Our Review
After integrating the Teensy 2.0 USB AVR Development Board Accelerate Embedded and Testing into several test builds, we found it to be a capable component for the price. Key specs include Processor: ARM Cortex-M4 72MHz, Flash: 32KB, RAM: 1MB.
Development experience was smooth. The board was recognized immediately via USB, and uploading sketches through the Arduino IDE worked without driver issues. PlatformIO users will also find ready-made board definitions.
The GPIO pinout is well-designed with clear silkscreen labeling. We tested I2C, SPI, and UART peripherals without bus conflicts. PWM output was clean on the oscilloscope with minimal jitter.
Overall, the Teensy 2.0 USB AVR Development Board Accelerate Embedded and Testing fills its role well. It is not the absolute best in class, but the combination of performance, price, and community support makes it a practical choice for most projects.
What We Like
- Low power sleep modes for battery-powered applications
- Built-in USB for easy programming without external programmer
- Flash storage sufficient for complex applications
- Extensive community support and online tutorials
Watch Out For
- Deep sleep wake sources are restricted on some GPIO pins
- USB-to-serial chip may require driver installation on some OS versions
- Pin labels on the board are tiny and hard to read
