Ollie is an isolated, multifunction interface module and USB-to-isolated-UARTx2/CAN/USB/RS485/RS232 converter. This versatile device combines our most commonly used interface modules into one safe, reliable, compact, and affordable package.
Need quick access to safe power? Ollie’s isolated power output requires you to set a voltage level before plugging in the host USB, which prevents accidental changes in voltage. All interfaces are ESD protected.
The main objective of this project is turning this mess of wires (left) into a neat and useful device (right)!
Ollie prioritizes safety through isolation, which will save your computer from damage if things go wrong when you’re interfacing with high voltage devices.
Ollie is the perfect tool for hackers and field engineers; a compact device to keep in your tool box whether you’re traveling, hacking your car, or just need quick access to power supply without worrying about damaging your laptop.
Ollie can be used with a configurable DB9 adapter which can be plugged in instead of the screw terminal. The function can be selected by moving all three DIP switches to the desired configuration. Also CAN OBD-II or CiA 303-1 function can be selected using the jumpers.
Ollie comes with a custom protective enclosure, so you can feel safe using it in any situation.
We designed Ollie as the perfect multi-tool for hackers and field engineers; to be a "Swiss Army knife" of interface modules. With that in mind, Ollie can be used in a wide range of situations, but here are some ideas of where we think it is useful.

"Ollie is not the first of it’s kind, there are several tools... which possesses similar features and are used for similar purposes... but all fall short in one way or the other when compared to Ollie."
