Isn’t it fun to take stuff apart and see how things are made ? Well Michael over at EDN likes to as well! He’s got one of those cheap-y eBay Bluetooth OBD-II adapters and while what’s inside isn’t much of a shocker, it’s still nice to look at how things are made.
Inside is a bunch of power regulation, a CAN bus transceiver, a Microchip PIC and a ready-made bluetooth module. Usually when you crack these cheap clones apart the soldering looks pretty shoddy, but this one looks pretty clean except for the Bluetooth module for some reason.
Check out the full teardown.
