Technical overview

Based on the RP2040 microcontroller chip designed by Raspberry Pi, featuring a dual-core Arm Cortex M0+ processor with a flexible clock running up to 133 MHz.
Built-in 264 KB SRAM and onboard Flash memory available in 4 MB or 16 MB variants.
The castellated module form factor allows direct soldering onto carrier boards.
Supports USB 1.1 hosts and slave devices; drag-and-drop programming via USB mass storage is possible.
Includes multiple hardware peripherals: 2× SPI, 2× I2C, 2× UART, 3× 12-bit ADCs, 16 PWM channels, an on-chip temperature sensor, and 8× PIO state machines for custom peripheral support.
Compatible with most Raspberry Pi Pico modules while adding or enhancing features.

Notes and version constraints

The path settings mentioned in the wiki (CMake, Git, Ninja, Python) refer to a Windows environment and are version-sensitive; paths must be adapted to the local system before use.
Flashing MicroPython firmware on RP2040 boards may differ from the Pico: press and hold both BOOT and RESET buttons, release RESET first then BOOT so that a removable disk appears.
The official MicroPython firmware was originally limited to 2 MB of memory; the corresponding 4M or 16M firmware must be used for those variants.
The VSCode extension requires at least VS Code v1.87.0; older installations need updating.
When doing C/C++ development, the CMake file must not contain Chinese characters, otherwise project import may fail.
