HR Circuits

EVDrive: a ready-made circuit board for your science competition electrical car.

EVDrive is a PCB laid out and labeled for your microcontroller, stepper drivers, motors, encoders, and gyro sensor. Skip the custom circuit design and wire in the parts you already trust.

Why teams switch to HR Circuits

Most kits hand you loose parts and a stack of files. Ours hands you a finished board.

No need to design

Every header is labeled and laid out. Drop in your microcontroller, drivers, motors, and sensor, then mount it to your chassis.

Built for feedback

Layout supports encoders on both stepper motors and a gyro sensor, so your heading and speed stay under control.

One low price

$20 for the EVDrive board. $145 MAX for the whole kit.

Built by a team, not a factory

EVDrive came out of building electrical cars for a science competition team. Loose wires and late-night soldering before meets got old, so a better board got built.
