Our Review
After integrating the Teensy 4.0 iMXRT1062 Microcontroller Development Board (Lockable Version) into several test builds, we found it to be a capable component for the price. Key specs include Processor: ARM Cortex-M7 600MHz, Flash: 1MB, 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.
The Teensy 4.0 iMXRT1062 Microcontroller Development Board (Lockable Version) 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
- Built-in USB for easy programming without external programmer
- OTA update capability for remote firmware deployment
- Low power sleep modes for battery-powered applications
- Multiple I/O options: I2C, SPI, UART, ADC, PWM
Watch Out For
- Limited SRAM constrains complex data structures
- ADC accuracy is limited without external reference or calibration
- No onboard battery charging circuit
