Arduino Uno compatible board powered by ATmega2560. D0/D1 can be changed to D19/D18. It enables to multiple serial communication. [132] A4/A5 are not connected to SDA/SCL same as Arduino Mega. Mega 2560 PRO (Embed) ATmega2560-16AU RobotDyn: Embed version of Mega 2560 CH340G/ATmega2560 - compatible with Arduino Mega 2560 board.

Some devices are transmit-only; others are receive-only. Chip selects are sometimes active-high rather than active-low. Some devices send the least-significant bit first. Signal levels depend entirely on the chips involved. And while the baseline SPI protocol has no command codes, every device may define its own protocol of command codes.
Finally, a rising edge of SCL (while SDA is high) completes the restart sequence. Targets then listen for a new address and command at the current (high) data rate. AN HDR exit consists of four (or more) falling edges of SDA, while SCL is held low. Finally, a rising edge of SCL (while SDA is held low), completes the HDR exit sequence.
The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2010. [2] [3] The microcontroller board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. [1]
