OSCAR is an open-source controller for animal research that enables flexible control of a variety of industry standard hardware with platform-independent software. OSCAR offers millisecond latency with a flexible array of inputs and outputs at a fraction of the cost of commercial options. These features position OSCAR as a valuable option for improving consistency of behavioral experiments across studies.

OSCAR: common questions

What microcontroller does the OSCAR use?

The OSCAR is built around the A000067, from the AVR/Arduino family.

How big is the OSCAR PCB?

The OSCAR measures 155.6 × 120 mm, has 4 copper layers and is 4.69 mm thick.

How many components are on the OSCAR?

139 components, from 15 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the OSCAR design files?

From the tne-lab/OSCAR repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the OSCAR design in my own project?

Yes, under the terms of its MIT license, which tne-lab chose for the repository.

Can I test firmware for the OSCAR without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
