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 board

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
  • Flash Memory: 512 KB
  • RAM: 64 KB
  • Input Voltage: 3.6-5.5V
  • Digital IO Pins: 34

OpenCM

OpenCM board

OpenCM is a microcontroller designed by Robotis for robotics and automation projects. It features powerful processing capabilities and supports various sensors, actuators, and communication protocols, making it an excellent choice for complex and advanced projects. One of the most significant advantages of OpenCM is its robustness and reliability, allowing it to perform under extreme conditions. It also has a comprehensive software package that includes libraries and sample codes for faster development.

Specs

  • Processor: ARM Cortex-M3 running at 72 MHz
  • Flash Memory: 2 MB
  • RAM: 128 KB
  • Input Voltage: 7-30V
  • Digital IO Pins: 50

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.
