Our car uses CAN bus for device communication. APPS sends current pedal position over
the bus as well as diagnostic information regarding any errors that occurred during its
operation. 

APPS is a part of the front-box - a PCB stack that’s located at the front of the car which we
already covered in this article - thus it has to follow a certain pinout that allows for easy
debugging and connection with other boards that’s space efficient and easy to disassemble.

Manufacturing

PCBs designed by our team are manufactured by JLCPCB- a hardware production
company that specializes in batch PCB production. You can create PCBs with up to six
layers, and order a batch size that fits your needs. Batch production is beneficial since
during PCB assembly, many things could go wrong and the board could get damaged, that’s
where excess copies come in handy. If unlike us you don’t enjoy assembling PCBs, JLCPCB
has got you covered as PCB assembly is also a part of their offer!

You will be forwarded to the order editor where you’ll find plenty of options to customize your
batch of PCB to fully meet your needs. Firstly you’ll need to upload your gerber files archived
into .zip or .rar format.
