The Raspberry Pi Zero v1.3 was released in May 2016, which added a camera connector. [40] The Raspberry Pi Zero W was launched in February 2017, a version of the Zero with Wi-Fi and Bluetooth capabilities, for US$10. [41] [42] The Raspberry Pi Zero WH was launched in January 2018, a version of the Zero W with pre-soldered GPIO headers. [43]

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.
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]
This configuration only requires a single CS line from the main, rather than a separate CS line for each sub. [ 7 ] In addition to using SPI-specific subs, daisy-chained SPI can include discrete shift registers for more pins of inputs (e.g. using the parallel-in serial-out 74 xx165) [ 8 ] or outputs (e.g. using the serial-in parallel-out 74 ...
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.
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.
