Rpi 1B+

The Model B+ is the final revision of the original Raspberry Pi. It replaced the Model B in July 2014 and was superseded by the Raspberry Pi 2 Model B

Compared to the Model B it has:

  • More GPIO pins. The GPIO header has grown to 40 pins, while retaining the same pinout for the first 26 pins as the Model A and B.
  • More USB ports. It comes with 4 USB 2.0 ports, compared to 2 on the Model B, and better hotplug and overcurrent behaviour.

Compared to the Model A it has:

  • More GPIO pins. The GPIO header has grown to 40 pins, while retaining the same pinout for the first 26 pins as the Model A and B.
  • Micro SD. The old friction-fit SD card socket has been replaced with a much nicer push-push micro SD version.
  • Lower power consumption. By replacing linear regulators with switching ones we've reduced power consumption by between 0.5W and 1W.
  • Better audio. The audio circuit incorporates a dedicated low-noise power supply.
  • Smaller neater form factor. We've aligned the USB connector with the board edge, moved composite video onto the 3.5mm jack, and added four squarely-placed mounting holes. Model A+ is approximately 2cm shorter than the Model A.

Compute Module

Rpi CM3+

The Compute Module 3+ (CM3+) is a Raspberry Pi 3 Model B+ in a flexible form factor, intended for industrial applications

The CM3+ Compute Module contains the guts of a Raspberry Pi 3 Model B+ (the BCM2837 processor and 1GB RAM) as well as an optional eMMC Flash device of 8GB, 16GB or 32GB (which is the equivalent of the SD card in the Pi).

  • Broadcom BCM2837B0, Cortex-A53 (ARMv8) 64-bit SoC @ 1.2GHz
  • 1GB LPDDR2 SDRAM
  • 8GB/16GB/32GB eMMC Flash memory, or a Lite variant without eMMC Flash memory

This is all integrated onto a small (67.6mm × 31mm) board that fits into a standard DDR2 SODIMM connector. The Flash memory is connected directly to the processor on the board, but the remaining processor interfaces are available to the user via the connector pins. You get the full flexibility of the BCM2837 SoC (which means that many more GPIOs and interfaces are available than with a standard Raspberry Pi), and designing the Module into a custom system should be relatively straightforward because we've put all the tricky bits onto the Module itself.

To help you get started designing a PCB to use the Module, we provide an open-source breakout board, which is supplied with both a 32GB and Lite version of the CM3+ in an affordable development kit.

Rpi CM3 IOBoard

Raspberry Pi Pico Series

The Raspberry Pi Pico series is a family of microcontroller boards developed by the Raspberry Pi Foundation. Unlike the full-size Raspberry Pi computers, which are capable of running Linux-based operating systems, the Pico boards are designed for embedded systems and bare-metal programming. They are ideal for low-power, real-time applications such as robotics, IoT devices, and sensor networks.

More information about using the Raspberry Pi Pico series.

Overview

The Pico boards are based on the RP2040 or RP2350 microcontrollers—both custom chips designed by the Raspberry Pi Foundation. These boards are highly affordable, compact, and versatile, making them a popular choice among hobbyists, educators, and professionals.

Compared to other Raspberry Pi models (such as the Pi 4 or Pi Zero), the Pico boards do not support Linux or other conventional operating systems. Instead, they are typically programmed using C/C++ or MicroPython, and they interface directly with hardware through GPIO, SPI, I²C, UART, ADCs, and PWM outputs.

Variants

Several variants of the Raspberry Pi Pico exist, including:

  • Pico – Base model with no Wi-Fi and no pre-soldered headers.
  • Pico H – Includes pre-soldered headers.
  • Pico W – Includes onboard Wi-Fi (IEEE 802.11n) for wireless communication.
  • Pico WH – Includes both onboard Wi-Fi and pre-soldered headers.

These variants allow users to choose the configuration that best fits their project needs—whether for compact integration, breadboard prototyping, or wireless networking.
