RH Circuits
Circuits built for the track, not the bench.
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 RH 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.
Reliable by design
Onboard fuse and reverse-polarity protection, modular sockets, and a hardware network switch keep it pit-ready.
How EVDrive compares
Most kits on the market give you raw parts and a set of files. You design the circuit, print the frame, and wire everything by hand before you can even test your car. That takes time, and one bad connection can cost your team a run.
| Feature | EVDrive | Build-it-yourself kits |
|---|---|---|
| Circuit design | Board layout done for you, labeled and ready | Design and wire your own circuit from scratch |
| Wiring | Labeled headers for your MCU, drivers, motors, and sensor | Loose wires and breadboards |
| Motor feedback | Layout supports encoders on both stepper motors | Rare in DIY builds, needs custom wiring |
| Soldering | Mostly plug-in headers, minimal soldering | Extensive, and mistakes are easy to make |
| Setup time | Populate the board and wire it in the same day | Hours designing and wiring before your first test run |
Less time building, more time racing
EVDrive exists so teams can spend their season tuning strategy, not designing a circuit. You still source your own microcontroller, drivers, motors, and sensor, so your car keeps its own look and feel. The layout just works.
