Teensy with headers

Teensy on PCB

The Teensy board can be mounted either on headers (left) or directly on PCB (right). The first option is recommended as is allows easy replacement in case of damage.


Adjust potentiometer to be 330 Ω between the two illustrated pins or solder directly a 330 Ω resistor between those pins.
