Pins are not 5V tolerant. Best For Robotics, audio, data logging, Ethernet projects, controls, lighting, sensors, and high-speed embedded systems Power and Wiring Notes Teensy 4.1 uses 3.3V logic. Do not connect 5V signals directly to its pins. Using 5V signals may damage the board. The board can be powered through USB for basic testing. For external power, follow Teensy power guidelines carefully before connecting VIN and USB power. Important Notes This version includes pre-soldered male headers. Ethernet PHY is built in, but the Ethernet connector kit is sold separately. Use 3.3V-safe sensors and modules. Use a compatible USB cable for programming. Install Teensy support in Arduino IDE before uploading code.
