Raspberry Pi Pico Developer Board overview
Raspberry Pi Pico is a low-cost, high-performance microcontroller board with flexible digital interfaces, built on silicon designed at Raspberry Pi. It is a single-sided PCB measuring just 21mm x 51.3mm with a micro-USB port and 40 main user pins with through-hole pins to allow for surface mounting. The Raspberry Pi Pico is a flexible and cost-efficient development platform that has been fully designed, based on their very own RP2040 chip.
The Raspberry Pi Pico has been designed to be used either soldered 0.1" pin-headers (it is one 0.1" pitch wider than a standard 40-pin DIP package), or can as a surface mountable '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 in case the board is used as a reflow soldered SMT module.
