I have a esp32 devkit1. I'm using the GPIO 4 (BIT4 in my program) to control something that expects 3.3V. The devkit1 is just powered by USB. It seems the output is quite low sometimes, like 2.7V. Are all GPIOs outputting the same voltage? Is my board defective or is this usu...
Would it be preferrable to power the INA260 with the 3.3V output pin of the ESP32 versus connecting both devices to the 5V output of the L7805CV? Does using the ESP32's 3.3V internal voltage regulator place unnecessary stress on the ESP32? Pro/cons of each method?

是否是通用Output voltage settling time这个参数计算的?还是通过规格书中的其他指标查看,谢谢。 答:DAC82002的采样率确实是1Msps。这个参数可以在DAC82002的数据手册中找到。关于Output voltage settling time,这个参数是指DAC输出电压稳定到一定范围内所需的时间,与采样率没有直接关系。采样率主要关注的是DAC在单位...
