Description

Hardware - CAN enabled small input / output expansion board. Switch panels, steering wheel buttons/knobs, etc.

README

CANBoard

CANBoard is a simple CAN enabled IO board, specifically designed to be used in devices like steering wheels/button boxes/panels/etc.

• 8 digital inputs
  • Ground switching
• 5 analog inputs
  • 5V max
• 4 digital outputs
  • Low side switch (open collector)
  • 0.5A max each
• STM32F303K8
• KiCad 7.0.0

Goals

• Create a low cost device that my friends and I can use in our project cars
• Use components that are easily soldered by hand (hence 0805) and are preferably from my stock of frequently used parts (ex: LD1117S33CTR)
• Share my work with others for reference, inspiration or collaboration.

If this project does help you in any way, I'd appreciate a message!
