    Fully Arduino compatible board, that fits perfectly on a Raspberry Pi, and can be programmed through the Raspberry Pi's serial interface. It also breaks out the Raspberry Pi's SPI and I²C interfaces, or can be used as a stand-alone Arduino when powered with the external power header. Romeo 2012 [108] ATmega328 DFRobot [109]

    The Raspberry Pi 2 B was released in February 2015 and initially featured a 900 MHz 32-bit quad-core ARM Cortex-A7 processor with 1 GB RAM. Revision 1.2 features a 900 MHz 64-bit quad-core ARM Cortex-A53 processor (the same as that in the Raspberry Pi 3 Model B, but underclocked to 900 MHz). [22]

    en.wikipedia.org/wiki/General-purpose_input/output

    Some boards, which are classified usually as multi-function I/O boards, are a combination of both; such boards provide GPIOs along with other types of general-purpose I/O. GPIOs are also found on embedded controller boards and Single board computers such as Arduino, BeagleBone, and Raspberry Pi. [3]

    en.wikipedia.org/wiki/Arduino

    Arduino (/ ɑː r ˈ d w iː n oʊ /) is an Italian open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices.

  8. Serial Peripheral Interface - Wikipedia

    en.wikipedia.org/wiki/Serial_Peripheral_Interface

    Typical applications include interfacing microcontrollers with peripheral chips for Secure Digital cards, liquid crystal displays, analog-to-digital and digital-to-analog converters, flash and EEPROM memory, and various communication chips. Although SPI is a synchronous serial interface, [2] it is different from Synchronous Serial Interface (SSI).

  9. I²C - Wikipedia

    en.wikipedia.org/wiki/I²C

    I 2 C is popular for interfacing peripheral circuits to prototyping systems, such as the Arduino and Raspberry Pi. I 2 C does not employ a standardized connector, however, board designers have created various wiring schemes for I 2 C interconnections. To minimize the possible damage due to plugging 0.1-inch headers in backwards, some developers ...
