Description
Volvo CEM Pin Decoder
This PCB allows the use of a Teensy 4.0 and a pair of Bosch CF160 transceivers to run the wonderful software found at https://github.com/vtl/volvo-cem-cracker. This will allow you to "crack" the CEM pin, allowing you to reconfigure the vehicle. I have confirmed that this works on my P2 V70 R (MY 2007).

Check eBay, that's where I got mine. https://www.ebay.com/itm/192811194444
Can i buy two SN65HVD230 CAN Boards and remove their chips to put in this circuit
Also, where are the resistors r3 and r4 meant to be placed on the circuit
?
wondering this as well
I found the answer elsewhere: the resistors aren't needed when connecting via OBDII (only if you plan to connect directly to the CEM on the bench). Now I don't know how to run the code and do the actual cracking...
