I put the GPIO as ground so that only during a portion of time I will set it to low and measure the voltage at the other GPIO. Otherwise, I want little to no current flow. This is the situation that worries me as during this effectively the battery voltage is directly given to the GPIO (as only 1 ...

I want to know the Voltage tolerance of ESP32 C3 Mini 1 pins. I am planning to make a charge sensing circuit. In order to do that, I am attaching the pin of esp32 c3 mini 1 to battery (3.7V Li ion battery which max voltage can be around 4.1V) by a 100k resistor. Would this damage the pin and MCU. IS ...

yeah there were 2 pullups which were unnecessary. it is now solved thank you

I am using ESP32C3 mini 1 chip for my custom PCB and using 2 sensors LIS2DH12R and MMC5603NJ , with the combination of these three in the low power mode(deep sleep for mcu stand by for magnetometer and lower power mode for accelrometer.) I was ezpecting a current consumption around 20uA consideing i ...
