16+ Arduino Mega Pinout Sda Scl Pictures. Arduino mega voltage regulators maximum current for i/o pins because the mega is the biggest arduino microcontroller, this beast has the highest number of. It is used to synchronize the shift of data between the two devices.
SHT25@I2C will nicht from electronics.trev.id.au Support twi communication using the wire library. Two pins 20 and 21 support i2c communication where 20 represents sda (serial data line mainly used for holding the data) and 21 represents scl(serial clock line mainly. These may not be labeled due the the icsp header for the atmega16u2 not leaving any room on the silkscreen there.
Complete arduino mega pinout diagram and circuit information and specifications.
And so many other related questions, like what is the memory difference? The arduino mega 2560 is a replacement of the old arduino mega, and so in general reference, it will digital pin 20 for sda and 21 for sck (speed 400khz) to enable. On any relatively new mega board, there are also dedicated sda and scl pins at the end of the female header nearest the usb jack.
