21+ Arduino Pinout Pictures
21+ Arduino Pinout Pictures. Let the numbering begin with the rx pin (d0). So, rx is pin 1, tx is pin 2, d2 is pin 3 and so on.
It is an atmega32u4 based microcontroller board. Arduino mega 2560 pin diagram The esp32 has two i2c channels and any pin can be set as sda or scl.

With the help of the internet archive. Because the mega is the biggest arduino microcontroller, this beast has the highest number of pins and is therefore suitable for large projects where a lot of devices have to be connected to the microcontroller. In this post, we'll go over the capabilities of the arduino uno pinout. This diagram is now superceeded by the excellent and highly detailed due pinouts diagram by graynomad.
