Raspberry Pi Pico [DEV-17829] - (AD60968)

Description:

The Raspberry Pi Pico is a low-cost, high-performance microcontroller board with flexible digital interfaces. It features the RP2040, marking Raspberry Pi's first in-house designed microcontroller. Pico provides a minimal (but flexible) external circuit to support the RP2040 chip (Flash, crystal, power supplies and decoupling, and USB connector). Most of the RP2040 microcontroller pins are brought out to the user IO pins on the left and right edges of the board. Four RP2040 IOs are used for internal functions: driving an LED, switched mode power supply (SMPS) power control, and sensing the system voltages.

Pico uses an on-board buck-boost SMPS which can generate the 3.3 volts needed (to power the RP2040 and external circuitry) from a wide range of input voltages (~1.8 to 5.5V). This allows for significant flexibility to power the unit from various sources, such as a single LiPo cell or 3 AA cells in series. Battery chargers can also be very easily integrated with the Pico power chain. Reprogramming the Pico's flash memory can be done via USB (simply drag and drop a file onto the Pico which shows up as a mass storage device) or via the Serial Wire Debug (SWD) port. The SWD port can also be used to interactively debug code execution on the RP2040.

Pico has been designed to use 0.1" soldered pin headers (it has a wider 0.1" pitch than a standard 40-pin DIP package) or can be used as a surface mount "module" as the user IO pins are also castellated. There are SMT pads underneath the USB connector and BOOTSEL button, which allow these signals to be accessed if used as a reflow soldered SMT module.
