The Raspberry Pi family is like a sprawling tree with many branches — each designed for different adventures in computing. Here’s a quick stroll through its history and how the Pico fits in:

  • Raspberry Pi 1 (2012): The OG SBC that sparked a revolution in affordable computing. Single-core ARM11, 256MB RAM, no Wi-Fi.
  • Pi 2 & Pi 3 Series: Added multi-core CPUs, Wi-Fi, Bluetooth, and more RAM, making them versatile for education and hobbyist projects.
  • Pi 4 (2019): The powerhouse with a quad-core Cortex-A72, up to 8GB RAM, USB 3.0, and Gigabit Ethernet. A desktop replacement for many.
  • Pi Zero (2015): The tiny, stripped-down sibling, perfect for ultra-compact projects.
  • Raspberry Pi Pico (2021): The microcontroller cousin, built on the RP2040 chip designed in-house by Raspberry Pi Foundation. Unlike other Pis, it’s not a computer but a microcontroller board — think Arduino with a Pi twist!

Why Pi™ engineers love the Pico because it’s a game-changer for embedded systems — low cost, low power, and easy to program in C/C++ or MicroPython.

🛠️ Hardware Showdown: Raspberry Pi Pico vs Raspberry Pi 4 and Others

Let’s get our hands dirty with the nitty-gritty hardware details. We’ll break down the key differences that separate the Pico from its bigger siblings.

1. CPU and Performance Differences

Board CPU Type Cores Clock Speed Architecture Performance Use Case
Raspberry Pi Pico ARM Cortex-M0+ 2 133 MHz Microcontroller (MCU) Real-time control, low-power tasks
Raspberry Pi 4 Broadcom BCM2711 Cortex-A72 4 1.5 GHz Single-board computer Desktop OS, multimedia, networking
Raspberry Pi Zero W Broadcom BCM2835 ARM11 1 1 GHz Single-board computer Lightweight Linux applications

Why does this matter?
The Pico’s Cortex-M0+ is a microcontroller core — it’s designed for real-time, deterministic tasks like sensor reading, motor control, or simple automation. It’s not meant for running Linux or multitasking heavy apps. The Pi 4’s Cortex-A72 is a powerful CPU designed for multitasking, running full OSes, and handling complex software.

2. Memory and Storage Options

Board RAM Storage Type Storage Size
Raspberry Pi Pico 264 KB SRAM 2 MB onboard QSPI Flash Fixed, no expansion
Raspberry Pi 4 2GB / 4GB / 8GB LPDDR4 MicroSD card slot User-selectable (up to 1TB+)
Raspberry Pi Zero W 512 MB LPDDR2 MicroSD card slot User-selectable

Insight:
The Pico’s RAM is tiny compared to the Pi 4 or Zero — it’s not meant to run large programs or store files. Instead, it stores firmware and runs embedded code directly from flash. The Pi 4’s RAM and expandable storage make it a full computer.

3. Connectivity and Ports

Feature Raspberry Pi Pico Raspberry Pi 4 Raspberry Pi Zero W
Wi-Fi ❌ None ✅ Dual-band 2.4/5 GHz ✅ 2.4 GHz
Ethernet ❌ None ✅ Gigabit ❌ None
Bluetooth ❌ None ✅ Bluetooth 5.0 ✅ Bluetooth 4.1
USB Ports 1x USB 1.1 (device mode) 2x USB 3.0, 2x USB 2.0 1x USB OTG
GPIO Pins 26 pins 40 pins 40 pins

The Pico is minimalist — no networking built-in, just GPIO pins for sensors and actuators. The Pi 4 and Zero come with full networking stacks and multiple USB ports for peripherals.

4. Power Consumption and Efficiency

Board Typical Power Draw Power Source
Raspberry Pi Pico ~100 mW 1.8V to 5V via USB or GPIO
Raspberry Pi 4 3-7 W 5V USB-C power supply
Raspberry Pi Zero W ~0.5-1 W 5V micro USB

Why Pi™ engineers love the Pico: It’s a battery-friendly champion for IoT devices that need to run for months or years on small batteries.
