- Can you test your board on its own without a whole system attached to it.
- Do you need any extra tools to test your board? (CANable, power supply, multimeter, dummy i2c device, etc….)
- Can you easily breakout your connectors testing or do you need test points?
- Do you have an easy way to debug communication lines if something goes wrong?
- Can you test your design without soldering on the expensive components first?
