Ooh - good point. Might just have a go without running a power supply first then!

Okay. I think I will still give the Teensy an auxiliary 5v power just to make sure it's sufficiently powered up though. Yeah the schematic says to connect one of the CAN boards to CAN HS+ and HS- and the other to LS+ and LS-, OBD Pins 6,14,3, and 11 respectively. Plus the CAN Gnd on Pin 5 to the Tee...

no there is no need to draw from the OBD port as the CAN transducers are powered on the teensy & also powered on the host. . it is worth noting that you should also earth the teensy to the earth on the OBD connector. i was informed to do so on here which i did do. But what are you powering the ...

Good info, thanks. As it happens I already was looking at just a bare connector so I'll just grab some ethernet cable for the rest! I take it you're drawing power from the OBD port too? I've got a few 5v UBECs kicking around from my remote control stuff so I reckon one of those with a nice fat capac...

Those CAN boards look identical to what I'm looking at, so I think we're golden. Basically what I'm planning to do as well!

By attaching a jumper between them? Seems counterintuitive in my head as surely that ensures the CAN H and CAN L would be directly connected?

I've got the software side of things looking good so I think I'll pull the trigger and start playing!

I mainly wanted to just use a Teensy as I want to make things as simple as possible on the programming side of things. I suck at programming so I'd prefer to just build the circuit, execute the code and get my PIN. So you reckon that the plan to use those boards is sound as long as I desolder the 12...

Hi all. New to this and I'm sure this is a pretty noob question to ask but I'm just wanting to make sure. I'm looking to crack the CEM pin for the two Volvos I have - A T5 C30 and D5 V50. I know Modunlock do a complete off the shelf solution using custom PCB crackers but on their website they also m...
