The Raspberry Pi Pico is the first product built on silicon designed by Raspberry Pi. At its heart is RP2040, a Raspberry Pi-designed chip, which features Dual Core ARM Cortex-M0+ clocked at 133MHz; 256KB RAM; 30 GPIO pins; and a broad range of interfacing options. Raspberry Pi Pico is paired with 2MB of onboard QSPI Flash memory for code and data storage.

The Pico can be quickly and easily programmed using MicroPython and C/C++ using popular editors such as Thonny.

The main chip on board is a dual-core ARM Cortex M0+ processor the 'RP2040' made by Raspberry Pi.
