From Coding Toy to Industrial Backbone
Chances are, you’ve heard about Raspberry Pi.
Maybe you used one in a school project. Maybe your kid did. Perhaps you've seen it featured in Maker videos on YouTube. What started in 2012 as a $35 educational computer to teach kids programming has now grown into something far bigger.
However, most people are unaware that Raspberry Pi has quietly transformed into one of the most versatile and potent platforms for developing comprehensive Internet of Things (IoT) solutions.
Yes, the same tiny board you once used to play retro games now powers factory monitoring systems, smart greenhouses, environmental data loggers, and commercial-grade IoT gateways. It’s inside rugged enclosures in warehouses. It’s mounted in classrooms with 42” displays. It’s helping engineers monitor laser cutters in Idaho and water systems in California government buildings.
So how did we get here?
A Quick Backstory
A very specific problem—kids were no longer learning how computers worked—led to the creation of Raspberry Pi. The Raspberry Pi Foundation, a UK-based nonprofit, set out to build an affordable, hackable device to bring computing education back to life.
The bet worked — big time.
Over 50 million Raspberry Pi boards have been sold as of early 2025. But along the way, something unexpected happened: engineers, tinkerers, and even enterprise professionals started using them to solve real problems.
They're inexpensive.
They're versatile.
And they’ve built up one of the most passionate ecosystems in tech.
Now, thanks to a wide range of compute modules, microcontrollers, carrier boards, and industrial SBCs, Raspberry Pi isn't just an educational tool. It’s a complete IoT hardware platform— with a Pi for every part of the IoT stack.
Understanding the IoT Stack—Turning the Physical World into Smart Data
So what does “end-to-end IoT” really mean?
At its core, an IoT system turns the physical world into digital data—and then turns that data into decisions, insights, or actions. That journey happens across three critical layers:
1. Device Layer: Smart Sensors, Actuators & Microcontrollers
This is where the real world meets digital logic.
Sensors detect physical inputs — temperature, motion, vibration, light, humidity, CO₂, etc.
Actuators create physical responses — turn on a fan, close a valve, or adjust lighting.
Microcontrollers gather the data from sensors, process it locally, and transmit it over a network.
This layer is the “sense + talk” part of IoT.
Common Examples:
Soil moisture sensors in farms
CO₂ sensors in classrooms
Vibration sensors on manufacturing equipment
2. Network Layer: IoT Gateways
Gateways collect sensor data and route it to where it needs to go — the cloud, a local server, or an edge computer.
They act as protocol translators and mini-data centers, handling:
Aggregation of data from multiple devices
Protocol bridging (Modbus, Zigbee, LoRa, MQTT, etc.)
Data filtering and pre-processing
Secure network communication
This layer is the “connect + control” brain.
3. Edge Compute Layer: Local Analytics, AI & Automation
Here’s where raw data becomes meaningful.
Edge compute devices analyze sensor data close to the source, reducing the need for cloud dependency. They:
Detect patterns and trigger alarms
Run machine learning models
Visualize data dashboards
Automate responses in milliseconds
Think of this level as the “think + act” layer.
Why it Matters: An effective IoT platform isn’t just about one part of the chain. It’s about mastering the whole flow, from sensing the world to responding in real time — all while keeping data ownership, flexibility, and cost in check.
That’s where Raspberry Pi shines.
How Raspberry Pi Powers Every Layer of the IoT Stack
1. Smart Sensor Layer — Raspberry Pi RP2350 & Pico 2 W
When you need to turn a simple sensor into a smart, wireless, connected device, Raspberry Pi Pico 2 W is your go-to board.
Powered by the RP2350 chip, this microcontroller brings serious upgrades:
Dual-core Cortex-M33 @ 150 MHz—2× the performance of RP2040
Wi-Fi (802.11n) + Bluetooth 5.2
4 MB onboard flash, 512 KB SRAM
Native support for MicroPython, C/C++, CircuitPython
With built-in wireless, it’s easy to collect sensor data and send it over MQTT, HTTP, or TCP — no shield or hat needed.
Real-World Use Case: Connect a temperature sensor to Pico 2 W and have it report data every 10 seconds to a local dashboard running Machinechat JEDI over Wi-Fi. Done in under 15 minutes. No cloud. No server. No headaches.
Machinechat JEDI Pairing
Use the HTTP API or MQTT collector on JEDI to receive data from Raspberry Pi Pico 2 W.
Display it instantly on a live dashboard.
Set up rules: If temp > 85°F, send an alert or turn on a fan.
2. IoT Gateway Layer — Raspberry Pi 5, CM4, and CM5
The gateway layer is where Raspberry Pi’s versatility really shines.
Raspberry Pi 5 as a DIY Gateway
Quad-core Cortex-A76 @ 2.4GHz
Gigabit Ethernet + USB 3.0
PCIe support and dual 4K HDMI
Runs full Linux (Raspberry Pi OS, Ubuntu, or OpenWRT)
Want to build a smart building hub, edge router, or field data gateway?
Just flash OpenWRT on a Pi 5 and install JEDI. Connect the protocol module or an RS485 interface, and you’ve now got a gateway that supports LoRa, Zigbee, Modbus, MQTT, Ethernet, and USB sensors — all in one box.
Compute Module 4 (CM4) and Compute Module 5 (CM5)
These modules put the power of Raspberry Pi into embedded products:
Real-World Gateways Built on CM4:
OnLogic Factor 201—Raspberry Pi Industrial IoT Gateway
Seeed reRouter—Raspberry Pi CM4-based Mini Router
Elastel EG410—Raspberry Pi CM4-based Industrial IoT Gateway
CM5 is now appearing in newer industrial edge gateways, unlocking faster data transfer, AI inferencing, and PCIe expansion.

Collect data from Modbus sensors, serial interfaces, or wireless devices
Use JEDI's built-in rules engine to filter, alert, and automate actions — no cloud, no code
3. Edge Compute Layer — Raspberry Pi 5, CM5, and Industrial SBCs
Edge computing is about turning raw data into local decisions. Fast.
Raspberry Pi 5
Handles local AI models (Edge Impulse, TensorFlow Lite)
Edge data processing (Node-RED, Python scripts)
Use it for object detection, anomaly detection, or localized trend analysis
CM5 in Industrial SBCs
These systems bring the Raspberry Pi’s brain to rugged, always-on deployments — from factory floors and smart buildings to farm silos.
