How to power Teensy 4.1?
USB
- Teensy is powered with a PC or USB hub trough a USB cable. The USB power is given at the VUSB pin, which is connected to VIN.
VIN Pin
- If not use USB power, 5V power can connected with a VIn pin. Since Vin and VUSB are connected and power is not given to Vin with the use of USB.
3.3V
- The Teensy 4.1 comes with a voltage regulator that decreases five volts VUSB / VIN to 3.3V for normal use with the main processor and other components. The 3.3 V pin can used to power more circuits. The highest recommended voltage of 3.3 volts is 250mA.
