Nah pada board Nano32, letak Capacitive Touch pin nya berbeda dengan Sparkfun ESP32 Thing, begitupun letak Groung (GND) pin, 5V, dan 3V. This example code for Arduino shows a quick way to create a temperature sensor, it simply prints to the serial port what the current temperature is in both Celsius and Fahrenheit. The maximum allowable voltages are documented in the ESP32 datasheet. Specifically, it contains two 12-bit multiplexed analog to digital converters (ADCs) for a total of 18 channels. There are tons of GPIO and analog inputs available to you for connecting LEDs, buttons, switches, sensors, etc. The on-board regulator on an Arduino can only supply a tiny amount of current (a few tens of mA) at 5V to external circuitry (beyond what the Arduino itself needs). Hence you can use this module easily with Arduino. RP2040: GPIO26 through GPIO29 can be used. Inputs Three 15V tolerant (analog) inputs IO34, SENSOR_VN/36, SENSOR_VP/39, external connected on J1 Three 5V tolerant (analog) inputs on the ADS1115, first two cann be used to measure differential. two things you need attention: The ADC maximum input voltage ≤ 2. I have connected IR LED's on both pins and reading analog signals.
