ReGary: common questions

What microcontroller does the ReGary use?

The ReGary is built around the GW1N-UV1P5LQ100, from the FPGA family.

How big is the ReGary PCB?

The ReGary measures 38 × 38 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ReGary?

38 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the ReGary design files?

From the jbilander/ReGary repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the ReGary design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which jbilander chose for the repository.

Can I test firmware for the ReGary without the hardware?

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