Neat package! What is that CAN BUS Transceiver board you used?

Welcome to MVS.

Are you going to contribute a Gerber file to the project?

What chips did you use?

Looks like you are drawing power from Vusb. In the current schematic that is listed as an unknown. Can you confirm Vusb has significant power to run the assembly?

for CAN I use max3051 (3.3V), powered direct from teensy (max 250mA), https://www.pjrc.com/teensy/card10a_rev2_web.pdf
max3051 maximum current 70mA x 2 = 140mA (https://datasheets.maximintegrated.com/ ... AX3051.pdf)

gerber and box for 3D attached

USB 5V 500ma is standard.
Teensy 4.0 current is ~100ma.
~100ma + 140MA = ~250ma.
~ 50% of the minimum standard.
No risk of overloading the USB port or coming up short on power.

Is this intended for swapping CEM modules with used ones without dealer involvement?

A part of that, yes. We miss acloning software that pulls the flash and EEPROM from damaged CEM over CAN and writes it to the donor CEM.

Would you like to make some functional copies and sell them to a neighbor country prie Mažeikių?
