Esp32 Can I Use 26 Gpio Pins General Electronics Arduino Forum Can i use 26 pins on esp wroom 32 digital output: 9 pins digital input: 3 pins analog input: 4 pins analog output: 2 pins scl sda: 2 pins tx rx: 6 pins "which pins cannot be used,(how much in total) and which ones are incorrect? for instance, i've read that gpio 36 and gpio 39 are connected to internal sensors and should not be used. additionally, gpio 34 and gpio 35 can only be utilized as. The figure below illustrates the esp wroom 32 pinout. you can use it as a reference if you’re using an esp32 bare chip to build a custom board: note: not all gpios are accessible in all development boards, but each specific gpio works in the same way regardless of the development board you’re using.
Esp32 Can I Use 26 Gpio Pins General Electronics Arduino Forum The pins are multi function. for example, d0 d3 can be used as general purpose io as well as analog to digital channels, so you have to prioritize the usage. if you need 2 channels of adc then you have to devote 2 of those 4 pins to the task. likewise, if you need i2c for an lcd screen, you can't use d4 or d5 as gpio. i make a spreadsheet in google docs to map out my pins so i can easily move. Overview the arduino nano esp32 is a nano form factor board based on an esp32 s3 soc. this board is part of the arduino nano family, and follows the same pinout as all nano boards. this is very convenient if you want to port a project from another nano board, as you can preserve the same wiring and pin numbers in the code. this means that if you want to control a pin you can simply use the pin. Good morning. could you help me identify which gpio pins will serve as pull up inputs? i want to use three pushbuttons without external resistors, so i need to know which pins are suitable for this. i have searched a lot in the documentations and via google, other platforms and i have found absolutely nothing related to the topic. Gpio 6 to gpio 11 are exposed in some esp32 development boards. however, these pins are connected to the integrated spi flash on the esp wroom 32 chip and are not recommended for other uses.

I have 3 spi sensors of which i am trying to read with an esp32 (datasheet) using the following configuration: i am using the vspi interface of the module in the datasheet, which lists the cs pin as gpio5. but in this case i will need 3 cs pins. so how do i select the other 2 cs pins?. Are there specific pins to be used as a can bus on esp32? peripherals like adc, i2c and others need to use specific pins. does this happen with can too? i'm using the following configuration: 2 esp32 devboard boards arduino on platformio pin 5 as tx and pin 4 as rx (already in the can library), 2 sn65hvd230 transceiver modules.
