Introduction
PJRC’s Teensy 4.1 and the Net Burner SOMRT1061 are both great products. The Teensy tends to be used by hobbyists, and the SOMRT1061 for large scale production. The goal of this article is to compare the two products and show that the SOMRT1061 is an excellent choice for any project or product, whether it be hobbyist or a company product that must meet rigorous industrial requirements. NetBurner development kits aren’t just developer and product-friendly – they’re product-minded and include things like life-cycle support, industrial temperate range, and end-user tools, for deployment, configuration and application updates.
Teensy 4.1, developed by PJRC and widely used by makers and educators. It comes in a 40-pin DIP package to enable a low-barrier for experimentation. The NetBurner SOMRT1061 is available in two form factors: an 88-pin 1-inch (25.4mm) square soldered-down SOM, and an 88-pin SOM-on-carrier with standard 0.1 inch (2.54mm) male headers for easy troubleshooting, development, and prototyping.
- Deployable by Design: Surface-mount form factor, –40°C to +85°C industrial temperature ranges, ready to be pick-n-place’d or added to an existing product.
- Alternate Package with Easy toAccess 0.1” Header Pins: For anyone that prefers standard header pins instead of a solder down SOM.
- Built-In Memory Muscle: 32MB External is RAM included and part of the application and data space (as opposed to external memory). No soldering or reconfiguration necessary.
- Industrial-Grade Networking: Dual Ethernet ports, onboard PHY, and IEEE 1588 support out of the box.
- Continuity That Scales: ISO 9001, RoHS, revision control, lifecycle transparency, and sourcing reliability that go beyond the bench: we’re here to support your product’s success for years to come, not throw you curveballs.
- Protocols That Just Work: Native stacks for MQTT, Modbus, and TCP/IP ensure clean implementation and secure communication.
Whether you’re validating a concept or preparing for full-scale rollout, NetBurner supports your engineering goals with reliability, sourcing, and developer-first support so you can prototype without second-guessing your path to production.
In the sections ahead we’ll break down how NetBurner and Teensy stack up, from hardware specs and connectivity to deployment readiness and developer experience.
From Dev Kit to Deployment: Designing for the Finish Line
Not all microcontroller platforms are created equal. NetBurner’s SOMRT1061 isn’t just a microcontroller on a dev board—it’s a production-grade ARM M7 system-on-module engineered to smooth the gaps between prototyping, development, deployment, and assembly-line production.
You can start with NetBurner and stay with NetBurner. When you get a SOMRT1061 development kit, you start with a SOM surface-mount soldered to a carrier board, which is plugged into the development board using common 0.1” header pins. You can flash your app to it over the network within seconds and breadboard your proof of concept immediately, and then quickly start flashing low-quantity prototypes and beta units by getting additional SOMRT1061s on carrier boards and swapping them out. When you’re ready to condense your design, simply delete the headers from the outside of the footprint and shrink the PCB layout to use surface-mount SOMRT1061s instead, once again flashable over the network after assembly. Finally, factories can use pick-n-place machines and your own flashing/testing procedures to solder, program, and validate your high-volume product. Or, if you never reach high volume, the SOMRT1061 is still quite hand solderable!
Whether you’re prototyping a one-off scientific instrument or scaling up for a regulated deployment, NetBurner’s whole product line minimizes hardware rework, finicky bring-up procedures, and future headaches.
Use Case Comparison: NetBurner SOMRT1061 vs PJRC Teensy 4.1
There’s definitely overlap between these microcontrollers in embedded systems and edge computing, but the key difference usually hinges on scale, reliability, and/or deployment environment. Let’s break this down:

Making the Leap: From Versatility to Viability
There’s real overlap between NetBurner and PJRC’s Teensy especially when it comes to prototyping workflows and flexible embedded applications. But when projects move from concepts or production, context starts to matter more than convenience.
If your build is destined for home automation, maker demos, or short-run MVPs, Teensy’s affordability and Arduino-style ecosystem offer strong appeal. But when your system faces industrial conditions, requires sustained sourcing, or demands professional-grade networking, Teensy’s strengths may begin to bend under pressure.
That’s when teams pivot to NetBurner.
Whether it’s needing built-in RAM for audio or video frames, onboard Ethernet for automation, temperature tolerance beyond 70°C, or long-term lifecycle transparency, NetBurner meets the moment. Its surface-mount design, deployment-grade SDKs, and industrial documentation make it ideal for integration not just experimentation.
And for developers coming from Teensy, transitioning isn’t daunting. Most embedded libraries are cross-compatible, and NetBurner’s dedicated tools, IDEs, and support resources are tailored to keep momentum moving without rework.
The move from hobby-grade to deployment-ready microcontrollers isn’t just about capability—it’s about choosing a platform that reduces risk, respects your roadmap, and builds with intention.
Beyond the Bench: Why Some Hobbyists Start and Finish with NetBurner
Not every embedded journey begins with industrial ambitions. For hobbyists and DIY engineers, platforms like PJRC’s Teensy deliver tremendous flexibility and low barrier to entry, especially for consumer-grade automation and lightweight sensor projects.
But NetBurner isn’t reserved for enterprise deployment. In fact, many users discover it after hitting walls in their existing products or hobby builds, often when networking becomes critical. That’s where NetBurner shines: its SOMs are designed to drop into larger systems, with native Ethernet, dual PHY support, and module-based integration that saves time and headaches.
Teensy’s pricing and Arduino-based ecosystem make it a great starting point for casual hobbyists. But for projects that demand industrial features like PoE, remote management, or stable long-term sourcing NetBurner often becomes the better fit. Its SOMs plug easily into custom systems, offer native networking capabilities, and are backed by solid documentation and direct technical support. If you’re comfortable designing your own boards or building something that might outgrow weekend status, NetBurner gives you the tools to scale without compromise.
It’s not just about scale. It’s about intention. When your “hobby” starts looking like a future product, NetBurner offers a path with fewer compromises.
When Your Hobby Project Turns Into a Product
For those weighing the move, it helps to understand the key limitations that tend to surface when Teensy moves beyond the bench. Here’s where small-scale strengths start to stretch and where NetBurner’s engineering-grade platform proves its staying power.
Teensy boards are brilliant for early prototyping and DIY innovation, but when it’s time to build a product that ships in the thousands or operates within a critical industrial process, limitations begin to surface:
- Memory Expansion Is Optional, Not Native: While Teensy 4.1 includes 1MB of internal RAM and 8MB of Flash, that’s it. Developers can manually solder up to two PSRAM chips to expand RAM up to 16MB, but this isn’t standard and requires extra setup. In contrast, NetBurner offers 32MB of External RAM onboard—ready from the start and ideal for applications that demand high memory throughput.
- Limited long-term sourcing: Hobbyist boards like Teensy may change form factors or components without guaranteeing long-term availability, which can disrupt supply chains for production.
- Packaging not optimized for mass deployment: DIP-style packaging suits breadboarding but complicates surface-mount manufacturing. Aligning single-row headers adds time, effort, and cost.
Less industrial compliance and ruggedization: NetBurner’s temperature range and signal interface protection suit regulated, industrial environments where Teensy can fall short.
