The Raspberry Pi 4 is the 4th generation of the mainline series of Raspberry Pi single-board computers.Developed by Raspberry Pi (Trading) Ltd [1] and released on 24 June 2019, the Pi 4 came with many improvements over its predecessor; the SoC was upgraded to the Broadcom BCM2711, two of the Raspberry Pi's four USB ports were upgraded to USB 3.0, and options were added for RAM capacities ...
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 I 2 C interfaces, or can be used as a stand-alone Arduino when powered with the external power header. Romeo 2012 [98] DFRobot [99] ATmega328 16 MHz
Announced on 21 January 2021, the RP2040 is the first microcontroller designed by Raspberry Pi Ltd. [1] [2] The microcontroller is low cost, with the Raspberry Pi Pico being introduced at US$4 and the RP2040 itself costing US$1.
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.
2 November 2020 – Raspberry Pi 400 launched. It is a keyboard which incorporates Raspberry Pi 4 into it. GPIO pins of the Raspberry Pi 4 are accessible. [395] 21 January 2021 – Raspberry Pi Pico launched. It is the first microcontroller-class product from Raspberry Pi. It is based on RP2040 Microcontroller developed by Raspberry Pi. [47]
The Raspberry Pi (Model 2B shown) is a low-cost single-board computer often used to teach computer science. [1]A single-board computer (SBC) is a complete computer built on a single circuit board, with microprocessor(s), memory, input/output (I/O) and other features required of a functional computer.
RAM access tested using the mbw benchmark is 25% faster than the Raspberry Pi 3. SD card (microSD) access is about twice as fast at 37 MiB/s for buffered reads (compared to typically around 18 MiB/s for the Pi 3 [ 30 ] ) due to the Tinker Board's SDIO 3.0 interface, while cached reads can reach speeds up to 770 MiB/s.
The ARM Cortex-A53 processor has been used in the LeMaker HiKey since 2015, [3] the Raspberry Pi 3 since February 2016, [4] and the Raspberry Pi Zero 2 W since October 2021. [ 5 ] The Cortex-A53 is also used in a number of Qualcomm , Samsung , and MediaTek SoCs .
