<br />
== Technical overview ==<br />
* Core processor: Dual-Core Arm Cortex-M0+ (RP2040), clock up to 133 MHz<br />
* Memory: 264 KB SRAM and 2 MB onboard flash memory<br />
* Interfaces: 2× SPI, 2× I²C, 2× UART, 4× 12-bit ADC, 16 PWM channels, 8 PIO state machines<br />
* Connector: FPC 8-pin socket; USB Type-C provided via a separate adapter board<br />
* Form factor: Castellated module for direct soldering onto carrier boards; thin, compact design<br />
* USB 1.1 with device and host support; drag-and-drop programming via mass storage<br />
* 20 multi-function GPIO pins plus on-chip temperature sensor and precise clock/timer<br />
* Development environments: Thonny for MicroPython, VS Code with Pico extension for C/C++, Arduino IDE with Arduino-Pico board support<br />
<br />
== Notes and version constraints ==<br />
* Version-specific: The FPC connector was updated from V1.1 onward; identify version by the "Rev*. *" marking on the back<br />
* Do not unplug while powered – risk of short circuit when removing the cable<br />
* Flashing firmware: Hold BOOT button, connect board, then copy the firmware file to the appearing drive<br />
* VS Code: CMake files must not contain Chinese characters, otherwise project import may fail<br />
* Pico2 firmware from the Micropython package can cause recognition issues; use the recommended firmware files<br />
