The Pico series are compact microcontroller boards based on Raspberry Pi-designed chips. Unlike other models, they do not run Linux or support removable storage, and are instead programmed by flashing binaries to onboard flash memory.
* The '''Raspberry Pi Pico''' (2021) was the first board based on the in-house [[RP2040]] microcontroller. It features a dual-core 32-bit ARM Cortex-M0+ CPU, 264 KB of RAM, and 2 MB of flash memory, priced at US$4.<ref>{{cite news |last1=Campbell |first1=Ian |title=The Raspberry Pi Pico is a tiny $4 microcontroller running off the company's very own chip |url=https://www.theverge.com/circuitbreaker/2021/1/21/22242619/raspberry-pi-pico-microcontroller-tiny-computer-diy-projects |access-date=22 January 2021 |publisher=The Verge |date=21 January 2021}}</ref><ref name="Adams 2021" /> The '''Pico W''' (2022) adds Wi-Fi and Bluetooth and launched at US$6.<ref>{{Cite news|url=https://www.raspberrypi.com/news/raspberry-pi-pico-w-your-6-iot-platform/|title=Raspberry Pi Pico W: your $6 IoT platform|work=Raspberry Pi|access-date=30 June 2022}}</ref> The board has a [[Via (electronics)|castellated]] edge for direct soldering to a carrier board; versions are available with pre-soldered, bottom-mounted header pins, the '''Pico H''' for US$5 and the '''Pico WH''' for US$7.
