I confirmed that all the pins do not conflict with any C3 core functions (but a second set of eyes is probably a good idea). I am going off of the Version 1.1 C3 datasheet from Espressif - which does seem to have a few conflicts in the pin table. Cross posted from arduino forum....
which should be “Hence, we can not use UART1 directly without reassigning pins in Arduino IDE.” Reply tom December 7, 2022 at 3:35 pm Hi in Digital input Only section you have mentioned six pins that are input only however there are only 4 as per the pinout image. PIN 37,38 is...
On the Arduino you can pin map like so Code: Select all pinMode(A0, OUTPUT); digitalWrite(A0, HIGH); Since there are so many analog input pins, it would be good to convert it to a digital pin. I've tried this but it doesn't work for the ESP32. Is this still in the works ...

When using the ESP32 with the Arduino IDE, you should use the ESP32 I2C default pins (supported by the Wire library): GPIO 21 (SDA) GPIO 22 (SCL) SPI By default, the pin mapping for SPI is: Interrupts All GPIOs can be configured as interrupts. ...
然后就是这里面的一块核心开发板,这块板是arduino的升级版,能兼容arduino,相当于是个多了几个功能的arduino plus,它的名字叫ZYDUINO。 还有附带的两条连接线,一条是usb数据线,用来供电/下载;另一条是带电池扣的DC电源供电线。 上面是第一包零件包

step to install ESP32 library in Arduino IDE ESP32 Pin mapping ESP32 GPIO pins with LED blinking example ESP32 push button interfacing Now make this circuit diagram on your bread board and after that, we will write a code to measure voltage using a variable resistor. ...
Conversely, if you want to use the digital function, then you should use the letter "D" as the prefix for the pin number, such as D4, D5. After uploading the program, open the Serial Monitor in Arduino IDE and set the baud rate to 9600. Wait for the oxygen sensor to warm up, ...
