Chapter 2. Mechanical Specification
The Raspberry Pi Pico is a single sided 51x21mm 1mm thick PCB with a micro-USB port overhanging the top edge and
dual castellated/through-hole pins around the remaining edges. Pico is designed to be usable as a surface mount module
as well as being in Dual Inline Package (DIP) type format, with the 40 main user pins on a 2.54mm (0.1") pitch grid with
1mm holes and hence compatible with veroboard and breadboard. Pico also has 4x 2.1mm (+/- 0.05mm) drilled
mounting holes to provide for mechanical fixing, see Figure 3.

2.1. Raspberry Pi Pico Pinout
The Pico pinout has been designed to directly bring out as much of the RP2040 GPIO and internal circuitry function as
possible, while also providing a suitable number of ground pins to reduce EMI (Electro Magnetic Interference) and signal
crosstalk. This is important in general but especially for RP2040 which is built on a modern 40nm silicon process and
hence the digital IO edge rates are very fast.
