Kit Assembly
2.6 Crystals
The crystals are getting mounted in the same way how before the LEDs. Only that here
you don't have to look for the polarity.
The 20 Mhz- crystal depends to the CAN-Controller, to the microcontroller the crystal with
16 MHz. The round clock crystal is giving the time for the real time clock.
