输入IO来使用呢?因为我看到datasheet上面的SENSOR_VP与SENSOR_CAPP,SENSOR_CAPN与SENSOR_VN上面都互相串上一个270pF电容,请问能否把电容去掉直接引出IO当作输入使用?

SENSOR_VP、SENSOR_CAPP、SENSOR_CAPN、SENSOR_VN只能作为输入管脚来用;并联的270nF电容可以去掉。
