My device not configured an external circuit for GPIO0 (I have confirmed that it has an internal pull-up resistor). In this case, would adding an external pull-up resistor to GPIO0 be helpful? Thanks.username Posts: 552 Joined: Thu May 03, 2018 1:18 pm Re...

The pull-up value of a USB pin is controlled by the pin’s pull-up value together with USB pull-up value. If any of the two pull-up values is 1, the pin’s pull-up resistor will be enabled. The pull-up resistors of USB pins are controlled by USB_SERIAL_JTAG_DP_PULLUP bit. ...

My circuit consists of just the module with a pull up resistor on GPIO8 and another one one the enable pin. I'm not sure about the "N4" suffix but here is the exact module I used https://www.robotics.org.za/ESP32-C3-WR ... esp32%20c36...
I'm using a DFRobot ESP32-C3 and want to monitor it's battery voltage using ADC1 GPIO 2. The circuit for connecting up GPIO2 is a voltage divider and a capacitor. I've verified the resistor values with a multimeter and tested for continuity. ...
