As with the original version of Ollie, Ollie v2 is an isolated, multifunction interface module and USB-to-isolated-UARTx2/CAN/RS485/RS232 converter. This versatile device combines our most commonly used interface modules into one safe, reliable, compact, and affordable package.

Ollie v2 prioritizes safety through isolation, which will save your computer from damage if things go wrong when you’re interfacing with high voltage devices.

Ollie v2 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 a power supply without worrying about damaging your laptop.

The main objective of this project is turning this mess of wires (left) into a neat and useful device (right)!

What’s New in v2?

This latest version of Ollie comes with a host of improvements:

Features & Specifications:

Use Cases

We designed Ollie v2 as the perfect multi-tool for hackers and field engineers; to be a "Swiss Army knife" of interface modules. With that in mind, Ollie v2 can be used in a wide range of situations, but here are some ideas of where we think it will be useful.

Custom Enclosure

Ollie v2 comes with a plastic protective enclosure, so you can feel safe using it in any situation.

Custom DB9 Adapter

With the optional DB9 v2 adapter, Ollie v2 is easily attached directly to a DB9 cable. Note that the DB9 v2 adapter is not compatible with the original Ollie, nor is the original DB9 adapter compatible with Ollie v2.
