Our Review
After integrating the 1SET 2.0 Teensy USB Development Board 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: 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.
For the price point, the 1SET 2.0 Teensy USB Development Board delivers what you need without unnecessary complexity. Recommended for hobbyists and engineers working on projects where microcontrollers & dev boards components are essential.
What We Like
- Built-in USB for easy programming without external programmer
- Extensive community support and online tutorials
- Multiple I/O options: I2C, SPI, UART, ADC, PWM
- Breadboard-friendly pin layout speeds up prototyping
Watch Out For
- 3.3V logic only — needs level shifting for 5V peripherals
- Limited SRAM constrains complex data structures
- WiFi and Bluetooth antenna is PCB trace only — limited range
