Our Review
For $19.69 CAD, the New Teensy 2.0 USB AVR Development Board ISP UDisk Keyboard Mouse Experimental Board AT90USB1286 Development and Testing packs respectable specs: Processor: AVR ATmega32U4 16MHz, Flash: 1MB, RAM: 2.5KB. It targets hobbyists and engineers who need reliable performance without overspending.
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.
The New Teensy 2.0 USB AVR Development Board ISP UDisk Keyboard Mouse Experimental Board AT90USB1286 Development and Testing earns its place in the parts bin. Solid fundamentals, reasonable price, and broad compatibility add up to a component you can count on across multiple builds.
What We Like
- Multiple I/O options: I2C, SPI, UART, ADC, PWM
- Hardware watchdog timer prevents firmware lockups
- Extensive community support and online tutorials
- Flash storage sufficient for complex applications
Watch Out For
- USB-to-serial chip may require driver installation on some OS versions
- Pin labels on the board are tiny and hard to read
- 3.3V logic only — needs level shifting for 5V peripherals
