Our Review
After integrating the Teensy 2.0 USB AVR Development Board Accelerate Embedded USB Board into several test builds, we found it to be a capable component for the price. Key specs include Processor: ARM Cortex-M7 600MHz, Flash: 256KB, RAM: 64KB.
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 USB Board 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
- Arduino IDE and PlatformIO compatibility
- OTA update capability for remote firmware deployment
- Low power sleep modes for battery-powered applications
- Extensive community support and online tutorials
Watch Out For
- 3.3V logic only — needs level shifting for 5V peripherals
- Deep sleep wake sources are restricted on some GPIO pins
- Limited SRAM constrains complex data structures
