Teensy 3.5 Breakout Board

My name is Luke Wormald and I am an undergraduate at the University of Kentucky studying electrical and computer engineering. I am the electrical team lead for the university Solar Car Team and a member of the IEEE student hardware competition team which annually competes at IEEE SouteastCon.

This year the IEEE hardware team is planning to move away from the Arduino Mega to a more powerful platform. The Teensy 3.5 was selected due to its expansive I/O, processing power, and its ability to be programmed in the Arduino IDE, making it accessible to everyone regardless of their knowledge level. This hardware competition requires a small robot to accomplish a variety of tasks autonomously in a short period of time and changes year to year. This board was designed to accommodate that with all I/O broken out to 3 pin headers, which can be switched between 3.3V and 5V. It has an onboard 5V switching regulator and two battery inputs, allowing for a separate battery to power the motors than the one which powers the Teensy and sensors. There is also room for a daughterboard expansion via header which receives 5 PWM pins, battery power, 5V, and 3.3V. The intent of this it to allow flexibility in selecting motors and motor controllers. The board design has already been completed along with component selection. The board is two layers and 4.50” x 2.85” in size with standard thickness copper.

The sponsorship of this PCB would be greatly appreciated as we are not a particularly well-funded team. This board was design with the intent to last us multiple years of competitions, so any contribution would be put to good use.
