Microcontrollers & SBCs

Microcontrollers are special purpose PCBs [Printed Circuit Boards], while SBCs are Single Board Computers.

Single Board Computers (SBCs)

Raspberry Pi

A family of SBCs


An opensource SBC platform that includes several models of varying capabilities


A crowd-funded, hackable SBC

Orange Pi

a collection of Raspberry Pi look-alikes at a cheaper price

OrangePi 3 LTS

Orange Pi 4 LTS

I have one of these, so updating this page as I learn more about it

OrangePi 5

Asus Tinker Board

Khadas VIM2

Microcontrollers (MCUs)

RP2040 Boards

In 2020, Raspberry Pi introduced their first custom chip, the RP2040, first used in the RPi Pico. It has become wildly popular as the basis for a number of devices.

RPi Pico & Pico W


Tiny 2040


Rather than SBCs, Arduino (and Arduino-compatible) boards are microcontrollers, suitable for robotics and other embedded applications.

Native Arduino Boards

This article compares and contrasts all 9 "native" Arduino boards.

Arduino Uno

Arduino Mega

Arduino Nano

Arduino-Compatible Boards

Since the Arduino specification is open source, many third-party makers have created compatible devices. These are a few of them.
