Introduction

Teensy microcontrollers have gained popularity among hobbyists and professionals alike for their powerful performance and compact size. The Teensy 4.0 and Teensy 4.1 are two of the latest offerings from PJRC, each with its own set of features and capabilities. In this article, we will compare the attributes of Teensy 4.0 and Teensy 4.1 to help you decide which one is best suited for your project.

Processor

One of the key differences between Teensy 4.0 and Teensy 4.1 lies in their processors. Teensy 4.0 is powered by a 600 MHz ARM Cortex-M7 processor, while Teensy 4.1 boasts a faster 600 MHz ARM Cortex-M7 processor with a floating-point unit. This means that Teensy 4.1 is better equipped to handle complex mathematical calculations and real-time processing tasks compared to Teensy 4.0.

Memory

When it comes to memory, Teensy 4.0 and Teensy 4.1 also differ in their capacities. Teensy 4.0 features 2 MB of Flash memory and 1 MB of RAM, while Teensy 4.1 offers a larger 8 MB of Flash memory and 512 KB of RAM. This means that Teensy 4.1 can store more program code and data in memory, making it suitable for applications that require a higher memory capacity.

Connectivity

Both Teensy 4.0 and Teensy 4.1 come equipped with a variety of connectivity options, including USB, I2C, SPI, and UART interfaces. However, Teensy 4.1 also features an additional Ethernet port, which allows for network connectivity and communication. This makes Teensy 4.1 a better choice for projects that require internet connectivity or communication with other devices over a network.

Form Factor

In terms of form factor, Teensy 4.0 and Teensy 4.1 are nearly identical, with both boards measuring 2.4 x 0.7 inches. This compact size makes them ideal for projects where space is limited, such as wearable devices or small robots. Additionally, both boards feature a microSD card slot for additional storage and expansion capabilities.

Price

Price is another factor to consider when choosing between Teensy 4.0 and Teensy 4.1. Teensy 4.0 is generally more affordable than Teensy 4.1, making it a budget-friendly option for hobbyists and students. On the other hand, Teensy 4.1 offers more advanced features and capabilities, which may justify the higher price tag for professional projects or applications that require higher performance.

Conclusion

In conclusion, Teensy 4.0 and Teensy 4.1 are both powerful microcontrollers with their own strengths and weaknesses. Teensy 4.0 is a cost-effective option with decent performance and memory capacity, while Teensy 4.1 offers faster processing speeds, more memory, and additional connectivity options. Ultimately, the choice between Teensy 4.0 and Teensy 4.1 will depend on your specific project requirements and budget constraints.
