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]
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] The Raspberry Pi 3 Model B was released in February 2016 with a 1.2 GHz 64-bit quad core ARM Cortex-A53 processor, on-board 802.11n Wi-Fi, Bluetooth and USB boot capabilities. [23]
GPIOs usually employ standard logic levels and cannot supply significant current to output loads. When followed by an appropriate high-current output buffer (or mechanical or solid-state relay), a GPIO may be used to control high-power devices such as lights, solenoids, heaters, and motors (e.g., fans and blowers). Similarly, an input buffer ...
The microcontroller is low cost, with the Raspberry Pi Pico 2 being introduced at US$5 and the RP2350 itself costing as little as US$0.80 in bulk. The microcontroller is software-compatible with the RP2040 and can be programmed in assembly , C , C++ , Free Pascal , Rust , MicroPython , CircuitPython , and other languages.
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).
Many of these systems interface with consumer electronics such as the Arduino or Raspberry Pi, which are easily accessible online and in most electronics stores. [23] In addition, home automation devices are increasingly interfaced with mobile phones through Bluetooth, allowing for increased affordability and customizability for the user. [8]
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.
RP2040 is a 32-bit dual ARM Cortex-M0+ microcontroller integrated circuit [1] [2] [3] by Raspberry Pi Ltd. In January 2021, it was released as part of the Raspberry Pi Pico board. [ 1 ] Its successor is the RP2350 series.
