Teensy vs. OpenCM - Which Microcontroller is the Best for Robotics?
When it comes to choosing a microcontroller for your robotics project, there are many options available in the market. Two popular choices are Teensy and OpenCM. Both of these microcontrollers have their unique features and advantages. In this blog post, we will compare both microcontrollers to help you decide which one is the best fit for your project.
Teensy
Teensy is a series of USB-based microcontrollers designed for small and lightweight projects. The Teensy board is known for its compact size and low power consumption, making it an ideal choice for battery-powered robots. It is also highly programmable with a wide range of libraries available to make coding tasks easier. Moreover, Teensy has its own integrated development environment (IDE) that supports many programming languages such as C, C++, and Arduino.
Specs
- Processor: ARM Cortex-M4 running at 72 MHz

Comparison
When it comes to choosing between Teensy and OpenCM, there is no one-size-fits-all. The decision largely depends on the specific needs and requirements of your project. Here are some factors to consider:
Power consumption
If you are working on a battery-powered robot, then Teensy would be a better choice, as it has low power consumption compared to OpenCM.
Processing power
OpenCM has a more powerful processor and more memory, making it an ideal choice for complex robotics projects that require high processing capabilities.
Number of GPIO pins
If you need more GPIO pins for your project, then OpenCM has an advantage, as it has more digital IO pins than Teensy.
Price
Teensy is generally cheaper than OpenCM boards, making it a budget-friendly choice for hobbyists and beginners.
Conclusion
In conclusion, both Teensy and OpenCM are excellent microcontrollers for robotics projects, and the choice depends on your specific requirements. Teensy is a better choice for small, low-power projects, while OpenCM is more suited for advanced and complex projects that require high processing power and robustness.
